079c7f918cShort description of error
Volumetric emission no longer works if density of the reflective volume is set to zero, but it works if density is greater than zero.
Exact steps for others to reproduce the error
Add a cube.
Add a shader Principled Volume and link into the Volume of the Output node
Set Density to zero in the Principled Volume
Increase Emission Strength in Principled Volume
Nothing will show.
Now increase Density to 0.1 and emission will start to shine!
But the reflective volume material will also show in this case, which is a problem if one wants to apply a texture pattern to the emission volume, e.g make a glowing sphere with a gradient node or patterns with holes etc.
