I wonder if object orientation axis information should be given in COLLADA files.
Let’s give some explanation :
- in 3DSMax, a camera (for exemple) looks in the -Z direction
- in my engine, a camera looks in the Z direction
Thus, my importer have to known which DCC exports the file to change the direction of the cameras (and lights) according to the DCCs “direction axis”.
Some information in COLLADA could say which is the Direction and Up axis for the cameras and lights ?
Does someone have the same issue, and know how to handle it properly ?
