For the most part my upgrading to the new texture tools exporter works. However I seem to run into issues when packing textures with an alpha channel. I’m not sure if its some sort of user error or display bug but every time I attempt to export a dds file using the new exporter. its discarding the pixels from my other channels where the Alpha is 0 (or at least photoshop, visual studio, and my game engine is reading as such).
As opposed to the legacy nvcompress the other channel information persists just fine. the channels of my parallax composite texture outside of the alpha remain. (would post more pictures but i only get one)
now with the alpha turned off after using Nvtt_Export in my batch script instead.
all information outside of the alpha is black
any ideas anyone has as to why this is happening would be greatly appreciated because i would love to upgrade to the new NVTT to be ready for more modern texture formats when needed.
p.s. apparently CUDA is turned off for BC3 compression? i dont remember the legacy tools being like this… can anyone confirm?
