Displacement Map

[nathanpeucker]

Hey guys,

 

Recently started tackling V-Ray. Curious about displacement maps.

 

I'm trying to add texture to a rendered-brick-esque material through displacement and bump maps. I'm using the stock 3ds max stucco map for both.

 

However when I do, it seems the faces are actually displaced from the surface, leaving gaps where connected edges should be.

 

I'm trying to do this without the DisplacementMod (which I know works with Keep Continuity) as I don't want the whole geometry displaced, just certain faces with the respective material.

 

Any insight would be appreciated! Thanks

 

EDIT: I'm referring to the darker texture, admittedly the gaps are subtle in this example, but they're there!

Hi! Might be because of high amount of displacement value you put. IMO, if the bricks are not too close to the view, i'll use bump rather than displacement.

You could try combining a vrayedgetex map with your displacement map in a composite map so the edges stay in place. Otherwise you should unwrap your geometry using a UnwrapUVW modifier and paint your displacement where it needs to go on your geometry.

A quick dirty solution is to invert your disp map and use a negative displacement.
