Line MAT and width for instances

General TouchDesigner Discussion

I love me some line MAT these days, but I’ve been trying to figure out if there’s a clean way to take advantage of the ability to pass a width attribute to lines when working with instances.

I know how to do this with SOPs:

Working with point attributes, stamps, and the like:

But my question is… is it possible to access that width attribute with instances and not only through sops.

EDIT:

As a follow-up, I know there are some handles for this with respect to the near and far width pars, but I’m really after a more direct handle for controlling the width attributes :slight_smile:

Are you looking to have a different width per-point of each instance? If so, I don’t think that fits into the realm of instances as you get to affect the transform / color of each whole instance, but not parts of an instance.

I thought about that - and while that’s very tempting, what I’m after in this case is width per instance.

No, sorry, it’s not exposed via a parameter on the Instance pages.
