What are some of the biggest pains you've experienced with managing your 3D assets?

As someone who's new to the 3D asset management space, I would really love to learn from you, the developers, to know what issues you currently are facing when it comes to managing, editing, updating, streaming, etc. your 3D assets. What tool or tools do you use to accomplish your tasks? What's the biggest drawbacks to picking a platform (i.e. lack of features, pricing, not user-friendly, etc.)?
