Hi J-S ;
First of all thanks to answer. It's so useful to me. I look at the
http://www.debevec.org/Probes/ which is so good project about skybox.
When I look your Skybox.cpp source code I couln't see
loadVerticalCrossCubeMap(cubemap); function. Is it only read the the textures
and sending a node. Or Is there any specific process in it?
Thanks so much..!
