Hello everyone,

I´m having trouble with surface diagnostic tools in rendred viewport- Emap and Zebra, they not working with basic materials. When the object has default material it works in rendered viewport, but when I assign any material to the object zebra and Emap not showing anymore. I tried to restore default rendered viewport but no luck…

I use RH7 release 7.38.24338.17001

RTX 2070 SUPER / driver - 560.94

tried emap on sphere with just red plastic material, also tried blend with object color…not showing anything

Zebra not showing too

In shaded viewport it works. In ghosted too, without materials it work even in rendered viewport, so it has to do something with the materials or rendered viewport ?

Thank You for help or idea what could be wrong

Tom

Hi Tom, It could be a limitation for V7. —Mark
