PVRTexTool incorrect etc1 cubemap generation



PVRTexTool 4.1.6 (SDK build 3.5@3523712)

PVRTexTool has an error in the cubemaps creation.
Left image - rgb cubemap reflection (glGenerateMipmap(GL_TEXTURE_CUBE_MAP);).
Right image - etc1 cubemap reflection with mipmaps generated by PVRTexTool
There are artifacts (thin lines).

Please fix.


Can you confirm that in your rendering code the wrap modes are set to GL_CLAMP_TO_EDGE?


Opps! Sorry!

GL_CLAMP_TO_EDGE fixes the problem!
