My plugin suite uses a plugin hierarchy deformer to deform the root polygon mesh. It seems that when editing the mesh points/edges/polygons, there is a chance of crashing C4D. The crash occurs in ModifyObject(). I've checked (and rechecked, twice) and there is not one memory pointer that isn't accounted for, even the arguments are checked. There are only three methods called during the process (when editing) : Draw(), CheckDirty(), and ModifyObject().

When and how it occurs is not reproducable so far. Sometimes it's just moving the points, sometimes it's the undo after moving them, sometimes it's the moving after undoing a move. Sometimes it happens right away, sometimes it doesn't happen at all.

Any ideas, suggestions, caveats?

Thanks,

Robert

Howdy,

Well, I don't know if this applies, but is the polygon mesh also in a HyperNURBS?

I had some trouble with getting proper point count when the object was in a HyperNURBS, it was unpredictable because sometimes the point count of the HyperNURBS object would be returned. So, then as I looped through the points array's indeces it would get to the end of the points array, but still try to keep going, and you know for sure it would crash then.

It has something to do with the timing of when GetPointCount() is called. Or, something like that. Here's the thread I posted:

Adios,

Hey Dan,

Definitely not related to HN. It happens with just the base Polygon object - as long as my hierarchy modifier bones are underneath. Still cannot reproduce a single instance - it just occurs at random some time, some place during editing or undoing. If the hierarchy is moved out from underneath the Polygon object, it never crashes.

Thanks,
