I have tried to examine DDS files that contain half float cubemaps with PVRTexTool. It appears that half float DDS cubemaps are not supported correctly. Can you comment on this?May 20, 2016 at 4:56 pm #53764
Skimming through the code, it’s tricky to tell if this configuration is supported. Can you share a file with us to reproduce the issue?May 23, 2016 at 9:33 am #53765May 23, 2016 at 9:53 am #53768
Thanks Timo. I’ve reproduced (what I suspect are) artefacts in the surface render. For reference, can you also share a version of this image that renders correctly in PVRTexToolGUI?May 23, 2016 at 10:55 am #53769
No, it seems that 32bit float version of the image also is not shown correctly in PVRTexToolGUI. It seems that HDR images color values are somehow wrapped around.
I have also noticed that PVRTexToolGUI shows top and bottom cubemap faces unexpectedly swapped even in LDR cubemaps (at least when they are loaded from DDS). Either that, OR sides are rendered or uploaded to GL in wrong way up.
