Geometry Nodes: Transfer attributes in the curve to mesh node This patch allows point and spline attributes to be transferred to the mesh generated by the curve to mesh node. All dynamic named and anonymous attributes are transferred. So a user-created attribute will be transferred, but "radius", "tilt" or the handle position attributes won't be transferred by default and will need to be copied first. This trade-off is made for performance, since most of the time, users won't need these attributes copied. Generally, attributes are transferred to the point/vertex domain. However, if they have the same name as a built-in mesh attribute that only exists on a different domain, like "shade_smooth", then they can be transferred directly to that domain as well. Conversion directly to the face corner domain is not necessary because there are no builtin face corner attributes. I see this conversion directly to other domains as an optimization we could use behind the scenes in the future as well, when named attributes are less common. For performance, I haven't tested which of the following is better: ``` for each spline combination: for each attribute: for each attribute: for each spline combination: ``` For now I used the existing loop to avoid more threading overhead.
