Is this one good enough? I could put a skin on this one? If not please post a reference image so I can see what a real good sand bag should look like.
I could also put a tied up end like this one and make it bulge more in the center. Let me know before I proceed further please. Do you want them to stand up vertically or will you be stacking them?
xbox, you might want to not have singular ones if your stacking them horizontally, you might want a model of a stack of them for performance reasons, plus shadows can be baked into the skin then.
Edit: heres a quick skinless example:
this is a level i was designing a while back, but the sandbag walls were all one model a piece allowing me to not have too many ent's on screen at once and the inner lighting on the walls would look nicer.
heres a quick model Im thinking of putting in a model pack i've been working on, I might put it as a single on gamebeep as well, not sure, but it shows what im talking about:
@xbox I put the sandbox models over here to user contributions. Hopefully those will work for some situation for your game. I made some low poly versions also, as I said on my page, my suggestion is that you add some dirt to the texture or put your own texture (the one you posted earlier) just to add some variety. But they could work good just as they are also. Good luck.
