I create an otl in “vex builder type” so its instance is a vex node. A ramp parameter is added on this vex node via type properties parameters pane. On this pane, the “VEX Ramp Variable”: ‘Basis Name’, ‘Keys Name’ and ‘Values Name’ is assgned. How do I accessing this ramp basis, keys, vals inside inner vex code??

I am having undefined variable error while compile??
please help !!

It appears that “VEX Ramp Variables” are used only for Shop HDAs. These variables become tags on a shop node that later get used when building a shader string in SOHO (see ‘rampbasis_var’ in shopclerks/clerkutil.py).

I don't think you can use them for a Vop HDA.



P.S.
submitted RFE 52158 for his.

rafal, thank you for sbmitted as RFE, I will have look the py file you mention. Big Thanks
