Hi,
in my expression tag, I have a function to record keyframes... it gets global position and rotation, as well as other attributes, from the camera object the tag is attached to, and stores them in keyframes for another camera object.
Some users (they all use Win32) experience a crash immediately when using that function. The problem is: whatever I do, I can't reproduce that crash. It just runs perfectly on my computer. Tested in R10.1 and R10.5, no difference.
Here's my code of the recording function:
> <code> Vector GlobalPos = op->GetMg().off;
> Vector GlobalRot = MatrixToHPB(op->GetMg());
> SC_RecorderCam->SetMg(op->GetMg());
> if (SC_FocusEnabled)
> {
> SC_RecorderCam->GetDataInstance()->SetBool(CAMERAOBJECT_FRONTBLUR, true);
> SC_RecorderCam->GetDataInstance()->SetBool(CAMERAOBJECT_REARBLUR, true);
> CreateKey(doc, SC_RecorderCam, currentTime, CAMERAOBJECT_TARGETDISTANCE, SC_FocusDistance + SC_FocusOffset + SC_DeFocusOffset);
> CreateKey(doc, SC_RecorderCam, currentTime, CAMERAOBJECT_FRONTSTART, SC_FocusRangeMin / 2);
> CreateKey(doc, SC_RecorderCam, currentTime, CAMERAOBJECT_FRONTEND, SC_FocusRangeMin / 2);

The functions CreateKey and CreateVectorKey look like this:

Greetings and thanks for any help,
Jack
Or is there anything bad about it?
