Use Background Shader equivalent

[Craig3d]

Hi Guys I forgot to ask 2 questions in the last post.

Im running maya 2016 with the latest Octane Plugin.

I have searched for this in the forum.

Do we have a Use Background Shader equivalent (eg. shadow matte) ?

Can Octane subdivide my mesh at render time?

Kind Regards

[Craig3d]

ok cool.

I see that you just need to enable Matte on the diffuse material to get the matte

Any ides on the subdividing?

Thanks again

Yes it can. It is on the shape node just below where you select how you want it to render (movable proxy, full or deformable)

Don't get as excited as I did. Matte is not what you think. It still picks up shadow from those objects. It's not the matte that you and I are looking for.

[Wenneker]

I would like something that works as the diffuse matte option but with a glossy material. I want to be able to get the reflections of an object on an invisible plane.
What are you looking for?

Yup, the excitement was pretty much instantly deflated here too. Relatively new to Octane (from VRay ) and banging my head on the wall trying to knock out clean mattes (ie without shadows.)

[Wenneker]

aah right If I understand you want to use these for masking and you're looking for an equivalent of the multi-matte pass in vray?
This to me isn't such a big, most of the time a separate render with just surface-shaders / light materials renders fast enough. Although I would think this shouldn't be to hard to implement. Since it's already rendering an object pass material-id's shouldn't be to different. If only you could render only selected objects/materials to a pass to avoid aliasing problems.
