Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.

Render to texture problem (OpenGL ES)

Hi

I can't render to a texture larger than 256x256.
I would love to render to 512x512 as I wanna map it to the screen.

What could be the problem. Works in simulator but not on the device. I'm using OpenGL ES 1.1 on 3gs.
glGenTextures(1, &drawTexture);
glBindTexture(GL_TEXTURE_2D, drawTexture);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, kDrawTextureSize, kDrawTextureSize, 0, GL_RGBA, GL_UNSIGNED_BYTE, nil);

// create framebuffer
glGenFramebuffersOES(1, &textureFrameBuffer);
glBindFramebufferOES(GL_FRAMEBUFFER_OES, textureFrameBuffer);

// attach renderbuffer
glFramebufferTexture2DOES(GL_FRAMEBUFFER_OES, GL_COLOR_ATTACHMENT0_OES, GL_TEXTURE_2D, drawTexture, 0);
