Using vellum.
When connecting a collision obj, and switch on the ground in vellum solver node,
The view seems normal.
When diving in the vellum solver,
The collision obj and the ground turn white, from wireframe to shaded,
I think that's "normal"??????
(still want to know, how to turn the collision and ground "back" to the SOP appearance ????)
but,but,but
When back to the SOP level again, from the solver's DOP.
The collision, the ground, will always show as shaded geometry.
No matter what I do, they will always be there.
this is never happens in old version of houdini.
The only thing now I can do is to close houdini, and open again.
It really kills me when working.
Thanks for your help.
