i was wondering if someone has the same issue when transfering VrayScenes from 3dsmax to Houdini, or if at least if it is a known problem…
So when i export a VrayScene from 3dsmax, load it in Houdini and unpack it to polygons some primitives have either only a reference to the material node but not the Material or the entire shop_materialpath is missing.
To further clarifiy, there is nothing special about those objects nor their materials in 3dsmax. They are simple ungrouped, unlinked Editable Polys with basic VrayMaterials …
1. Why do you need to unpack?
2. I’ll need a scene to figure out exactly what’s happening (unsupported (yet) shader? unsupported (yet) material assignment?)
1. I want to unpack to have access to some topologies in the szene and it is easier to find and modifiy the matierials in Houdini that way.
2. I could pack the scene and send a Donwload link to your email, would that be ok?
I reduced the scene to one object that shows the problem in Houdini and attached it here. I hope this helps.
BTW, what i found out is that the root of the problem is in the geometry not the Material. If i attach it to a newly created Editable Poly and export it as VraySzene the material path shows up in Houdini. Houdini_ShopMaterialPath_Problem.zip (84.3 KB)
Well in one case for axample there were certain meshes i wanted to add houdini hair to and this doesn’t work with packed geometrie. There were certain other small thing i can not properly recall right now, but generally i had the need to edit certain parts of the scene im more detail.
And after all you added the option to unpack, i just wanted to help reporting an issue.
Thanks for the heads up! I’ve logged the request as HOU-3566.
The issue seems to be specifically with the V-Ray Object Properties assigned to the node - I’ll check with the developers to see what steps can be taken to resolve the problem.
