i want made complex displace shader in vex , i already made a displace shader use bumpnoise in vex ,but i want use cellcrack to add another displace layer,what shall i do ? or i can add another displace shader in obj>geo sop ? thank very much

I don't have a lot of experience with VEX (yet…) but from what I can tell, you can add as many VEX geometry operators in series as you like, but you can have only one VEX displace shader for a piece of geometry. If you want both bumpnoise and cellcrack in the same VEX displace shader, multiply their “amount” outputs together and use this as the “amount” for a Displace Along Normal VOP.

but you might want to add instead of multiply, depending on what kind of look you wanted.
