Hey Juanjo,

As usual thanks so much for all your hard work!! Running into an alpha-channel related issue - while enabling alpha channel still works, I'm unable to get pre-multiplied alpha working. Looks like pre-multiplied alpha toggle isn't having any effect at all in this build.

Hey juanjgon,

Thanks for the hard work on this! There appears to be an issue causing rendering via MPlay to freeze upon either render completion or stopping the render. This is happening with every render, any scene setup. H18.5.351

Note that the Houdini instance is fine, after killing Mplay the ...

Appreciate it juanjgon!

Hey juanjgon,

Just wanted to say thanks for all your work getting fur color working, loving it! We talked a while back about extending Houdini's Vectron support to pull VDBs (either from file or preferably from a VDB node in Houdini's /obj geo context) into Vectron VOPs. I'm guessing this would ...

juanjgon,

Out of curiosity, what's the difference in terms of how the regular Displacement node works vs. vertex displacement? It seems like Vertex Displacement is just doing render-time tessellation and interpolating attrib values? How does the regular Displacement node work differently?

Understood, thanks for the update!

The new Vertex Displacement node does not break attributes. Unfortunately for typical float texture displacement, the Vertex Displacement node is about an order of magnitude slower to achieve similar results.

Attached is a simple example HIP. Basically any displacement fed into a material node breaks any point attributes used in the material. Using a procedural texture in the HIP but this happens with loaded textures as well ...

Hey juanjgon,

Just wanted to check whether you were able to grab that scene file before it expired or if I need to re-upload? Thanks! Again really appreciate all the work you put in for these Houdini plugins!

Couple of ways to do this. Here's a simple one:


- Setup two material nodes - one for your clean metal, one for your rusted metal.
- Plug them both into a material mixer node.
- Plug one of Octane's procedural textures into the amount input of the Material Mixer.
- Voila


For the procedural ...
