I seem to recall a fix but cant seem to remember or find it. When I open the 3ds Max Material Editor, the sample objects are very noisy/grainy as if they are only being rendered with very few iterations. in the "Advanced" section of the render dialog, the attribute for "Material preview quality" doesnt seem to have any impact.
Hi amdgaryd, should work... You may need to update thumbnails after adjustment (Reset Material Editor Slots in ME or Clear Preview Thumbnail Cache in SME).
The difference in quality is rather visible.
16 vs 32 vs 256.
