Thanks! Yup, it is still very a WIP, so I appreciate the feedback! This of course means I will need to UV twice then for each gun? Although I guess if I do the entire gun first, then delete the shield that will work as well without having to re-UV everything.

Expect some more updates by the end of the week, hopefully I have more free-time to keep at it!

Lastly, by 1024^2, do you mean 1024 by 1024 then? Just making sure ^^

1024^2 = 1024x1024 indeed

.

Looks good!

Yeah, you don't have to UV the guns twice. UV the one with the shield and that's it. The gun without the shield can use the same UV, it just doesn't use the shield texture.

Quick question, when wanting to optimize the UV space, for instance on my ammo box, I am wanting to stack certain faces on top of each other that will use the same texture. Do I just want to put them over each other in the UV map, or do I need to weld/stitch them together? Thanks!

Let me know if I didn't make any sense btw XD

just overlap them ontop of each other, they dont dont have to be welded or stitched. This method saves a lot of spaces for identical uv shells(pieces) it does however some downsides

- When you bake out a ambient occlusion map, you have to move all the overlapping shells.
- When you go to texture camouflage over it for example, all those same pieces will have the same texture so you have to do a bit of work to make it all look seamless.

These are minor considerations though and we can cross that bridge when you get to it. Just letting you know they exist.

Sounds good! Practicing a little photoshop on my arty shell to try and make it look better...doesn't help I suck with how to make certain colors like brass, lol, this is as close as I could get before ragequitting :P

Ok, for more practice I have UV'd my ammo box (box, lid, 3 rounds). As said before by someone, red mean overlapping, correct? To save room, I overlapped faces that will have the same kind of texture to them (example: the entire lid is wood, most of ht box is the same kind of wood, the shells are all brass, etc).

Is this the correct way to go about this, or should I be setting them all out individually to avoid the red? It does not come out red if I do not overlap them btw, if that makes any difference.

As tim said above, if you have overlapping faces, you need to move them out of the UV box before you bake anything. Just leave one of each there.

Gotcha, thanks!

Ok, as a quick update, I've been learning more UVing and began unwrapping piece by piece, combining them at the end. Here is what I've done so far, not organized or anything yet obviously. Lemme know if u have feedback! And the only thing I've had any issue with is on the base cylinder on which the turret will pivot (Picture 2)
