I have multiple objects I want to make maps for. They all match up at the edges, so I need the resulting substance maps to flow from one to the others. For the most part they do. However I do want some large scale variation. The sort of thing that is visible across multiple objects, but doesn't tile.
For this I thought using a position map as an input might work well. Unfortunately the position map needs to be normalised by something. Either Bounding Box for the mesh or bounding sphere. These meshes aren't all going to be the same height, so the range for each position map varies, so they don't match up across boundaries.
I want to be able to set fixed values for the max and min range of the map so I can have the range the same for all meshes, regardless of their dimensions.
Is there any way to do this?
At the moment I'm rendering world space gradients in Max, which is an additional step I'd prefer to do away with.
Thanks.
