Hello. I used a WIP Bmesh version from said period to do a scene. Unfortunately, the scene crashes offical builds whwn I open it. I tried two builds from graphicall : One was apparently too late ( Feb 2012) as it crashes the other ( May 2011) too early as it distorts all objects in the scene. Does anyone know where I can find a compatible build ? Does the .blend file contain infos regarding the used software revision?
