I am using a musgrave texture and I wanted to apply a low pass filter on fac output, and use it as a displacement in the displacement input of the Material output. I tried the math section but (EDIT)I did not get. Kindly help.
Edit: I added two Diffuse BSDF's with slightly different colors and wanted to filter the musgrave texture to have only low passed values which go into displacement node and then to displacement input of the material,they also go into fac input of mix shader.
