Dear Alex,

when dealing with parallel (mostly identical) pipelines (x7) and several Construct Surface Mesh modifiers (x3 per pipeline), OVITO seems to get stuck in a loop in one pipeline (status bar shows Constructing surface mesh... several times per second). Sometimes I get this SEGFAULT, although it may be two separate problems with this modifier. Although it does happen during playback, it never happens while rendering.

Best regards, Arkadii
