Thanks for your amazing work on Blender !!!

Works for me on linux. So this might be a mac specific bug.

I can confirm this running Mojave on a 2012 Mac Pro, Intel CPU, Nvidia K5000 GPU. More Details

Console error output is:

GPUShader: linking error:
ERROR: Input of geometry shader 'var0g' not written by vertext shader

System Information
Operating system: OS X High Sierra 10.13.6 (17G65)

Blender Version
Version: 2.80 (2.80 2018-12-14, Blender Foundation)

When I try to mix a mask for two different materials it crashes.
Or it might been displayer as 'pink'.

Video and File is provided. Just plug the mask mix and crashes to reproduce it.

I seem to be experiencing a similar issue, except with smoke sim, and on Windows, as I reported in the thread T59838, here is a copy of that text:

I have experienced a similar issue. Using blender-2.80-1c7695b8483d-windows64, when I render smoke in Eevee I get nothing. When I render in Cycles I see the smoke, when I render in "Workbench" mode, I also see smoke. In the viewport I can see it all correctly.

Windows 10 Pro, Version 1803, OS build 17134.523
NVIDIA GeForce GTX 960
blender-2.80-1c7695b8483d-windows64

Similar issue on my Mac MacOS High Sierra 10.13.6 (17G5019), iMac (Retina 5K, 27-inch, 2017), Graphics card: Radeon Pro 580 8192 MB. I can see volumetrics with Eevee, but it vanishes when I add any kind of texture.

Same here on a Macbook Pro


When plugging in the texture in the volume density the render does not show up. My light energy is at 20.
I followed this tutorial https://www.youtube.com/watch?v=ptpGVGL-b2k&lc=z22oyj2z1uzbypul4acdp431301jg4qdxt40xesoljxw03c010c.1549797310156409

I don't know if this is helpful, but as I have a bootcamp partition, I'm able to verify that on the exact same hardware, using a texture to drive volumetric density in eevee causes the volume to disappear on macOS Mojave, but works as expected on windows 10.

I can confirm this issue too on OSX Sierra 10.12.6 The nodes frome example below render as a blank picture:

Okay, now volumetric aren't showing at all.

They work correctly here on macOS 10.14 with the latest build:

I'm using blender-2.80.0-git20190315.35b78d9807c4 (downloaded a little over an hour ago), I'm on a MacOS Mojave 10.14.3, iMac (Retina 5K, 27-inch, 2017), Graphics card: Radeon Pro 580 8192 MB. Hooking any volume scatter or absorption to the cube makes it vanish in eevee

@John Grigni (JohnGrigni) Can you look up the console for any shader compilation error? This fix/bug report was mainly for world volumetric material, not object's.

Ignore my post. It's working. I was a dummy and didn't click on Volumetrics in the settings.

Can confirm the fix as well, works like a charm now, thanks for fixing @Clément Foucault (fclem)!

I can confirm it is working now as expected. Thank you for the fix!

Can confirm for Mojave. Great! Thx a lot!

This seems to be an issue again with the latest build. Having to use an older build now. Also where did User Preferences go?

@Steve (Xraller) can you attach the output of launching blender with the --debug option?
