Hello, is it possible to use the xform vop to scale an object uniformly, while keeping its position (pivot)?

I've tried doing it in vex and with a transform node, but neither worked.

The transform node would have worked, except you can't drive the uniform scale parameter with an attribute.

This is what it would look like with a transform node (except you cant use a custom attribute for uniform scale).

I tried doing that and it just turns green and stays at 0. My scale attribute is updating each frame so I guess that's why it doesn't work?

So it seems to be something with my attribute being a point attribute. I tried filling it in the transform like your detail attribute example, but it doesn't like the syntax.

try `point(0,0,'final',0)`
because `point` need point number, `detail` do not required
