hi,

which vop node is equivalent of chf() vex function?


thanks!

I don't think there is. Not every VOP has a VEX equivalent function, and vice versa.

The chf() is hscript if im not mistaken. The Lookup chop is the node version of the chf() function. It's functionality can also be replicated with the Blendpose chop.

Oh there is a vex chf() as well. You just have to call it from an Inline VOP as, as said, there is no separate node for it.

It would be good if the gap could be closed if there are any problematic discrepancies, e.g. excluding cases that don't make sense to be in one or the other.

I agree. I submitted individual ones and one to equalize both long ago. Unfortunately there are too many. For instance the geometry inspection functions like vertexpoint, pointvertex, primvertex, etc are not available as VOPs .

IMO the best solution is to go through each VOP and VEX function and add them to the other if it's missing. After that any new VOP or VEX function should always be added to both. Otherwise we are forced to use one over the other by artificial constraints.

I don't think this is high on SESI's to-do list though

There are also other limitations that further divides them up:

1. You can't define structs in AttribWrangle SOP but you can in AttribVOP SOP.

2. You can't define a function that returns an array in AttribWrangle SOP but you can in AttribVOP SOP.

All these issues cause many hours to be wasted and lost productivity. This is only for 1 person. Multiply it with 100, then it becomes a huge problem IMO.

It also makes teaching/training very hard.

I agree. Many inconsistent rules to confuse me!
