Hi folks, I just grabbed 36004 maya 2018 , 27959 and the Dome texture still not visible in the viewport, it was working fine prior to xmas .
Sorry , just noticed this older post… Dome light visibility in viewport - Issues - Chaos Forum
There was an issue with 2018.2, so if you’re using that exact Maya version, you’ll need to update your build - we recently fixed this.
If it’s not 2018.2 that you’re using, then make sure you’re have “textured” view enabled for the viewport and you’re on one of the OpenGL Core profiles in Maya’s settings and preferences > Preferences > Display > Viewport 2.0 Rendering Engine.
I Yolov, so sorry I forgot to return to my post to mention the Dome is displaying fine now since last build.
Thanks a bunch.
Ah, good to know 
I knew the fix got into the stable branch just recently. With each new update for Maya more stuff breaks, especially in the viewport so we are trying our best to stay ahead of the curve
