When I ported COD4 models, when I put them into raidant, they come into radiant sideways, on it side, it never comes in correctly, how do I get custom models to stand straight up and not on its side?

Do I have to rotate the model in Blender? or does it have to do with something in assest manerger?

rotate in blender :)

you are using my BlenderCoD addon, aren't you?

I recently noticed, that model rotations aren't right. I'll try to fix this for the next release.

Yes I am, but okay thank you :D

You could start a new map and place your model close to the zero zero zero coordinates, then rotate your model in radiant and save it as a prefab

just rotate the models with the rotate buttons.

i just exported a test monkey head, looking in y-axis direction. In Radiant it's oriented correctly. Might have to do with Armature, hence different default orientations in radiant with or without Armature / Armature export option enabled

Looks like the Armature matrices use a different coordinate system. I got a root bone matrix of

X 1.000000, 0.000000, 0.000000
Y 0.000000, 0.000000, 1.000000
Z 0.000000, -1.000000, 0.000000

instead of

X 1.000000, 0.000000, 0.000000
Y 0.000000, 1.000000, 0.000000
Z 0.000000, 0.000000, 1.000000

Root bone points upwards.

Well, go to
%appdata%\Blender Foundation\Blender\2.61\scripts\addons\io_scene_cod\

Open export_xmodel.py in a text editor and change the line
b_matrix = bone.matrix_local * a_matrix

to:
b_matrix = bone.matrix_local * a_matrix * Matrix(((1,-0,0),(0,0,-1),(-0,1,0)))

It should align the root bone's matrix to radiant coordinate system, but i'm not sure if it messes up the (other) bones...

tried this (because when used playFxOnTag() the fx was played in the wrong direction) but blender gaves me this error

if you create your model+bones+parenting AND rescale the armature, the armature is twisted by 90 degrees ingame, but the model still stays as it should

Sorry, i forgot:
You need to add another line above
b_matrix = bone.matrix_local * a_matrix * Matrix(((1,-0,0),(0,0,-1),(-0,1,0)))

add this:
from mathutils import Matrix

please test the result ingame and tell me, if the bones are still wrong orientated
