OTOY Forums

Hello,
I'm trying to use Cinema 4D's Substance Shader with Octane 2020.1.5-R2.

The color pass seems to work okay in the Diffuse channel, but the Normal pass' thumbnail appears to have a different gamma than in the Substance Asset Manager.

Also, I am unable to get the height map working with the Displacement channel. I have followed the same steps as in this video:

Can someone please advise me on how to get the Normal and Displacement channels working with the Substance shader? Thank you!

Hello blastframe, set the gamma of your normal map to 1.0. The Image Texture node will default to 2.2.

Hi @jayroth2020, thanks for the reply. There is no Image Texture node. It is the Substance Shader which has no Gamma parameter.

In that case, I would submit a support ticket. I would bet that the normal map is getting a gamma 2.2 applied to it under the hood. The screen capture you showed sure looks that way to me.

Hopefully Ahmet, Beppe, or someone else with OTOY can chime in on the Normal and the Displacement map issues I'm facing.

Hi,
I’m not a Substance user, but I think that you ned this plugin:

It's not a familiar think so please share a sample scene/assets to show what's wrong

The Substance Shader & Engine are native to Cinema 4D. Here is a Maxon Cinema 4D Quick Tip showing how the shader is used:

It is an extremely powerful feature and one that I hope Octane will support very much. It is already currently supported by Redshift and Arnold. The Substance integration allows users to access all of these procedural textures (without having to own Substance Designer):

Here is a scene file demonstrating its current behavior with Octane for Cinema 4D:

Some channels seem to work, but as I mentioned the original post, the Normal map seems to have a different gamma and Octane's Displacement node does not seem to accept the Substance Shader.

Try to compensate for the wrong gamma with a color correction node for the normal map with Gamma 0,45. Does it work?

Thanks for the suggestion. I do know how to fix Gamma issues, I would prefer that the Substance Shader worked as expected.
