My friend and I are trying to understand how a displacement map affect a model in UE4. We didn’t find anything deep enough to truly understand how the World Displacement works in UE4.
In 3DMAX, 50% gray is zero, so we can have negative displacement. But, in our test, it seems that in UE4, black is zero displacement. Is there a way to use the same displacement map we had generated in 3DMAX? We’ve tried to change the contrast of the image, but what color does the black should turn? It can’t be black.
Also, it seems that it isn’t a linear displacement. In our test (attached image) we used a multiplier 6 and the colors white 100%, gray 50% and black 0%, we could notice that the white map with the black and gray details creates almost the same distortion. Shouldn’t the black detail create a “hole” bigger than the gray detail?
Can anyone help us, please?
Thank you very much!
