Hello again everyone, I'm still going about emissive stuff
This time I am wondering if there is an issue with xpu when rendering vdb volumes (density)? I am importing a vdb density volume into Solaris and I'm giving it a volume shader where I pipe in the density into the emissive input of the volume shader. I am also multiplying this density with a constant value.
When I render this with Karma cpu I get an expected result, but when simply switching to xpu I get something completely different. It seems to just render out a big box of a volume. Please see the attached image.
Why is this happening? What can I do to get things to render correctly in xpu?
@brians : Thanks for your reply. Yes, I am using the kma_volume vop. I cannot post the entire scene, but I was able to reproduce the issue in the attached example file. I am using Houdini Indie 20.0.544, on Windows 10. Should I perhaps bug report this issue?
- The Mtlx_geomprop node is reading "density" field whereas the "volume_0" prim sampling field is "gas". - The geomprop node is strict typing. The "gas" field is of float type whereas the "mtlxgeompropvalue1" is configured for Vector3. This needs to be change to float type as well otherwise it returns the default value. - You would want to also assign a valid material for "volume_1"
