Logos and everything load, but the background wallpaper stays white for systems 14-23 almost like it isn't releasing the textures so it can reload on the other systems. It won't create a new texture, but will change an existing one instead.If you can get away with some loss in quality, try compressing your bitmap in a format that your card can support(DXT for example).ДЄt about the 13th system the wallpapers are just white. Is loading a texture (a call to glTexImage2D) too expensive to perform for each frame in an animation? I think this method could give me the flexiblity I need, though it may be a bit of a memory hog.Thanks! I wouldn't recommand doing a call to glTexImage2D every time, If you can't load everything in memory, then you should look at glTexSubImage2D. This would mean that whenever a specific frame is requested, the appropriate OpenGL texture is loaded into video memory on the fly.My question is, is this a sensible design? I'm not sure this is very effecient. Since I'm using DevIL to load images, it seems like it would be much easier to load an entire image into system memory (including frames of a GIF and MNG file!) and then load only the necessary part of that image in system memory into video memory when it's needed.

(2) It's hard to support long animations with relatively high resolution frames because the textures become very large (2048x2048 pixels, for example).I've tried to add animation by altering one of three things: the actual texture in use, texture coordinates, and the 'slice' (3D texture r cooordinate).I just recently had a thought though. I've tried using 3D textures to get around this problem, but it hasn't been working well.

(1) I'm finding it hard to add support for animated GIFs and MNGs. Both involve loading a texture into video memory (after resizing it to be a power of 2) and specifying the proper texture coordinates for each frame of the animation.This works, but there are a few problems. I'm trying to do 2D graphics with OpenGL and supporting animation has been a bit difficult.Currently, two forms of animation are supported: Strips and Maps.

I've been running into some trouble with my little game engine lately.
