Backpacks dyeable?

[roguetrooper 2]

Are backpacks dyeable? Since some infantry is and some infantry is not, I don't know if I am using the right code for backpacks or if backpacks just can't be dyed.

I've tried to dye the player's backpack black with:

unitbackpack player setObjectTexture [[color="Red"]0[/color],'#(argb,8,8,3)color(0,0,0,0)'];

unitbackpack player setObjectTexture [[color="Red"]1[/color],'#(argb,8,8,3)color(0,0,0,0)'];

No success.

I don't think so because they are configured like a weapon so you can't access their 3d model in game to change textures or animate them
