Gradients & Weight Maps

[lightvu]

Is it possible to use vertex maps (weight maps) &/or the gradients available in Modo somehow with Octane?
Coming from Octane for LightWave I always thought it would be amazing to use a weight map to control the blending of two materials.

Is this just a dream or can it be accomplished?

Thanks for any feedback

Gradients are already supported (https://docs.otoy.com/ModoH/ModoPluginM ... exture.htm). I think weight maps would be difficult to support, since it's a value at the vertex level which would be hard to translate back to a material. You can however use the Falloff Map node, which may achieve what you are trying to do.

That looks very close to what I need.
Is that an incidence angle gradient?
What type of inputs does it accept? Even if you can just tell me which nodes it accepts I can take it from there

And if I have your attention right now I am wondering if it's possible to use any function from Modo like the layers in the shading tree (such as procedural layers) in Octane.
I'm pretty sure I couldn't in LightWave but I am wondering if that's true in Modo too.

Finally how would it be possible (even a workaround) to use the sculpting capabilities in Modo to my advantage with Octane rendering.

Sorry for the barrage of information here, but those are 3 questions I would really appreciate an answer to

Thanks Paul.

You can bake anything in MODO and use it in Octane as an image node. It would be better to have a sort of 'rasterinzing' node that can bake any procedurals live...and feed the data into Octane (modo, v-ray, prorender, whatever). I *thought* they were doing that with ProRender but I'm not so sure.

Here's some MODO | Octane videos to look at.

Check the Standalone manual for details - https://docs.otoy.com/StandaloneH_STA/S ... adient.htm.

Yes, there is some support for layers - pls see the manual. https://docs.otoy.com/ModoH/ModoPluginM ... rMasks.htm

Sorry - I'm not sure what you mean by "sculpting capabilities".

Thanks

K so I have re-read this thread after feeling much more comfortable in both Modo & Octane.

It would be great to use a weight map to control the blending of 2 Octane materials, but if this isn't possible, how can I bake a weight map into a surface?

Vertex attributes (from Modo Mesh weight maps and RGB/RGBA maps) are supported in the Octane 2018.1 version of the plugin, which should be available in the next week or so.

Oh that is great news!

In regards to the original post, can someone tell me what I am doing wrong in this scene?

The zip has a very simple modo file and V.png

thanks

That scene rendered OK for me. You didn't say what problem you are having.
