How to make a animation invisible?

I need to make a FBX invisble and keep considering all variables inside this animation.

But when i set render to animation i got a error, because the animation hasnt meshrenderer.

So i have to turn their children invisble? (How can i do that?)

Or have another simple solution?

I had a similar problem, where I wanted the animation to act as a ‘skeleton’ for another set of renderers, and not to be rendered itself. The way I ended up solving it was to put a ‘cutoff transparent’ material on it, and setting it up so that the renderer was invisible. Hardly an ideal solution, I know, but it did the trick.

Other, better solutions are welcome here- if someone has a better way than mine, I’d be interested in it too!
