The two images in the attached JPEG show the exact same settings under lighting in style editor using the old Warehouse IBL at default settings.
The one on the right is really nice but it instantly turned into the image on the left immediately after I edited a part insert constraint to be up a little higher.
What is going on?
Close the file and reopen it.. Then try it again..
Any raytracing issue I've had (parts not showing up..old parts still showing up even after they are deleted,etc..) has been fixed by just closing the file and reopening it. (maybe even try restarting Inventor if that doesn't fix it)
