Hello,i wrote a xpresso node to write converted C4D-Geometry in the geo-file-format. The node works fine and the node only executes if, the geometry is "dirty" (dirtycount has changed). Now my problem. If the frame changes, the system crashs.
At the moment i don't understand the context between the operations in the Calculation-method and the timeline. Is every frame treated like a own scene or "instance" and so i need for every frame a new thread and have to synchronize them???Thanks,

To write the data in the geo-file, i use the C++-STL ofstream instead of the hyperflile class.
Could this cause the crash?cheers,

Are you writing files during realtime playback?
Also if possible post some simplified code.

It should write during realtime playback (to save whole sequences) or after manual frame change.

One additional question.
What is the ident-parameter in the hyperfile Open-method and what have i to declare?cheers,

New approach.
I use now the Cinema4D-BaseFile to write the geo-file. As i thought, the STL causes the crash. So far so godd, but now i have an new problem.
In one line of the geo-file Cinema writes a number previous to the entry.> <code>

PGEOMETRY V5
NPoints 8 NPrims 6
NPointGroups 0 NPrimGroups 0
8NPointAttrib 0 NVertexAttrib 0 NPrimAttrib 0 NAttrib 1
Why is there number 8 in front of NPointAttrib

To write ASCII text files I usally use my own WriteString function since the BaseFile::WriteString() seems a bit strange to me.

Now i have nearly the same problem as before. But now i can change the frame on teh timeline between 3 and 11 times before the system crahs.
I thought it crahs during the calculation. But the node calculates and writes a "perfect" geo-file and then the system cashs.
Any ideas?cheers,

Sorry, I had not the time yet to dig deeper into it. Does this only happen from within a XPresso node? What about expressions or generators? This may be something to look into. I will try to find a solution but I have to discuss this with our developers.

It happens only in this XPresso Node. The other nodes works fine if i change the frame on the timeline. My generator works too.
Thanking you in anticipation,

Ok, I tried to confirm this. I am not sure if the problem is really in the node. Here is the code of a simple node that writes out geometry of a polygon object. It seems to work fine without any crashes. Maybe this helps.

Thanks Matthias,
i got it. But it is realy awkward :-).
I allocate a LONG-array to save the polygoninformation temporarily.
And there was the problem.
