Hi,
Is there a global variable to center the pivot on a UV transform sop which is is transforming a bunch of vertices in the UV editor .

Rob

I don't think there is. I asked for an RFE for this exact same thing recently. CEX, CEY, CEZ is only for geometry.

I will email them for a RFE aswell .

is using a point sop to convert your UVs temporarily into 3d geometry an option (swizzling the TX, TY, TZ with MAPU, MAPV, and MAPW?) A lot of times I do this if I need access to geometry operations that may not be available for UV parameters. I think you may be able to use this to find the centroid of a group for the purposes of feeding it into a transformation

BTW, wonder if this may be your solution…

Houdini 12.1.36: Overrode $CE, $MIN, $MAX, and $SIZE local variables for the UVTransform SOP and fixed a bug computing the bounding box of a vertex attribute.

Thats the awesomeness of having support !

I didn't know they added that. Thanks Gray and SESI.
