How do I skin an object whos material is explicit ?

Will I have to open the model in blender and create a new model based on a mapped texture

(ive been reskining ingame objects like sodacans plastic bins etc and hit a snag on the burger box close
Ive modded the texture under objects and did it just like I would anyother skin that worked but when I go to check why Im getting the message
couldnt load image models/mapobject/filler/burgerboxclose
I click on the material under the declaration editor and get the error
implicit file , line 0

thanks for any help

With a little more digging I assume I would use the renderbump command in some manner but a simple renderbump models/mapobjects/filler/burgrerboxclose.lwo (going from memory so Im probably wrong on path)
but any how I just get a flat blue bumpmap and preaty much a flat gray diffuse

If this is the key can anyone help me with the command syntax
for setting up the new mtr and skin and the renderbumpcommand

while your add it could you change my diaper Yikes I feel like Im asking someone to do all the work But Im really lost on this one
thanks for anyhelp
