[227i][Software]Static mesh crashing with mirror surfaces
Sep 8th, 2017 at 7:04pm
Print Post  
When using the software rendering mode, and a static mesh is contacting a mirrored BSP surface whilst in view, the game (or editor with realtime preview enabled) may crash.

In order for this to occur, a surface of the static mesh must be on the same plane as the mirrored surface and intersect the surface. The crash happens in any RMODE except Wireframe. It may not crash straight away, but changing the viewing angle will make it happen.

Below is a log of the crash experienced:

Below is an example setup that causes this crash. The box is a static mesh with its bottom surface touching the floor of the room, which has the mirror flag set.

Thanks for reporting, going to try this with latest build (and fix if necessary).

Sometimes you have to lose a fight to win the war.
