Hi all,
I'm new in Solaris, I am trying to integrate the USD pipeline with some photogrammetry assets.
I created my USD asset and its variants with component builderand loaded as a Reference in scene.
Everything went fine until rendering with KARMA.
I have great problem with alpha channel for my geometry ground after dressing with scattered moss.
I tried to figure out if the problem was in the opacity of the moss material or in geometry backface culling, but I realized that something changed with Treat Polygon as Subdivision Surfaces in the Component Builder. I hid mMoss instancer to do some test.
Without b]Treat Polygon as Subdivision Surfaces
(less dots, but always visible)
With b]Treat Polygon as Subdivision Surfaces
I don't really know how to fix it!
I tried move to Arnold which does not give this problem.
H 19.0.383
Thank you

If you are talking about the alpha that has holes in it, I made a post about it here:
https://www.sidefx.com/forum/topic/83456/ [www.sidefx.com]
SideFX acknowledged the bug and said they'd push out a fix in upcoming releases (might even be out already?).

Hi beatreichenbach,
any news about it? it seems nothing change in 19.0589
Houdini 19.0.590 Due to the new dicing behaviour that reduces gaps between diced grids, renders with subd or displacement may produce different looking results. Thu. April 14, 2022
Houdini 19.0.590 All but eliminated dicing gaps and cracks from displacement and subdivision. Dicing Flatness property is deprecated and hidden. Thu. April 14, 2022
