I want to parametrically control tiling of entire material (using the green noodles). There used to be option for this. If I use Material Transform node I cannot see tiling option. There is Stretch and Rotation that I obviously don't want. I can eyeball scale of the transform but cannot see how I could tile the material parametrically so that it stays seamless.
To easily adjust tiling using a Material Transform node, you can use the x2 and /2 buttons under the Stretch section of the Transformation parameter. These buttons scale the textures to exactly 200% and 50% of their previous size respectively.
If you need to control this effect using a simple exposed integer parameter, you can use a function to drive the Transformation parameter's matrix values .
Scaling the textures to exactly power of two increments (50%, 100%, 200%, 400%...) is equal to applying a power of two to the X and W components of the transformation matrix (X, Y, Z, W) such as (2^tiling, 0, 0, 2^tiling).
I hope this is helpful!
Thank you, much appreciated!
I am happy to help!
