Do you have UV for every parts? Looks like it.
... exept the grenade-launcher (but will be on separate UV, like optical devices). Doe, came down to the thing i had feared. Wanted orifinally to have all the weapons as a single-model to preserve some space due to usage of some of the same parts. Yet, i had a longer discussion with a guy doing some mods elswhere and seems i will have to abandon this idea all together -- meaning, i have to re-do the hierarchy and UVs after all. That will be taking a little time ... doe, in the end, each weapon will have a separate UV, getting better resolution and engravements/labelling will be better to do, but i have a little problem elswhere ...
Still all the weapon parts will be in the blender file together (only exported and OT-imported separately), but i do the hierarchy for each separate weapon, duplicating the stuff, that is used several times and give all the stuff for each weapon to its own separate UV. Yet the problem comes with aditional equipement. My guns now are in basic versions, but all butt-stocks and grips will be widened trough RIS-versions and aditional equipement on those and the same for some of the reciever-cowers (doe reciever cowers arent a problem cause i add just a RIS mesh atop it) ... meaning, there will be sometimes 3 or 5 versions of the grips/stocks and i have two ways now :
1.) Ill do a separate UV for each weapon just for stocks and another for the additional equipement (the bad thing is, i had to leave empty spaces in each weapon UV for aditional stocks, witch will only come, and i would gradually add them into these UVs ... its kinda what i have done till yet, but probably isnt much good for possible changes due to space, or for work that you want and need to do with it)
OR
2.) Ill start do certain parts with separate UVs, witch texture-size will be smaller acordingly to the resolution of the gun (if three frontgrips - ech will have its own smaller UV) and the same for each additional equipement (RIS-mounted hand-guards of various types, flash-lights, lasers etc - kinda like the optical devices, but these would have the textures smaller too, acording to the size of each element). It would be kinda better as aditional stuff can be called in and placed trough script and other modders could add theyr own pieces to it this way easyer, having theyr own UVs ...
It shouldnt take too much time - top 2 days to re-shuffle the stuff both in blender meshes and the UVs.
I thought to go the second way. But im not sure it it is good to have so much texture files in a game ... doe, can be just my stupid feeling (well at least my vehicles have a ton of them ... but they arent small objects like small-arms are). What ya say M7 ? Should i really do it the second way ?
