I've tied displacement in Revit as well an what I've found out is that it works, but it seems to be impossible to adjust the depth of displacement in reasonable way. Anything I got was extremely deep. I had thought it should go from minimal amount at 500 at Revit's bump map slider to some extreme at 1000. I wasn't able, however, to generate credible visualisation of brick wall with i.e. 5mm deep grouts.
Am I doing something wrong?
