tx 1000 (start point (left corner) of the tile)
ty 1000 (start point (left upper corner) of the tile)

Now you got the left upper corner-point where the tile should start, normally left upper corner is tw 0, th 0


Next thing is to define, how big the tile is (to the right and down-wards)

tw 1000 (=tile width)
th 1000 (=tile height)



so the command for the first quarter is:
render -tx 0 -ty 0 -tw 2000 -th 2000 mySceneName.mb

2nd Q
render -tx 0 -ty 2000 -tw 2000 -th 2000 mySceneName.mb

3nd Q
render -tx 2000 -ty 0 -tw 2000 -th 2000 mySceneName.mb

4nd Q
render -tx 2000 -ty 2000 -tw 2000 -th 2000 mySceneName.mb

Is that not a way do divide my images to get a higher resol for each Q . I don,t understand how maya could render the Q's separatly
Do yu understand wht i mean??
