Hi,

I have a carton created with two groups in the shader tree that have separate image map (set as a group mask), materials and bump maps. Both materials are metallic but are next to one another. I have the same alpha mask being used in each group but inverted to each other.

The octane plug in doesn't seem to recognize this. How would I go about setting this up with the plugin?

Thanks

Hi - can you give us some more details pls? Either a scene showing the issue (preferred option), or a screenshot of the Modo Shader Tree? What version of Modo and the plugin are you running pls?

Hi Paul. Should have known better than to be so vague. I've attached some images for you.

Running Modo 801 SP3 on Windows 8 (64) with 2.16.0.48 plug in. The mask is a png file.

Does the plugin recognize group masks like this or is there a better way to handle?

Thanks for the help.

Group Mask is not supported, however Layer Mask is - so you should be able to get the same effect that way.

Tried changing it with Layer Masks and still don't see any change in Octane.

Any other workaround that you know of? How would you do this in Octane Standalone?

Set the layer mask up as per below, and the Octane plugin will render it correctly. I think in your example the Modo procedural textures will be being ignored (the Ripples and Dimples).

This was introduced in 2.15.0.46.
- Added support for the Layer Mask effect. This only works when the Layer Mask is applied to a Image in the Shader Tree, and only works with Constant and Image nodes above the Layer Mask with an effect of Diffuse Color

If you want to see how this is working inside Octane, set up as per below, then add an Octane Override for the material, and you will see the node layout.

Is there any way of using more than one layer mask in a single "stack"? Let's say you'd like to combine 3 or 4 textures on a single object, using layer masks (but using only 2 uv channels, one for the textures, the other for the masks)

Nevermind, it's possible within the octane override, quite easily.
Almost every Octane-related issue resolves itself within minutes after posting here, most because of Paul's advice, but some simply resolve themselves apparently...
