I've got a render taking forever at the Voxelization stage ("Start Voxelization").
There are SSS and displacement materials in there, and the polygon count is around 620 000...
Is this too high ?

Thanks !

afaik, no parameters do - scene complexity, # of instances...these are what determines it. If it's taking a long time, it may be due to the presence of intersecting instances, so you could try checking on that.

Check that you're not using adaptive in the displacement settings, or lower the precision setting and see. What are your displacement settings and texture size for the displacements?

Thanks guys.

After making a few tests, I think displacement is the cause.
Lowering the precision and unchecking "Adaptive" did the trick.

Would it be possible to make the render log a bit more specific about what is taking up computing time ?

Cheers,

It's actually before voxelization that the displacement calculations happen. And this process is not multi-threaded. You will notice that once it starts voxelization, the process becomes multi-threaded. It is a request I have put in a few times to make these displacement calcs use 100% of my cores instead of 12.5%... Hint hint HINT.
