Recreating chipped concrete edges via shader

V-Ray for Rhino V-Ray for Rhino :: General
1

Hi everyone,

I’m trying to recreate this chipped/broken concrete edge effect in Rhino + V-Ray, mainly via shader/material setup rather than modeling it manually.

The reference image is a 3D render, probably made with 3ds Max + Corona.

Is there a good way to achieve this in V-Ray for Rhino using displacement or similar shader-based techniques?

Thanks

Hi @michel_verliefden ,

There is a way for this to be set up procedurally but it requires a bit of shader work and testing to get all the values just right.

Here’s the logic that can be used.

1) Create a Curvature map - it will produce a white color where the edges of the slab are.

2) Mix it with a Noise texture to break it up.

3) Remap the result using a curve to invert and make it sharper.

4) Multiply on top of the existing bump map and possibly the diffuse.

5) Add an additional Bump modifier to the material to round the corners

And here’s the result:

The sizes and radiuses of all textures will have to be adjusted to match your scene size.

Hi @konstantin_chaos ,
thanks for your answer.
will it be possible for you to share the material you create in Rhino ?
it will be more easy for me to see and understand all the settings you had to do.

thanks a lot in advance.
kind regards,

thomas
