Hi TNT- Designer,
There is no option to bake anything volumetrically in Pyrocluster.
Do you use “Soft shadows” for your scene? If so, please have a look here:
I hope I have answered the problem, with these simulation of “shadowing”, in a sufficient way.
If you use a different shadow, you might share an example scene, perhaps there are some parameters that are too large to get the precision you need.
The only kind of shadow that can be baked is the Soft-shadow, but to be more precise, it stores only these points as discussed (see link) and from there you get something like an result.
You might check as well with the support, if there is any technique to get what you need.
All the best
