You can now blend up to 16 MtlX Standard Surface VOPs or MtlX OpenPBR Surface VOPs through MtlX Mix VOPs. In previous versions, blending was limited to two shaders.

you can also use RMB/Reference/Scene Data... to link any parameter to an attribute without typing the expressions manually, especially handy for something like position where you have to link 3 parameters

on top of mismatched brackets, you are also not using the correct form of point() function, since hscript [www.sidefx.com] and vex [www.sidefx.com] versions expect different arguments

try this one
