Custom CSS player causes consistency error

I rigged the HL2 Metrocop in CSS animations. Works out of the box, but it requires sv_consistency 0.
Is there any way to fix this? I have seen and used a lot of custom player models and they have always worked perfectly.
Any help would be greatly appreciated.

Thanks in advance.

Add this to the end of your .qc, BEFORE $collisionjoints “phymodel.smd” {

$bonemerge "ValveBiped.Bip01_R_Hand"
$bonemerge "ValveBiped.Bip01_L_Hand"
$bonemerge "ValveBiped.weapon_bone"
$bonemerge "ValveBiped.weapon_bone_Clip"
$bbox -13 -13 0 13 13 72

If that’s not your problem then remove the shader “Halflambert” from your model’s .vmt files.

Also how do you compile models with the HL2 Skeleton on CSS anims? I have been wondering.
