I have imported an STL file from a CAD app. Well, you know how messy it is modelling wise.
However in my experience with other apps it is possible to get normal renders with these kind of objects.
In Houdini I can't get a good render. I tried the node facet, normal, etc, but could not fix the problem. I think the “Polydoctor” node could come in handy, however I didn't manage to use it properly. Any ideas about which options I should set?
What's strange is that some materials increase the problem. Check the attachment. With the material “piano lacquer” I have almost a normal result, but with the “titanium” material, all hell breaks loose.
Any suggestion would be appreciated. Thanks
