how to convert transform maxtrix4x4 between 3dsmax and unity ?
here is what i want to do :
1, in 3dsmax using python get a node’s transform matrix , write it to a json file
2, in unity3d using c# read the json infomation and convert it to unity3d matrix , then set it to a gameobject
what bother me now is how to convert 3dsmax transform matrix4x4 to unity3d transform matrix4x4
i dont known how to do the math. . .
3dsmax is using z-up righthand coordinate
unity is using y-up lefthand coordinate
