Texture compression is a great!
However, It doesn't work with the standard texture slot. Why is this an issue? The standard texture slot is the only one which displays correctly in the Max viewport. The Octane materials and maps still look to be capped at very low resolution, perhaps 512x512, in the viewport. This makes working difficult.
This is one aspect of the overall poor quality/compatibility of Octane materials and lights in the Max viewport.
Would it be possible to make compression compatible with the standard texture slot, or to fix the viewport display of Octane maps such as RGB Image?
