kaom, You can set the U and V Samples to any number up to the limits of your system's memory. AGr will try to do as much as it can. If it runs out of memory, it will just return the original mesh with no deformation. U and V don't impact the scaling of the shader, it's just the number of samples it will use across the object's UV space.
