I did the drag and drop thing, and it shows my texture name, and displays it in that little square... still doesn't show up in game. However now there's a fun new issue. For some reason, any new part I put into the game keeps being replaced by a model from an existing one (romfarer's subeam laser), wiping it out in the process. So the model for that keeps showing up, even though I haven't referenced it at all in the cfg, and the model in the new part folder has not changed in any way. It's almost like I'm overwriting the cfg file for the laser (which I'm not, totally different directories). Logically, the only reasons I can think of for pulling up another model, are an incorrect ref in the cfg, or using the incorrect 3d model file. Neither of those are the case, so I have no idea what's happening. Think I'll take a break, perhaps reinstall ksp and then come back to it when I've learned more about blender. Hopefully whatever issues are messing this up can be avoided next time. Thanks for the advice and suggestions everyone.
