You are going to want to try a Rivit. Then you can put the light under the locator it creates.Rivit should be under the constrain menu but I can't remember if that's were it was in 2018
Hi,
Thanks for this solution ! i have maya 2018, and it don't exit. i'll try to update my maya and keep you in touch, thanks !
So your idea work with the constraint " point on poly" in maya 2018. And it work only with an Arnold meshlight, not with area light, but it's enough for me, so thanks so much for your help !
Peace
Wait. Yes you should be able to do what you are trying to do. If you Point On Poly a locator with maintain offset off and then parent the light to the locator it should work. So maybe give that a try.
