Hi,

I am bringing in some CAT scan data (16bit) to render in Houdini.

I have already transfer the data to a volume BGEO

It is currently just a grey scale render.

I would like to add some material where I can map the scalar value to some ramp.

What nodes in the Material/VEX-Builder should I consider using to bring in the volumetric scalar data in the BGEO's volume primitive and would I need to use principled material for the color to appear in the Mantra render ?




Cheers
