I wish to display videos on planes, sides of cube, etc. similar to a computer monitor or projected image. In blender this is a material / texture type. I can't seem to find it in GG and google has not assisted me. Please point me at it, or suggest another product that may assist (appgamekit?). Thank you!

This cannot be done in Game Guru like it could in FPSC. In FPSC, you could simply select an AVI file to be a texture. The method Bored of the Rings is referring to is a workaround that involves making an atlas texture where you basically lay out every frame of your video on a huge texture and the shader just displays each frame one after another. It's totally impractical for anything longer than a few seconds though. Let's say your video is 25 seconds long; that's 625 frames at PAL 25 fps. Even if each frame is only 256 x 256, which is really low resolution but might work for a screen or something, your atlas texture would need to be 6,400 pixels wide and 6,400 tall. That's a huge memory overhead for something that's effective a background prop.

It's sad TGC never carried over this functionality from FPSC, I miss it dearly.

Great to see this was looked at in the past, nice links for those diving in.

Here's a random video, had to do a new shader for this one. Biotech 100% real

Thank you very greatly indeed Bored of the Rings, Avenging Eagle. Great info. My use case is much longer video, 4 streams, 30 minutes each in my test case. I feel a different tool set might be needed for my solution.

Video textures working in a forked/modified version of (old) GG Classic, it would be great to have something similar in Max at some point in the future:



Cheers.
