Bugs in Animator

So, I'm at my wit's end. I have scoured the internet for months now. Not being able to find an animator that will animate my company's complex machines. The built-in Solidworks animator is full of bugs. Mates can't solve, textures randomly disappearing, etc..

This has been an incredibly frustrating experience. Trying to animate a machine with thousands of parts is becoming impossible.  

I've been trying to find a good animator that can import solidworks models. I used to use Strata, but it is a 32bit app so maxes out at 4GB of RAM. Useless with these models.

So, any suggestions would be appreciated.

MODO looks promising, but I can't find any finished animations to really compare it with. Most are characters, or simple design renders.

I need to showcase a machines movements clearing certain ceiling heights, maintaining certain heights, etc..

Thanks in advance.
