Maya to Terragen camera export

MAYA TO TERRAGEN CAMERA EXPORT

Made with Maya 2023

This MEL script exports camera animation and render settings to perfectly match scenes between Maya and Terragen.

The script works starting from Terragen2 

To match exactly the motion curves, the script bakes the camera animation so you'll have a keyframe every frame. In addition the script changes the rotation order matrix to ZXY (without any change in the animation) because this is Terragen rotation order by default. 

The script exports a camera .tgc node file and a render.tgc node file with Maya render settings to match the exact frame and aspect ratio of the final image.

INSTRUCTIONS

1) Select the camera you want to export
