V-Ray Fur on Imported Geometry

[Claudio Branch]

I use alot of imported terrain geometry in my scenes. But when I assign V-Ray Fur to one of these objects, it doesn't behave properly. I have included an image to showcase this odd behaviour.

 

The foreground shows imported geometry and the background shows a typical plane with a noise modifer. Both objects have V-Ray Fur assigned to them with identical parameters.

 

The fur on the imported geometry wants to "grow" down and completely straight. Flipping the normals will reverse this, but it's still no good to me...

Your normals are flipped on the imported geometry, your fur would follow the direction of the normals. Try applying a normals modifier and seeing what happens, you can also flip the normals in the meshes sub-object.

The normals are not flipped. This piece of geometry renders out just fine with it's mapped textures. The V-Ray Fur modifier is not accurately interpreting the orientation of the normals.

reverse the gravity on the fur then...

Even if it's rendering fine it might still be a normals issue,

you can also try attaching it to a box (Attach from the box...)

might be a scale issue as well...

I found an easy solution...

 

I converted the geometry to a proxy and reapplied the Fur modifier.

 

All is .

Cool tip,

Thank!
