Note: actually using 4.26 stable release (but not a choice in the dropdown).
I’ve made a simple cubemap and saved it as a .dds file using Nivida Texture Tools Exporter. It is a modest 30 MB and has been saved using 22.214.171.124 RGBA 32 bit unsigned. Total res is 6,000 x 1000. Have done this before without any issues, but this cube map keeps crashing UE4.
I did try some other formats BC7, BC6, etc but received the “failed to import” message which I expected as those formats are not supported.
Anybody got a suggestion?
