Volume rendering workflow houdini to clarisse.

Unread postby atezel » Mon Jun 01, 2020 11:58 pm

Hi guys,

I have started dabbling with the PLE and so far clarisse is a joy to use, really looking forward to diving into it more.

I have been having trouble figuring out the volume workflow though. The online docs are really brief and don't explain much. I have exported a vdb sequence from houdini which has the usual density, temp, vel fields and I can't figure out a way to read in fields for the emission attribute in the clarisse vol shader. What is the recommended workflow for volume rendering in clarisse with vdb's?

Thank you for any help!

Hi,

Import your vdb in Clarisse. Then in the attributes click on detect sequence to make the sequence readable. After that, you have to use the extract property texture node in order to read the exported properties like temp, fuel etc ... For an explosion emission, you will extract the temp and use this property to drive the temperature scale of a black body and then plug the black body in the emission slot of the volume shader.

Here is a video showing that https://youtu.be/YEiF_tuZYsg?t=280

You can watch both parts of the video to have a good insight of bringing vdb from houdini?.
