SaveRenderMesh

[izze]

Good day.

I was wondering if anyone could help me with getting instanced geometry to output correctly using Andy Nicholas SaveRenderMesh addon? I am able to get it to work properly with the Strand Tree addon, but have failed at getting a simple pointcloud with instance shape to output. After tearing apart the Strand Tree compounds, I fail to see what might have added to allow the Strand Tree components to output with this method.

I am attaching a screen grab of my pointcloud setup. I have made it as basic as possible. If I remove Instance Shape node and use a standard point shape of sphere or box etc, the pointcloud will output geometry correctly with SaveRenderMesh. But with Instance Shape, I get nothing. Same with Set Instance Geo. Thanks!

Hi, if you are instancing, SaveRenderMesh must be a shader of the instanciated geometry...

I have the shader on the pointcloud. And it does export correctly if I set particle shape to the standard sphere, box, cone etc. But when using actual geometry and the Instance Shape node, It fails. Funny it works fine with Strand Tree but not with a very basic pointcloud setup.

It could be that Softimage utilizes the MR standins for ICE instance rendering, not generating geometry.

But that wouldn't explain why it works with StrandTree

Yeah, weird eh? I do not see anything in Strand Tree emit leaves compound that would be any different then the image shown above. I'm at a complete loss.

It looks like the material with the SaveRenderMesh is on the pointcloud - Which doesn't get called because there are no "actual" particles (only the Cone's material is called)

I started to create a new scene with the same setup for all to look at. And during the process everything worked! I swore yesterday when I put the SRM material on the instanced geometry (not the pointcloud) it would only save out the one object. NOT the instances. Then later that evening I tried the same setup at home and proved the same results. I guess I have to chalk it up to user error. Man I hate that. Just to be safe I am going to try this a few more times to see if I can break it again.
