how would you guys approach this, on converting these values from a Y up coordinate system to Max’s Z up coordinates. for move,rotate and scale., btw sorry for the double post
the txt file i am pulling in values look like this:
nr:0
asset: bridge3.obj
xpos: 4.77926635742
ypos: 295.343948364
zpos: -474.406799316
xrot: -178.68342590
yrot: 52.5331878662
zrot: -178.026260376
xscale: 0.409979230788
yscale: 1.86230026253
zscale: 4.30338694181

something like this:
fn convertUp_Y_Z xpos ypos zpos xpot yrot zrot xscale yscale zscale =
(
y_up_matrix = translate (rotate (scalematrix [xscale, yscale, zscale]) (eulerAngles xpot yrot zrot)) [xpos, ypos, zpos]
z_up_matrix = y_up_matrix * (matrix3 [1,0,0] [0,0,-1] [0,1,0] [0,0,0])
)

ah as i assumed, a matrix multiplication
Thanks Denis!
