Displacement

[Robert]

I can't get displacement to work. Is there some special channel, etc?

There are special texture effects for displacement/bump/normal mapping. When you right-click on a texture's effect, these are under Surface Shading.
When using one of V-Ray's materials, the displacement/bump amounts can be found under the "Texture Layers" tab. Doesn't sound intuitive, but it is
a common place, so once you know they are there, it is easy to find for each material.

If you want more fine control over the displacement, you can add the V-Ray Geometry Properties to the mesh item.
Note that the displacement amount, displacement shift and water level in the V-Ray Geometry Properties will be multiplied by the displacement amount from the material.

MODO 801 also has additional channels on the material item called bump/displacement/stencil value. I think these are meant for schematic connections.
We don't support them yet, but we will soon, hopefully.

Also changes to displacement are not picked-up in RT right for now.

Displacement values seems a bit difficult to understand. Attached herewith I have a plane with a vray geometry properties applied to it. I want a 30mm thickness to the cutout plane.
It renders as a single face...untill I push the displacement to 300mm. But, adding a watermark it still works on 2mm.
I am sure the displacement value should work on 30mm? There seems to be a 0 too much in the values?

The displacement amount is the amount of displacement, where the displacement texture is completely white. So, if your texture's brightest color is 1/10 of white, you will get a maximum displacement of 30mm with the displacement amount set to 300mm.
The water level on the other hand will always cut-off 2mm from that.
By the way, the 2d displacement mode seems much better for this kind of displacement (with sharp changes in the texture's values).
