I must admit I have no experience with 3d editors and was going just to slap logo over some existing render (as soon as i found time to do it). You've got ahead of me. Thanks.
You can also do it with Gimp (not to say Photoshop). I don't know exactly how you work in general but if you prefere 2D you can anyway integrate your symbols onto 3D stuff usable ingame. To do that just follow this amateur trick using two GNU tools, Gimp2.8 and Misfit3D (as a viewer). I attached an illustration if you prefere pictures to verbs.
Ok, if it happens you missed some point with layers or distort "filter" tool in Gimp, just ask for the details - you will essentially need to use transparency for superimposing layers, distort and scale and then export to png. Ask also if you dont see where are the models, or for anything else.
I just want to add something I found about your symbols. Playing with transformation in order to make the picture below, I found that applying a polar transformation to one of your logo was giving an interesting result. I didn't try it for all of them this night but I think you would be interested in doing that and maybe use it as a base for new stuff? Ok lets see that later.
