I’m trying to do an animation of a planetary flyby. Got a beautiful map at 4096 x 2048, which I try to apply to a sphere mesh. The preview window comes up black, and renders that way too. Reducing the map image to 2048 X 1024 and reloading the image works OK, but is too low res when rendered (camera passes near the surface).
Is there a size limit for images used as textures? If so, what’s a good way around it? Thanks!
I managed to handle up to 8192x4096 planetary maps, it they are PNG, not if they are TARGA, probably some issues on max memory size of an image.

I just ran into this problem myself with a 5120x5120 targa file. A quick check of the code shows a hard limit on TGA/targa file size of 4095x4095. (Yes, 4095x4095 as the test is >= 4096 for x and y size and the load fails.)
I looked briefly at jpeg and png code and didn’t notice this size check at all, so I’m assuming this is a left over limit from probably quite awhile ago.
I’ll file a bug report on it so its not lost. At bare minimum, the test should be changed to > 4096, but could either be removed completely or increased for today’s larger memory and more powerful computers.
