probably box mapping would do the trick here. One caveat is it’s not as fully featured as native texture mapping in Rhino, and it only works with meshes. If you feed that wall into a Box Mapping component, feed it a box that’s the size of your texture image, you can take the resulting mesh into the “custom preview materials” component from Human, or bake it for use with v-ray (the texture mapping should be preserved if you bake that mesh.)
You can ask if @gankeyu has something among his components, because some time ago, he was very kind to investigate this limitation (texture mapping of GH objects). The limitation which in my opinion is worth being fully resolved - for example for VisualARQ GH Styles.
Thanks. I will add that part. Generally it’s copy everything into Grasshopper’s Component folder (File -> Special Folders -> Component), and unblock the gha file (right-click the gha file -> Properties -> Unblock -> OK).
You can leave out Pancake.resources.dll as it’s for other language interface.
Human preview only supports the diffuse texture channel (and an alpha channel). You can also pick existing materials in your rhino document with the normal “Custom preview” component, with all the complexities of those textures. This should respect the mappings from Human.
Thx for the response. Yes GH preview, materials, Human Preview, Textures. Is there a way to COMBINE a material with a texture like you would with layers in photoshop for example. Grey steel material + scratches texture ?
