"If you are that desperate to ditch Firefly, then why not use Vue? It's a proven way and it sure beats any game engine or GPU rendering engine out there. Once you master Vue's rendering engine, you'll be amazed what it can deliver, it's a whole different thing. But also that one needs time to be learned, but there are a lot less obstacles to overcome when using Vue in combination with Poser. They work very well together, since both companies have put time and effort into making them work together."

The Above would be My advice as well.
And with vue you will get the benefit of being able to create Excellent outdoor renders without having to fake it with cumbersome "envirodome/Skydome" props and such as many Firely users still have to deploy it seems.
