I'm putting together a prototype and have been trying to find various outdoor scene cubemaps to render with different levels of a casual game. I'm looking for eihter terrain style, space, alien terrain, alien space, etc... if anyone knows a good site please let me know. Thanks

You actually call these skyboxes normally. Maybe this will help:

Skyboxes 1
Skyboxes 2
Skyboxes 3
Skyboxes 4

Terragen can make your cubemap images, tutorials are on their site.

thanks, these look promissing.

Also, can anyone tell me where to find directions on the Nvidia script plugin for photoshop called: nvidia_cubemapshuffler? I've found reference to it as part of the dds tools, but nothing that explains how to use it. I have various images I want to convert to the right dds cubemap format but I'm not sure how to assemble them. I found a good paysite to buy the images: skymatter.thegamecreators.com

Thanks

Use ATI's cubemapgen
