Hiya,

Is it possible to get shadows cast from an object onto a geometry light? I'm using H15.0.397, rendering with the PBR engine.

I have a reflective (chrome) sphere sat inside a box geometry light, and my geometry light is set to use a HDR (rat) of an environment to emit light using a simple material exporting the Ce variable.

I would expect there to be shadows cast onto the geometry light from the sphere, which would then be reflected into the sphere itself. However it looks like the sphere is just reflecting the environment with no shadowing whatsoever.

How could I add in this ability? Do I need to tweak the shader on the geometry light, the sphere, or is there another workflow I should look into?

Any help is greatly appreciated!

Cheers,

Daniel

Hiya,

I'd like to format the output of my HE Asset so that the resulting geometry is formatted into a transform hierarchy in Maya. Is this possible?

I'd like something along the lines of:

|—Main_Group
| |—-Group 1
| |—-Group2_1
| | |—-MESH1
| |—-Group2_2
| | |—-MESH2
| |—-Group2_3
| | |—-MESH3
| |
…

Ah I'm sorry, I forgot to mention that I'm converting the curve to a polygon before extruding it. When I do this, I still get the two edge curves output through HE in Maya, but they are not there in Houdini.

My Asset is this-

Inside a Geo Node:
Object Merge Input1 Curve
Convert (default settings)
Extrude (default settings, other than changing depthscale)
Null (OUT)

When I create a curve in Maya, load my HE Asset and plug in the curve i would expect to get just one poly mesh. However it seems to also output an extra group with the two edge curves in it as well.

If I then go to Debugging->View Assets In Houdini, navigate to my OUT null and middle-mouse on it, I can't see any signs of extra nurbs curves in the houdini session. So i guess I'm just trying to figure out why its outputting the extra curves when they aren't there in the houdini session.



Thanks for your suggestion though! As I have setup a work around which converts my poly lines back into nurbs curves, extrudes those, deletes the bezier lines and converts the nurbs surface to poly. A few more nodes, but it seems to work!

Cheers,

Daniel
