maxscript that exports UV as selection into photoshop

dejawolf · Mar 2009

hi All, been working all day on this thing. its a script that exports an objects UVWs from 3ds max into photoshop as a selection. its currently very rough, mostly because i'm not a coder,
and because i started messing with javascript 2 days ago :P

its mostly for practice and proof of concept.

if selection.count > 0 then

(
output_file = createfile "C:UVWscript.js"
docusize = 1024
format "var docSize = %;n" docusize    to:output_file--write to file

for i = 1 to NMV = polyOp.getNumMapVerts $ 1 do
--start of map vertex array. this goes into the V = Array(x,x,x) part.
   (
      format "var V% = Array(" i  to:output_file--write to file
    mapvert = polyOp.getmapvert $ 1 i

     --write the first map vertex
     arrayvert = mapvert[1]*docusize
     intarray = arrayvert as integer
     format "%," intarray  to:output_file--write to file
	 --write the second map vertex. this one is inverted, because of 3ds max's non-conformity!!
	 arrayvert = (1-mapvert[2])*docusize--the mapvert is a value from 0 to 1
     intarray = arrayvert as integer
     format "%" intarray  to:output_file--write to file
	 format ");n"  to:output_file--write to file
)--end for i

 for i = 1 to NMF = polyOp.getNumMapfaces $ 1 do
--start of map face array. this is the 
   (
   	 format "selRegion = Array("    to:output_file--write to file
     mapface = polyOp.getmapface $ 1 i
      for E = 1 to 4 do
 	 (
	 	 arrayfacevert = mapface[E]
		 format "V%"arrayfacevert  to:output_file--write to file
         if E < 4 then ( format ","arrayfacevert  to:output_file)
      )--end for E
 	  format ");n activeDocument.selection.select(selRegion, SelectionType.EXTEND);n"  to:output_file--write to file

)--end for i

close output_file
)--end if

its also got several limitations currently.

1: doesn't work on anything else but quads
2: doesn't work on mesh objects, or primitives, or anything else that isn't a poly object.
3: 3ds max exports it into a .js file. to open it in photoshop, you need to click file>scripts>browse
4:oh forgot, for some reason photoshop acts as if the file is open even though i told it to close the script in max.
so you need to create another script file, and copy-paste the output into that.
5: painfully slow

5: i don't know if it works with anything else but max 8, but i doubt it does.
6: same goes for photoshop. i was using photoshop CS1 for this one.
7: you have to manually set the document size of the photoshop file. docusize = 1024
for example tells it that the photoshop document is a 1024x1024 map.

then browse to C: \ and open the UVWscript.js file

todo:

1: make it work with other things than just quads.
2: port it to VB, once i'm done with the proofing, and make it so that

ah well, got lots to do, i'll be messing with this thing for the next few hours.
i don't think my brain has ever hurt this much before...

meshu = polyOp.getmapface $ 1 1
meshu[7]

currently looking at some way to increase meshu[X] until it returns undefined, and then
somehow break, and then save X into a variable.

Wouldn't using the build in Render UV's w/ just seam edges selected be easier? Of course you'd need to then use the magic want in photoshop, but selecting big chunks is super easy.

Cheers!

dejawolf · Mar 2009

ok got something:

while i < 10 do

(
i = i+1
print "lal"
if mapface == undefined then exit
)

short answer: no.
long answer: NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO.

edit: got it working with full polys now:

hahah. Point taken good sir!

edit: fixed the bug:

if selection.count > 0 then

close output_file

now for optimization.

oh, and here's a picture of the selection:

1280 polygons, took some time to autoselect in photoshop :P
but try and do THAT with the lasso tool in photoshop

Mark Dygert · Mar 2009

I'm not really sure I get the purpose of the script? Is it to transfer a selection from the UV editor to photoshop? If so, that's pretty handy nice work.

I've always used a photoshop action that looks for specific colors that I have set to be the default in the render UV dialog box. I render a template, open it in photoshop, hit F12 and it puts the solid pieces on one layer, and the wires on another. It also sets up some folders and layers with names. I agree it can be a bit tedious to wand select all the shapes... so hopefully your script does what I think it does ha!

/crosses fingers.

pretty much, yeah, but i still need to simplify the operations.
currently its probably as slow as rendering out a template of an object, and loading it into photoshop.
ideally its going to be a single-click, and the UV selection is instantly in photoshop,
but i think i might have hit the limit of what i can do with javascripting photoshop.

glib · Mar 2009

Psst, renderhjs already has a button that does this in his script (which also has a thread in this forum). Nice work though

.

[edit] I'm an idiot, I should have tried it first. renderhjs's just copies it to the clipboard, not any photoshop-side stuff. Ignore me!

dejawolf · Mar 2009

so far, i've failed to find a way to improve the speed of the JS,
but i added an "expand" function to it now, so that the borders are increased by 2 pixels:

if selection.count > 0 then

(
output_file = createfile "C:Program Files (x86)AdobePhotoshop CSUVWscript.js"
docusize = 1024
format "var docSize = %;n" docusize    to:output_file--write to file

for i = 1 to NMV = polyOp.getNumMapVerts $ 1 do
--start of map vertex array. this goes into the V = Array(x,x,x) part.
   (
      format "var V% = Array(" i  to:output_file--write to file
    mapvert = polyOp.getmapvert $ 1 i

     --write the first map vertex
     arrayvert = mapvert[1]*docusize
     intarray = arrayvert as integer
     format "%," intarray  to:output_file--write to file
	 --write the second map vertex. this one is inverted, because of 3ds max's non-conformity!!
	 arrayvert = (1-mapvert[2])*docusize--the mapvert is a value from 0 to 1
     intarray = arrayvert as integer
     format "%" intarray  to:output_file--write to file
	 format ");n"  to:output_file--write to file
)--end for i

 for i = 1 to NMF = polyOp.getNumMapfaces $ 1 do
--start of map face array. this is the 
   (
   	 format "selRegion = Array("    to:output_file--write to file
     mapface = polyOp.getmapface $ 1 i
	 NumFaceCons = 0	 
	 F = 1
	 while F < 50 do
	 (
	 	F = F+1
	 	if mapface[F] == undefined then (NumFaceCons = F-1 exit)
	 )
      for E = 1 to NumFaceCons do
 	 (
	 	 arrayfacevert = mapface[E]
		 format "V%"arrayfacevert  to:output_file--write to file
         if E < NumFaceCons then ( format ","arrayfacevert  to:output_file)
      )--end for E
	  NumFaceCons = 0
 	  format ");n activeDocument.selection.select(selRegion, SelectionType.EXTEND);n"  to:output_file--write to file

)--end for i
format "activeDocument.selection.expand(2);n"  to:output_file--write to file
close output_file
)--end if

i need some way to disable redraw in photoshop...

Tumerboy · Mar 2009

don't worry glib, that's why my first post in this thread is blank :P

Nice work Deja. Could definitely be useful for making good layer masks.

renderhjs · Mar 2009

if I understand it correctly the main flaw in adobes JS workflow is that you NEED to click each time the file > scripts > ... thingy?
isn`t there a way by passing through some parameters to photoshop?

e.g here is a maxscript that opens the current texture in photoshop using parameters that are passed through to photoshop
http://www.scriptspot.com/3ds-max/photoshopselectedmaterial

now if one could do the same with the scripts to be executed (e.g path to temporary script file) that would be nice. I was already searching but did not found anything yet.

Ryno · Mar 2009

I'm not sure I'm following exactly what you are trying to do here. (Using Max 2009)

In Unwrap UVW, you can do Tools > Render UVW Template > Mode (choose solid) > Render UV Template.

This will export an image with solid blocks for the UV elements, and it also includes Alpha. This alpha can be loaded as a selection in Photoshop.

renderhjs · Mar 2009

@Ryno: a few cons:
- not dynamic in size so you would have to define each time what resolution to use for the photoshop texture.
- requires to select the UV template so that there is a selection
- manually delete the layer afterwards after the selection

in a ideal way you would have:
- 3dsmax and photoshop running
then you select the faces in the UV editor - run the script and you would get instantly the selection of that in photohop in the same texture document that matches the objects texture from 3dsmax.

MoP · Mar 2009

http://www.zortech.de/uv2psScript.xhtml

I remember someone posted this a while back. It seems to do exactly what you are doing. Not sure how fast it is, didn't try it yet - but from the video it seems to be very quick. Maybe you can take a look at it?

renderhjs · Mar 2009

In photoshop, run the script by choosing File - Scripts - Browse... Select the script file from your <3dsmax root>scripts directory. Make sure the photoshop document you wish to use is open AND the active document. Alternatively, you can drag and drop the script file into Photoshop

- I wish at least that could be avoided out of the box - without assigning shortcuts ect.

MoP · Mar 2009

I think there must be a way, but I am pretty new to Photoshop scripting so I haven't found out yet.

renderhjs · Mar 2009

well like I mentioned before the script
http://www.scriptspot.com/3ds-max/photoshopselectedmaterial
is particlary interesting as it passes additional parameters to photoshop

the snippet of the particular part I mean

for b in bitmapsToLoad do (
	pathsToExec += """ + b + "" "
)
--DOSCommand execMe
shellLaunch photoshopPath (""" + pathsToExec + """)

some info about the command 'shellLaunch'
http://www.cgarchitect.com/vb/4328-blow-up-net-render-2.html#post31906

e.g

shellLaunch "e:/t.avi" "/play /loop"

launches the the t.avi file and tells the media player that supports the parameters /play /loop to play and loop the animation.
So what I would like to know where to read up the parameters Photoshop supports. I am hoping that there might be one that supports to pass through a script to be executed which would solve the misery of the runScript thing in photoshop.

MoP · Mar 2009

Ah! Droplets might help...?
http://www.photoshoplab.com/droplets-for-the-lazy.html

Also it's worth noting that if you save as a .jsx file and have #target photoshop in the script, it'll launch the app if it's not running. Might be possible to pass parameters to a script too?
This is VBS example but may work for Javascript too...

dejawolf · Mar 2009

sorry for the wait, i finally managed to get empire total war working :P
anyways i'm back, and i figured some way to launch the script from 3ds max.

here's the modified maxscript first:

macroScript saveUVstophotoshop category:"Dejascripts" tooltip:"unwrap UVWs into photoshop selection" Icon:#("GameTools",2)
(

if selection.count > 0 then
(
output_file = createfile "C:UVWscript.js"
docusize = 1024
format "var docSize = %;n" docusize    to:output_file--write to file

for i = 1 to NMV = polyOp.getNumMapVerts $ 1 do
--start of map vertex array. this goes into the V = Array(x,x,x) part.
   (
      format "var V% = Array(" i  to:output_file--write to file
    mapvert = polyOp.getmapvert $ 1 i

     --write the first map vertex
     arrayvert = mapvert[1]*docusize
     intarray = arrayvert as integer
     format "%," intarray  to:output_file--write to file
	 --write the second map vertex. this one is inverted, because of 3ds max's non-conformity!!
	 arrayvert = (1-mapvert[2])*docusize--the mapvert is a value from 0 to 1
     intarray = arrayvert as integer
     format "%" intarray  to:output_file--write to file
	 format ");n"  to:output_file--write to file
)--end for i

 for i = 1 to NMF = polyOp.getNumMapfaces $ 1 do
--start of map face array. this is the portion that prints "selRegion = Array(VX,VX,VX.....);"
   (
   	 format "selRegion = Array("    to:output_file--write to file
     mapface = polyOp.getmapface $ 1 i
	 NumFaceCons = 0	 
	 F = 1
	 while F < 50 do
	 (
	 	F = F+1
	 	if mapface[F] == undefined then (NumFaceCons = F-1 exit)
	 )
      for E = 1 to NumFaceCons do
 	 (
	 	 arrayfacevert = mapface[E]
		 format "V%"arrayfacevert  to:output_file--write to file
         if E < NumFaceCons then ( format ","arrayfacevert  to:output_file)
      )--end for E
	  NumFaceCons = 0
 	  format ");n activeDocument.selection.select(selRegion, SelectionType.EXTEND);n"  to:output_file--write to file

)--end for i
format "activeDocument.selection.expand(2);n"  to:output_file--write to file
close output_file
)--end if

shellLaunch "C:openscriptinphotoshop.exe" ""
)

and here's a link to the visual basic application (might only work with photoshop CS1, or on my computer)
http://www.dejawolf.com/polycount/scripts/openscriptinphotoshop.rar

put that stuff in C: \

i found this in the photoshop CS scripting guide:

Dim appRef As Photoshop.Application
Set appRef = CreateObject("Photoshop.Application")
appRef.DoJavaScriptFile ("D: \\Scripts\\MosaicTiles.js")

just pasted that code into a visual basic console project, changed the name of the script and path, and added a reference for photoshop, and seems to run nicely.
i'm now going to tinker and see if i can somehow get more stuff done in VB, and see if its faster too.
oh btw, that console window will show up until the script is done "rendering" the UVs.
and also, remember to have a picture open in photoshop, or it won't work.
oh and don't forget to have an object selected in max too.
very very hacky :P

oh, and last, its now a macroscript, so you can run it from a button.
but if you want to test if it works on your computer first, just put -- in front of the line that says macroscript.... etc.

dejawolf · Mar 2009

i think i might have figured how to do selection with visual basic.
now i just need to work around these VB 2008 incompatibility issues.. hrm.
DAMN YOU MICROSOFT!

dejawolf · Mar 2009

ok, got selection working in VB

doesn't seem to be faster though.. hmm.
guess i need to work on my selection algorithm then.

dejawolf · Mar 2009

actually i think this whole scheme is faulty. i think i'll instead try and find out if i can paste
a black and white image of the UV template that max has rendered, and load that into the photoshop selection quickmask area or something.

renderhjs · Mar 2009

might be faster yes

and easier to code

Titus · Mar 2009

Aslo i render UVs into PNG with alpha channel and it looks in photoshop like separate layer, and you can also select only wire or solid elements

dejawolf · Mar 2009

made another script.
this one exports the UVs as vectors into photoshop.
it doesn't work on objects with more than 1000 polygons though, photoshop just throws an error.

oh, and here's a modified UV selection script that only exports the selected UVs in 3ds max into photoshop.
spent some hours banging my head into the wall trying to figure out how to make UVs render out into a render window. so far i can draw single pixels.

some more modifications to the script:

this time it will automatically figure out the size of your bitmap, based on the size of the diffuse texture applied to the selected object.

output_file = createfile "C:UVWscript.js"

format "activeDocument.selection.deselect();" docusize    to:output_file--write to file
format "var docSize = %;n" docusize    to:output_file--write to file

--get the vertex selection first into the array I, and loop through it.

thanks.
its not a big change, just changed docusize = 1024 to docusize = $.material.maps[2].bitmap.width

maxscript that exports UV as selection into photoshop
