Ok the game engine has y and Z swapped around as per normal.
this is the code im running on a selected camera to get a projection matrix. It doesnt seem to be working.
If anyone has any experience with this could they give me some help?
-- Get Projection Matrix
clearListener()

units.MetricType = #centimeters
mapped fn fnMatrixMaxToEngine valMatrix = --takes a matrix output a string
