Multiple UVs, tileable maps, and viewports, OH MY!

Cthogua · Oct 2006

I am trying to set up a faked ambient occlusion over a tiled map that will display in Max 8's viewport, and was wondering if anyone could offer some help. I have a tiled map on one UV set set to map channel 1, and a "light map" on a second, specific UV set set to map channel 2. I plopped both of these maps into an RGB Multiply and hoped the DX Display of Standard Material would chug through it...and it did, but it seems to only display both maps according to one or the other UV sets but not both at the same time. Is there a way to do that? Perhaps jsut some setting to enable? or is it a "Sorry, viewport doesn't do that

" issue?

Max won't display 2 UV channel's at the same time like that

Rather stupid if you ask me, since it's the #1 app for game content creation. You figure they'd be a little more game-specific by now.

PITA. One way around it is to set both bitmaps to use the same UV, and just alter the tiling in the material-level Bitmap Params. Assuming both use the same dimensions, just tiled and not-tiled.

Ben Cloward posted a new custom shader for 3dsmax that Ryno requested, which I believe displays a lightmap on a different UV channel on top of a main texture. His post is at the bottom of that page. Might be what you're looking for?

yeah, we had the same problem recently but we just moved over our ingame-shaders to 3dsmax and ran them as dx9 shaders, and that works great ^_^

yup, thats exactly what I was looking for, thanks! Now for the follow up question, is that custom shader stored with the .max file or will in need to be loaded by the person viewing?

MoP · Oct 2006

The person viewing will have to have the .fx shader downloaded and installed in the same location as the person who originally saved the file, I think.

Cthogua · Oct 2006

hmmm...Do you think for an art test it would be too much to ask, if the .fx file was sent with the max file and textures (obviously with a mention that Ben Cloward made the DX9 shader enabling me to overlay the light map), for them to drop the little .fx file in their maps/fx dir??

Couldn't you just put the fx in the same folder as the max file and load it from there?

That way they don't have to place the file.

MoP · Oct 2006

that might work, yes
screenshots of it should be fine though surely?

sinistergfx · Oct 2006

Aye, I would find it odd if source files were required for an art test.

Cthogua · Oct 2006

Sinister: I'll give that a whirl, I suppose it doesn't HAVE to be in the max dir

You know that's funny...I had just assumed the art test submissions would require the source files...but they never specifically mentioned that. I'll shoot them an email later today asking for some clarification.

Cthogua · Oct 2006

Yup, turns out they want the source files after all. I'll have to give Sinister's idea a spin
