I would also love some more energy weapon sprites (for my own mod). Very few of them in the loop; understandably I imagine, since stock pics of energy or futuristic weapons that would fit in with the retro-future look of Fallout are scarce. However, if you guys ever make some or become aware of anyone making some, please let us know here since I would love a few more energy weapons in my mod (proper credit given of course).
Images are one way to go, get 3D models would be a good place to check. If you have blender, or another 3D model viewer of sorts you could screenshot a model for use with photoshop. Aside form working on them yourself you could also have a think about combining your efforts with another fellow modder, it definately worked with me and Rob and can be a sure way of getting thing done right. If you cannot mod all aspects of your project, find someone who can help you out.
As for this, even though it is not a direct request to myself, I feel I should help you both out a little. Weapons are kind-of one of my advantages and maybe I should see what I can cook up for you guys. I know you are after something that will fit with the Fallout apocalyptic sci-fi style but since original Fallout weaponry has already been crafted, I don't see the point in double versions out there. Also I have been wanting to do this for my own projects for some time now. Who knows what I will come up with... Advanced tech, Energy, Experimental... Can anyone smell overkill!!!?
Give me some time and I'll post something up on my resources thread.
