VectorCurves Node in SubstanceDesigner?

[luciand67129654]

Hello everyone,

How can I easily replicate the VectorCurves node from blender in substance?

I basically want to obtain an easy parameter for changing the shape of a GradientRadial node.

So far I only found with other shapes and masks.

Thank you

The closest thing you got is the built-in curve node, which is only able to remap a grayscale input. For more complex logic you'd have to get into the Pixel Processor and function graphs.

Hello,

From what I am seeing in the screenshot you shared, the deformation is achieved by remapping UVs using a curve.

Ole is right: you may use the Curve node to drive a deformation.

We manually build a UV map, adjust it using a Curve node then feed the result to a UV mapper node to drive the deformation. Thusly: 

Linear gradients are combined using a RGBA Merge node to create the UV map where U and V are mapped to Red and Green respectively.
The Curve node is used to remap UVs in the green channel for a vertical deformation.

I hope this is helpful !

Best regards.
