Adding emissive textures causes invalid part error in KSP?

[SkyWest1218]

I'm working on adding thermal animation to my model, but when I load it into KSP, the game says the model is either invalid or missing. I removed the thermal animation in Unity and it worked fine, so that's definitely what's causing the problem. I read that someone else was able to solve this issue by using an older version of Unity, so I downgraded to the same version they said they switched to (version 4.2), yet strangely, the problem persists.

My only thought is, is this an issue with Part Tools .23? Otherwise I'm totally confused why this doesn't work, even when I followed the guide posted on here to the letter...

I occasionally get the same problem, but the only way I've found to solve it was to redo the entire animation unfortunately.

Is this part using any tags? Because if you use an incorrect tag (IE: no_attach vs noattach (ignore caps here)) the models refuse to load in game.

I had this exact same problem yesterday and what I had to do was select the object in the assets folder of unity, and at the side in the inspector window click animation, then untick import animation, now do your thermal animation in unity as normal and it will hopefully work (if yours is the same problem as mine) seems with me it was blender deciding my object had an animation when it didnt and the blender and unity animations conflicting. hope this helps!
