Is it possible to change U Tiling property of material outside of the editor (with rules or custom script)?
Yes, there are a few ways to accomplish this.
First, create a TilingOverride operator on the material.
Then, create a Number Attribute & a rule that sets the UTile Property
Finally, create an attribute with the same name on the model referencing the material. To update the tiling, you simply setConfiguration Model’s UTile Attribute.
