Error Unknown property , save me

#1

I didn’t figure out where the mistake of the code was, and I didn’t find the answer in Google.

Who can tell me, save me

I’m going crazy.

	on NEWTEST pressed do ( 

		abc = "name"
		$.material.bac = "name2"
	)

Error: – Unknown property: “bac” in VRayMtl 005:VRayMtl

In MaxScript you can’t create object properties on the fly like that, the material has no “bac” property.

If you are trying to add custom data to the material you can try using custom attributes:
