3DsMax Vray 6 Update 1.2 broken? This issue is not to do with the renderer at all. It seems when you are exporting an alembic scene from 3ds Max, that the alembic has changed the up direction to what we are expecting in HDR Light Studio. I wonder if you have changed your default alembic settings when exporting, or maybe you have changed the up direction for 3DS Max?
Its all about the up direction for the scene and when this is exported into HDR Light Studio, the up direction is wrong. I wonder if you can check if you have been changing the up direction somewhere?
