TriPlanar Displacment

[MagnusL3D]

Hello,

Is it a limitation of the Houdini Plugin (3.08.1) that you can not use the TriPlanar result of a displacment texture as a input to the Displacment node or is it just a octane thing ? I do this all the time in Mantra / Arnold / RS so I am a bit supprised.

Hi,

Yes, sorry, currently the displacement in Octane only works with the texture image nodes over UV mapped objects. No other node is compatible with this feature.

Thanks,

Aha thank you for respone. Is this something that they will fix in v4 ?

[juanjgon]

I'm not sure, sorry. Improving the displacement is a planned feature, but don't know if it is going to be compatible with additional shader nodes.

Thanks,

Thanks Juanjo,

I have a follow up question. Is there anyway inside Houdini to blend 2 displacement texture together (with octane as renderer) ? I have tried adding and the mix node and some other methods but the only things that seems to work is if I take a 'image' node directly into the displacement node.

[juanjgon]

Nope, sorry. Currently, the texture image nodes over a UV mapped mesh is the only way to render displacement in Octane. If you want to blend two textures, you are going to need to blend them before use the final texture for displacement.

Thanks,

Yeah I was afraid of that, because that means I can't have curvature / ao etc to drive the blending. But still, good to know that I didn't miss something =)
