WARNING | attempting to get varying parameter 'Cd1' failed! out-of-range error

[Ilarin75]

Hello, I start a render and get this error on Houdini
The render starts and about 0.3% is done and it stops.
I use CPU only (no solaris) Houdini 18.5 py3

I use about 16 "geo" nodes to render the object. with 20 material nodes overall

if I just override the shaders to lambert, it works.
I can't spot any problem in any particular shader or geometry
it looks like if I just add more than X shaders it brakes
I can't see the pattern really
I had a situation when I just removed one detail attribute and it started to work, 0 logic in it really.
But I need that attribute to work.

I wrote to support about that and after like 4 replies they stopped replying to me. The issue is still there. I sent them the file and the scene with the error...

I had a similar issue in 3ds Max. The problem was one of the materials that had a node that wasn't supported. I would send them again an email asking for an update.

Oh right, under the subject "Houdini PDG Error"

I didn't expect a new support case in that old thread.
