C4D / Open VDB Sample File?

Is there a sample file of OpenVDB fire in C4D? I've tried working through the tutorial page and the best I get is smoke, but no fire. I've tried the sample explosion file and fire file. I must be missing a step and a sample file would be useful to see how it's done correctly.

Thank you!

Hi
fire need at least 02 grids (density and temperature). Just copy the list from Available grids to Grids (density, temperature, heat, vel.x, vel.y, vel.z, or v ect..) put space between the grid(density temperature)
The volume_sample_float and volume_sample_rgb are just remapping nodes

Just tried that. I still must be missing a step as it's just smoke. Is there a sample C4D file anywhere that I can use as a reference?

by having just (density temperature) in the Grid without assigning Standard_Volume Shader you should get the explosion rendered (with fire)
as I told you volume_sample_float and volume_sample_rgb are just for remapping, you can skip them The tutorial you mentioned should be updated, because that was for the older version.

Thank you! I started from scratch and your advice worked! It also applied what you said to X-Particles OpenVDB and it worked. I just had to swap out "temperature" with "heat" in the "blackbody" channel. What I really like about this is the slider for the temperature which is really nice! Thank you again!!!
