Hello, We are making .TGA animated sprite files. 3DS exports a series of single, small frame bitmaps. (each one is say, 32x32). Each frame is its own bitmap file. We want all frames of the animation to be in one TGA file, aranged sequentially in a set of rows, and we are currently doing this by hand in Photoshop. Is there an easier way to get these frames into one bitmap file? Is there a plugin for 3Ds Max, or maybe a script or third party program?

You can custom write your own software if you're feeling up to it. It wouldn't be to difficult to load in an array of images and arrange them together automatically.

If each animation has a set number of frames, you can create a complicated Photoshop action to automate through series of images.

I like to use ImageMagick for this sort of operation usually.

ImageMagick works great, thank you :)
