Game engines that are free. Cryengine 3.5 Unity3D UE4 is only $20 for a one-time, unpdatable buy, but comes with everything. Source code, etc. And a solid basic renderer.
Yup, you have an editor to set all that up. Only thing is for stuff with alpha you need to separate the individual objects in your project to prevent alpha sorting issues. I'd also recommend blender game engine provided your model doesn't use alpha channels at all. You have a lot of great stuff like ramp shaders and nodes…
