Windows 10 64 bits
The issue is not with the rendering but just in case: Iris Pro graphics with Nvidia 960M
Broken: 2.78c e92f235283
Short description of error
Sometimes when applying the boolean modifier, selecting Difference does a Union and conversly.
Exact steps for others to reproduce the error
- Open attached Blender file
- Select Primary white bishop
- Add Boolean Modifier (Difference, BMesh, Object: Cube)
At this point a Union was made instead of a Difference. If selecting Union it makes a Difference instead.
EDIT: when doing a Difference by selecting Union, faces to "cover the holes" are not created like they're supposed to be
It seems like deleting the cube and trying with a fresh one corrects the error.
