3dsmax scripts - progress capture

Renalicious · Jul 2009

Hey peeps,

I'm kind of new here so go easy on me

Over the past couple of months as I've been developing my portfolio, both art and code, I started playing around with max script to make some simple scripts and help take the monkey work out of Max. Basically make my way towards becoming more of a technical artist in the industry, rather than an artist with technical ability

Recently Adam (I'm sure you guys know him) gave me the idea of making a max script that will take a progress shot of your max scene with a simple press of a button. Good idea! So I took the idea and expanded it a bit more.

Capture tool script

Installation:

Open the rar file
Place the MCR file into "..\3dsmax2008\Scripts"
Run the macro script (Nothing will actually show up) MAXScript -> Run Script...
Assign the macro script as a button... Customize -> Customize User Interface... -> Group = Main UI, Category = Ren Tools
Click and drag "Ren's Progress Capture Tool" onto a toolbar
Click the new button to open up the floater window
Read usage below

Progress Capture:

The list box contains the names of all cameras in the scene, you can select the desired angle you want to capture. If there is nothing listed (IE, there are no cameras), the tool will use the perspective view.
You can create a new camera with the Create Camera button. If you have a camera selected, the selected camera will be reoriented to the current view.
Checking the Free Camera check box will make the camera a free camera instead of a targeted camera.
Capture on autosave will attempt to capture a progress shot based on the autosave timer. CAUTION: if your scene takes a LONG time to render, you may either want to turn this off, or lower the render settings.
Quiet, no virtual buffer will not display the rendered image in a window, but will still save it out.
Pressing the Capture Progress button will automatically render and save your scene based on your current render settings. The file will be saved to the same directory as the max file, and it will be incremented up to 100.

There isnt a lot of functionality that I will be adding to this tool as I would like to keep it simple. At most the listbox could auto update, or at least have a manual refresh, not just when a new camera is added.
Additionally a more robust file management system might be handy.
There may be unforeseen bugs left over, so I just let me know if you find any!

Fixed a bug caused by bad syntax. It should work without a problem now

some screenshot might be nice to get me more in the mood testing the script

You could also use the preview render to make snapshots of the view port as that might be more interesting to modeling people. A mix of zoom extends for auto camera on a selection of objects could be nice (like if one works on details in a model and only wants to capture that detail).

I see some nice potential for this script idea, keep it up

I like the idea of using a static camera, so you kinda get a time-lapse WIP video for free!

I definitely think that renderhj's suggestion of just grabbing the viewport is a good one, personally I don't want to wait for a render every time (especially if I have settings set up for high-quality light tracing etc.), usually a viewport screengrab will do the job for WIP and time-lapse purposes.

Maybe add an option to choose between render or screengrab? That'd be really cool.

Also, will you have to have the window open all the time in order for it to work? Or will it sit quietly in the background, writing out images without cluttering the interface? And why does it only increment to 100?

Ah, yes yes. This certainly should be a screenshot of your active viewport and not a render. Essentially doing what alt-prnt-scrn does with the additional functionality already in the script.

Renalicious · Jul 2009

Hmm, I'll look into grabbing the viewport, though it may end up being a Windows thing and outside of Max's capabilities.

But here is an image of the progress tool

Renalicious · Jul 2009

After a bit of digging there is definitely a roundabout way to capture the viewport

I'll release a new version of the tool once I have it coded in. Shouldn't be more than a new button and checkbox

LEViATHAN · Jul 2009

Looks coolies, always wanted this.

Thanks.

Hey R I don't know if this what you are looking into already, but animation>preview should give you exactly that : a viewport capture taken from within Max. Only thing is that you might want to force in 'shaded mode' to avoid taking wireframe shots now and then..,

Szark · Jul 2009

There's also 'Tools > Grab Viewport' for getting a still image. I'm not sure if you can access that with scripting or not, though.

renderhjs · Jul 2009

you can, there is something called

gw.getViewportDib()

that returns the current active viewport as bitmap object which you can dump on the hard driveas an image.

Ok I have the script basically where I want it, but I have to work on the timing a bit. Apparently viewports don't like to switch from one view to another instantly.

With that said, I think some people might be opposed to having controls cut and their viewport move around for a split second. Although it would take longer for more complex scenes.

So what I may do is just simplify the script so that it will only capture the current viewport as is... while the rendered capture will use selected cameras etc.

EDIT:
Ok, here is the new maxscript. I also changed the file numbering to include a timestamp instead of a number, it makes things faster as it doesn't have to go through and check for existing files, and it's not limited to some arbitrary limit either.

I should also point out that the way this scrpit captures the viewport (using "gw.getViewportDib()") is for max versions 2008 and newer! I'm not sure how it will react with older versions of max, and I don't have time to test it out at the moment.
