Exact steps for others to reproduce the error
Works in earlier versions of blender 2.8 Beta



Event Timeline

Brecht Van Lommel (brecht) triaged this task as Needs Information from User priority.

Works for me with Intel Iris 6100.

What does not working mean exactly? It shows no volumes at all? Is there an error message in the terminal? Can you check if it's still an issue in the very latest build?

Tried the latest build. Still nothing. When I connect the Noise Texture node to the ColorRamp node everything stops working and I get no volumes at all. When I disconnect them I get the basic volumes back. No errors in the terminal.

I'm also having this issue with Smoke and Volumetric. They show up faint, if at all, and if I add anything to them in the node editor they simply disappear all together. I know back around the end of 2018 a lot of other blender users on Mac's were having this issue and supposedly a build came out that had fixed it. But I'm using the official release and the issue is still there.

My Computer Detials:
2017 iMac Pro 64GB 2666 MHz DDR4
3 GHz Intel Xeon W
Graphics Card: Radeon Pro Vega 64 16 GB
OS:Mojave 10.14.5

After extensive research, I've found that this is an issue with MACs that no one has a fix to and Blender is not attempting to fix or pay attention to. So if you want to use volumetric in Blender use cycles only or dont buy a mac apparently.

I would like confirmation that blender does not intend to fix this from the update from Will Crespo. So blender only partly works with Mac?

I cannot reproduce it on OSX 10.12.6

this is how it looks:

Thats because you are not using a Mac with a Vega video card. Its been confirmed on another thread that its a Vega specific issue.
