How to define a CurveProfile property?

Hi!
This commit (https://developer.blender.org/rBba1e9ae4733ae956331c7e8899f6939997205298)
added the CurveProfile type (https://docs.blender.org/api/2.82/bpy.types.CurveProfile.html?highlight=curveprofile) but how to define a property (of a Operator) as a CurveProfile type to be added in a python addon?

I wish there were a way right now to do this, but unfortunately I don’t think there is.

How do you add custom profile prop to operator (like in bevel operator)

I tried to create pointerProp type=bpy.types.CurveProfile (not sure why I shoudl create subclass for it?), but blender would not register this kind of operator property. Now I tried to use bevel_curve_profile directly in operator draw function: layout.template_curveprofile(context.tool_settings, “custom_bevel_profile_preset”) but any changes to curve are gone on operator redo: It was the same with curve-mapping node in past. I guess operator is undoing any changes to objects, scene, pro…

The hack with CurveMapping is to use a node group with it inside, but there is no node with a CurveProfile in it.

I will try to make this possible, but I’m not exactly sure how, so it will depend on the help of other developers and honestly this is sort of low priority compared to other stuff I guess.

Probably the same situation as with bpy.types.CurveMapping and bpy.types.ColorRamp, all of which are not possible to create from the Python API.

It’s quite depressing.

It’s a hack, but you may find it somehow useful

How do you add custom profile prop to operator (like in bevel operator)

If you don’t mind the fact that it’s a dirty hack, add Bevel modifier to an object you’ll run your operator on(turn modifier off so you won’t see bevel applied), check custom profile, from here you can edit profile and it won’t get reset if you change other operator’s properties. To update profile in operator’s window you have to hover cursor over it. This way you can have Profile widget even as a node property. [image]
