Sun + Sky + Vray Clipper mesh

Has anyone else had issues using Vray Sun and Sky and A clipper mesh? Im getting an unhandled exception c0000005 error whenever I try to RT. Itll try to do one RT pass and then crash.

Using clip mesh, Substraction, and a select set in the Exclude input.

Maya 2018. Vray 3.6

If I disable the clipper, the shot renders fine in RT.

Seems it was crashing with any new lights. I deleted the clipper mesh, exported as an obj, brought back in and rebuilt all the connections. Seems to be going a bit smoother.

Buggy clipper mesh. Rebuilt and Sun+Sky is working again too. False alarm!
