Displacement octane houdini

[philippecounter]

Hello everyone ! I can’t figure how to use displacement in octane for houdini.
The vertex displacement node works well, but the displacement node don’t…

The conventional displacement only works over UV mapped objects, and only from texture files. It is not compatible with projection nodes, or procedurals or even texture processing nodes, although you can use the baked image tool to rasterize them.

Hope it helps,

The vertex displacement map doesn't require baking, correct ?

What made OToy release the vertex displacement option ?

[juanjgon]

The vertex displacement is based on the mesh subdivision at the scene preprocessing time, creating a more dense mesh with a lot more polygons (this is the displacement technology found in near all other renderers). The conventional displacement is a render-time effect that doesn't increase the mesh complexity but it has several limitations. This is why Octane has both subdivision technologies.

Thanks,
