I am glad nevrax got this out. but i am still having problems. the same
problems as before.
before i had setup my interface file the same way. their is some small
problem that i cant seem to pinpoint.. is there a checklist that you guy can
put out? so far i have troubleshooted the scene and have noticed. when i
export a model a log.log file is not made. when i exported your scene a
log.log file so for some reason the meshes are not getting welded or the
interface.max file isnt being accessed.
Does this have to do with version of MAX? i am running 5.1. i have noticed
their are bugs with the tools in 5.1. is it possible that this tool isn't
doing the job correctly? Maybe that i am using edit poly and not edit mesh?
well i have tried converting to edit mesh. nothing.
The interface mesh scene given has "lines" in place of the seams then
converted to edit mesh. is this correct? i have noticed the the differnt
interface mesh parts have different modifiers on them. its hard to
understand how to recreate them since their are inconsistencies.
i have exported hundreds of times trying to figure this out.
this is what is happening...
something is going on. its obvious that my seams are being moved. at least
its doing something to the right verts. the stretching is happening on my
seams. but thats obvious the wrong thing is happening.
so i figure if i can get a checklist of some sorts. i can finally figure
this out. get it running
