Reversing normals with center of a primitive

Recommended Posts

Hey Guys! 

I have those wonderful walls going through a for each loop and some of my normals and faces are reversed at the end.

I was thinking about getting the center of each prim and use a wrangle to reverse the normals but not quite sure how to approach that.

Thanks for the help.

i have bang my head a lot with some shitty mesh coming from C4D. the most effective way i found,  that work more than 95% of the time was to. 

loop each pieces, close them, convert to vdb then compare N with Grad and invert the direction if they are not the same. 

it might work in your case.
