Material Displacement

[Krotus]

Hello Everyone!

I’ve been trying to create a material that takes advantage of the new Displacement option. There are 2 options to control the displacement: Magnitude and Center:

Does anyone know how to get at these to make them parameters for the material?

Also, I can use a material instance and make adjustments here in the master material and see the results on screen. But when I try to make adjustments to the same parameters in the material instance by enabling Displacement Scaling in the Material Property Overrides section, they do not affect the material at all:

Is anyone else running into the same issue?

For the magnitude you can make a scalar parameter (call it “magnitude”) and multiply it with the displacement map.

For the center this should be set according to the type of displacement map you are using. For a map with a 0-1 range (a png or jpg) the center is 0.5, for a floating point image like EXR which can go into negative values, the center is 0. You would not adjust this in the material instance. For displacement you ideally want to use EXR as it can hold more detail.
