im am trying to model the warthogs tires, i am using milkshape and 3ds max, the first thing i do is export the model from HMTv3 to my desktop, then i open the model with milkshape, i use milkshape to export the same file back to my desktop in a new file extension so that 3ds max can open it, then i imported it into 3ds max, i did all my changes i never added nor subtracted and vertex's or indices, then i exported that new model from 3ds max to my desktop again in a new file extention so that milkshap can import it again, then i import it into milkshape, everything looks fine, so then i export it back to my desktop in .obj format so that i can put it into HMTv3, now when i open HMTv3 and click pcmodels vehicles\warthog\warthog then i click tire (0) - 632 vertices -- 872 indices and then i click import, and i select the new .obj file on my desktop, then it says:

the number of vertices in the old and new models do not match, continuing may cause unpredictable results. continue anyway?

then i click yes, contiune anyway, then it gives me an error:

ERROR: can't inject. Indice problem
maximum amount of indices for this model is 872, your model has 1115

but i didnt add or subtrac anything, i just moved the position of things, can anyone help me to figure out y this does this, i am desperate

PLEASE HELP

Well I did use milkshake to edit the banchee and I exported it and imported it with hmtv3 and it imported just fine, but I forgot to check it out, and I already deleted the bg.map file. All I did really was edit the wings. Nothing major, so maybe just minor changes would work.

yah, i use milkshape too, but what im trying to do isnt workin in milkshape

ok wut i want to do is make the rear tires look like treads, kinda like on a snowmobile, like an elongated wheel, and i want the front tires to be like skis, like in a snowmobile, but with milkshape its not letting me select the vertexs i want and stuff like that
