Problem with color of density with GI and physical render in Cinema 4d

Hi there. My Prolem: If I render a Sim with physical render and GI the smoke is always black. I can change the Color of the density but nothing changed. If i set the illuminatino to “none” then it works but i lose the selfshadowing of the smoke.

Can anybody help me?

Works fine for me with fire and without. Post your problematic scene file up to check

thanks. I checked it and i think the problem is the hdri sky… Any experience with it?

TFD does not receive GI or HDRI lighting on Advanced or Physical Render. You need Redshift or Arnold for that. It can only emit You need multi scattering on and / or lights to illuminate the density
