Title: Brick Material Shader
Post by: ChrisMyatt on 2019-09-22, 14:01:32

Hi there,

I'm looking for some advice, tips on a way to produce a shader that replicates the following Reference. It is a brick that has one chiseled face. It's for a personal animation project i am looking to do, which will involve one shot of the sunlight rotating round the eliptical facade to show off this chiseled detail.

Therefore i need the bricks to be each unique.

i was hoping to use a selection tag to displace one face and use the variation effect to create variation in the UVW noise so that each displaced face is unique. However, it produced an undesirable result pulling the displaced face away from the rest of the brick, which makes sense.

Second try was splitting the displaced face away from the rest of the model and closing the hole. I think moved this face inside the brick so that the displacement would look as if it came from the brick. However it just seems a little messy, i feel like there could be a better way to create this.

Thanks in advance. I've attached a basic scene, with what i have so far. Feel free to play with it.

I'd use a cloner to distribute the bricks and a noise shader in world mode to get the variations in displacement.

I simply changed the noises to world here.
