I'm using SD to make rock materials and I'd like to generate a mesh that matches the material. Is it possible to use a Substance height map output to displace a plane in a model graph? Seems like a common need but I can't seem to find a way to do this.
It is currently not possible to use bitmaps to drive a input in a Substance model graph.
That being said, you can export a displaced mesh out of the 3D view and use it as an input in a Substance model graph. You can learn more about using custom meshes in Substance model graphs here and here.
The current implementation of the feature uses OpenGL and was not stable enough on macOS for public release. We may revisit this in the future as graphics technology on macOS systems advance, but have no plans to share at this point in time.
We do have plans however for bitmap-driven displacement – and other uses of bitmaps – in Substance model graphs, but again no plans to share currently. We have barely scratched the surface of what we want to do with Substance models, stay tuned!
