hello all,

need help for this effect,

i want to the primitive per face on the object, and rotate folowing the color attribute, and i think i got, but got trouble with banking rotate of the face…

i have created template point with match with direction of $PR attribute, and connected onto second input of “ Primitive ” attribute, but seems im still not get the effect

is there any help for me with this, to rotate the face with respect normal direction of the $PR attribute , and effected by color

thanks

one of the simple way is using Transform Axis SOP , you can rotate each primitives based on specify direction (in this case it is N) with this node , So you should just append a For Each SOP for doing this operation for each primitive .
Also to achieve better result you can use T (tangent) instead of N , you can compute T vector simply with PolyFrame SOP .

And this is a simple project about this method , Of course using For Each SOP for complex geometries is so slow , So I think you should use same method in the VEX :idea:
