Ornatrix, Maya (2022.1), and Redshift Proxies

I am creating a small animal with longish fur. To cover the body in hair at the necessary density I need many, many individual strands. To render in Redshift I need to turn these strands into individual meshes. My viewport becomes very slow and render times are astronomical.

I am looking into using Redshift Proxies but don't konw how to begin. Could someone please give me either pointers to tutorials or documents that would help me get started or some advice.

If there is a preferred mechanism / workflow to do such an animal with Redshift other than proxies please let me know.

 

Thanks,

Hi Greg,

Why are you turning the strands into mesh? Redshift supports Ornatrix hair natively, there is no need to convert it to mesh. 

To improve viewport performance you can decrease the Viewport Count Fraction parameter in Hairs from Guides. This parameter determines the percentage of the total strand count that will be shown in the viewport.

Interesting. When I didn't convert to mesh I saw no hair in the render. I read in the docs here that to support 3d-party renders you needed to convert to mesh. I will try now again, maybe I missed something, and post here after I try.

Thanks,

No. No luck. I select the body mesh, add hair from the Ornatrix shelf, choose furball, make some length and width changes, increase the count, and render. I see the hair fine in the viewport but not in the render. Then I assign a RedshiftHair material to the Furball instead of the hairPhysicalShader that is initially instantiated and still no hair in the render. I try to experiment wiht some settings but nothing produced hair in the render.

I am sure I am missing something simple.

Please help.

Thanks,

Greg

I have read this https://ephere.com/plugins/autodesk/maya/ornatrix/docs/1/Rendering_with_Redshift.html of course. The textures and shaders are not automatically converted. I do not see redshift in the attribute editor for the FurBallShape. It's like Ornatrix does not know Redshift is the renderer.

Here is the scene file.

The process that you described should work. What exact version of Ornatrix, Redshift and Maya are you using? 

Also, the documentation that you are looking at is for ornatrix V1. You should be looking here.

Maya 2022.1, Redshift 3.0.50, and Ornatrix 3.2.5.28338

The newer documentation to which you referred me to isn't substantially different in the basic case. And, yes, from the tutorials I have watched and docs I have read this should just work.

Any ideas on what I should check?

BTW, I have the same problem with Yeti. Nothing appears in the render even though it should. So this is likely either my configuration or Redshift.
