I consider PVRTexTool to be pretty much the best tool I tried so far in terms of KTX2 support. The only thing I find to be missing is support for BC6H, R8\_SRGB and R8G8\_SRGB. Especially BC6H is pretty popular for HDR content, so it would be great to have it supported. I also noticed a small mismatch in that exporting a BC1\_RGB\_UNORM\_BLOCK texture again will turn it into BC1\_RGBA. Since this is an extra nuance to Vulkan it would be nice if BC1\_RGB could be officially supported too for export. Thank you for the great tool! ---
