Meteors Incoming!
Import Blender to Unity3d Next was to import it into Unity3D, I also only just found out that Unity supports blender files! http://docs.unity3d.com/Documentation/Manual/HOWTO-ImportObjectBlender.html
Export Blender file with Textures Next up is to find out how to export the blender file with the textures. I couldn't really figure this out and read something about uv unwrapping which I did not fully understand. Its clear that Unity does not import the materials directly, so I fumbled around a bit but managed to magically get it working after a while. I'll come back to this after the jam.
Meteor Particles I also worked on the particles systems for the meteor. I made them change color over their lifetime but I almost forgot how fire looked like for a moment and totally messed up the gradient! I set it like red->white->yellow->black for some strange reason. Luckily Google comes to the rescue once again.
Next was to make the particles always move up in world space. I found the solution here: http://answers.unity3d.com/questions/281475/how-do-you-make-a-particle-effect-always-emit-upwa.html
After that, I also realized I had to split the particles from the meteor, because I wanted to randomize the rotation of the meteor mesh, while still have the particles emit upwards, I could not find a way to do that with the particles system, so I made an empty gameobject with just the particles and sphere collider, and set the meteor mesh as a child of the new object. This meant I could rotate the mesh without affect the particles.
