True Displacement Disabled vs Bump

Recommended Posts

I'm curious about the displacement vs the bump settings in Houdini's principled and mantra surface shaders.  Is there any difference between bump and displacement with 'True Displacements' unchecked?

in terms of what they do, no

they both just alter the normals, you can however use both and bump/normal map will be applied on top of displacement normals, since internally, exported displacement normal alters surface normal and that is later altered with bump/normal  map

Thanks for that! That's what I figured, and what I'd seen in the network - but I'm not a smart man, so I like to check these things..

Cheers!
