unable to use engineImportTXD

[Egekan]

I've a server to test customskins I've made. The script works fine with skinid:217.

Whenever I try to use the same code on id:141 or id:283, it doesn't work at all. engineApplyShaderToWorldTexture is not working aswell, I've made some sultan paintjobs by using the function before. So I know how to use it.

Script:

function staffskin(plr)
txtstaff = engineLoadTXD("csher.txd")
engineImportTXD(txtstaff,283)
txtstaff = engineLoadTXD("skin2.txd")
engineImportTXD(txtstaff,141)
end
addCommandHandler("marineskin",staffskin)
