I am trying to render a bump map with 3 delight. I am using RMan Bumpy.

In my Geometry Object - > Render - > Displace Bound = 1; Geometry as subdivision surfaces. But it doesn't work.

You should use 3Delight shader instead of one that comes with Houdini. It is PRMan shader ready to compile & execute with PRMan. They are not compatible with 3Delight as I suppose…

I have tried an other shader that works with 3delight and maya. Perhaps I don't write correctly the parameter in the generic displace->Renderman. I write this: “displace” “BumpStrength” 25.00 “BumpValueMap” “Cmap.tdl”.

I've got to render a displacement/bumpmap shader. But I have problems to set the displace bound. I turn on the displace bound in the tap “render” of the geometry of objects. But the displace bound seems that doesn't work. In the render the model is broken (holes). When I render to a disk file and I read it I can't find the displace bound attributes.
