OctaneRender 4.02 for Houdini Production build 4.02.1.1 Tweet

[juanjgon]

hello.
Null node in Octane Network doesnt working.

Nope, sorry, the null VOP is available to support some internal Houdini features, but currently, it can't be used in the shader networks. I'll try to add this feature for the next Octane 2018/2019 plugin build.

Thanks for reporting this limitation!

Hmm, I think that Octane doesn't have a tool to only invert one component, but I'm thinking that probably you could write a very simple OSL texture with this feature.

Hope it helps,

It is a pity that I don't know how to work with OSL

Sorry, I'm afraid that the mesh custom attributes feature has been added in the Octane 2018.1 version. It is not available in Octane 4.

Sorry, my mistake. I'm afraid that currently the final OSL VOP nodes with exposed inputs are available in the 2018.1 plugin builds only. The changes made in the plugin code to support this feature were done along the 2018.1 development cycle and they are too complex to commit them back into the 4.02 plugin branch.

As you can see in the attached image, your OSL shader works fine in Octane 2018.1 ... not sure if you have access to it to test it there.
