@Ascensi Time is of an essence in most production environments. And soft cloth physics is one of the most time consuming feature to deal with.
As you said not many people are willing to get under the hood for broken belt replacement. So I am sure you are going to sell lots of copies.

... As I dug deeper into this I found out that Iray does not really like displacement maps.
While iClone has no problem dealing with displacements, Iray would suffer greatly.
(Suppose there was a reason they put "Preview Tessellations and Displacements" check box there).
OK, so I went a little overboard with this. 80K tris for a foam plane and tiled displacement map for it.
The Iray initialization went from a few seconds to whooping 10 minutes... Wonder why??
Only after displacement map removal I got normal initialization and render times
I could probably draw the same with regular base color texture. But still wonder if it is NVIDIA, or iClone implementation deficiency.
UPDATE: The "Light hierarchy..." message gave me a clue... It is problem with lights.. not displacement. Or rather combination
I also have a Glow map for the foam plane. If I take glow map out and leave displacement in place I also get normal initialization times.
Glow map is considered a light source. And it looks like displacement map multiplies light sources for the mesh which otherwise should be just 1 (one).
And this is where 10 minutes delay is coming from. Definitely a bug and I would report it after more tests....
