Solaris Arnold Displacement

hello guys ! I am currently trying the usd pipeline and I have an issue with the displacement in solaris, in the pic below on the right you can see arnold performing on OBJ level whereas on the left it is inside Solaris, issue seems to comefrom displacement intensity/bounds and subdivisions.

does someone could tell me how to get it work ?


houdini 18.5.408

htoa 5.5.0.2

arnold 6.1.0.1


big thanks !

It looks like a scene scale issue. Is the USD reduced by .01?

I don't think it comes from here, I checked my unit length (m) in Houdini preference, it is set at 1m.

Also, I settled the config layers I have in my nodes tree at 1m (by default greyed out at 0.01).

Finally I tested the subdivision in Solaris vs regular, the parameter doesn't pass to the USD network, it just doesn't affect anything.

the render I posted above is from the same scene, same meshes. no transform were created in solaris node tree.
