This entire article would be discussing the ‘Vray Displacement modifier’.īefore we start using the modifier, let me explain the important parameters. One important thing, which I would like to mention before going further is, the vray displacement is not visible in viewport. The concept is very similar to the bump mapping system, though bump mapping only is a shading effect that changes the appearance of the mesh or model.

Displacement mapping is a technique for adding detail to your scene geometry without having to model it first. Like we discussed before, displacement actually changes the geometry of the object during the render process. Filter texmap should be unchecked, I don't have that checked generally so ignore that.In the last article we overviewed displacement in Mental ray. Here the model was scaled by element inside edit poly, the amount is at the default 100cm again. Here I've lowered the amount to 50cm from 100cm. This shows what happens when I shrink the whole object and apply the same 32bit displacement map (in. This image shows the full-size object with the displacement map applied. Is there some way to avoid the issue of exploding meshes when you scale them down with vraydisplacementmod or do I need to change to a 16bit displacement map? I know there is a scale slider when you export a displacement map in zbrush, but I thought they were only for 16bit maps and I'm using a 32bit one. I've tried exporting a scaled down version of the object from zbrush as well with no improvements. Sometimes the model looks unaffected, very exploded or parts of it will be okay while other parts are unaffected. I tried lowering the amount and the shift amount with very random results. I've tried resetting the x-form with no improvement. When use the scaling tool, the mesh explodes when I apply the displacement map. I then noticed that my object was a bit too large and I needed to scale it down. I rendered it and everything works as expected. I set it to '2d mapping (landscape)' I leave the Amount set to the default of '100cm' and shift '0cm'. I rendered out a 32bit displacement map from zbrush and imported the object into 3dsm and applied vraydisplacementmod to the object.
