3d Rotation Daz Studio 3ds Max

RajDarge

Does anyone know the math or the method to conver Daz Quaternion rotation to 3ds Max and vice versa ?

The axis swap is doing my head in. 

12 months ago I could have worked it out, but I don't want to have to learn all 3d rotational algebra again. 

Just for reference: daz Studio axis  +Y up,  +X to the right, +Z towards the viewer
3ds Max +Z is up +X to the right, +Y is away from the viewer 

my intuition tells me to rotate the normalized quaternion in max by euler -90°

but I tried that and it was clearly wrong.

Are you trying to write a script for this?

Yes, i think i might have worked it as the rotation component of the quat should be the same, but the axis will need y and z flipped.
