After watching a SubstanceDesigner Video on Youtube, i thought this should even be possible in houdini.
So i layed down a principle shader core and connected the brick pattern. With id output and uv i tried to feed a for each to populate a ramp in to the single bricks, but i got stuck and cause i am a beginner with shader creation in Houdini i dont know where to go from now.
Can sonebody point me in the right direction?

Ohhh and for better understanding what I am after, here is the Brick creation Video.

I checked this brick video: https://www.youtube.com/watch?v=bpsLg44gSg8 [www.youtube.com]
In houdini you need a lot more nodes to get to the same result.
The difference between substance and a houdini shader is that substance can also use 2d effects like blur and stamping.
You could replicate those effects in a shader, but it is a lot of work and can get slow.
I made an example where I use the brick pattern and gave them random rotation and a random ramp per brick.
You could add noise to try to get close to result in the video, but to get that exact look will be hard to do.

thx Arjan. and yeah that was the video, seems i forgot to link it..

i have tested a lot the last days, mostly with box tile and stripes, but yes your right, everything gets very slow when using noises and the node graph gets very messy and confusing.

if it takes ages to create such stuff I think I have to go with substance or the way alexander.artwork shows here

using cops to create the texture maps and feed that into the shader.

anyway. thx arjan
