I took a long look a that today but stopped short of installing their demo.
(nice image BTW) The deal breaker was no real time link from GH.
I really want to be able to adjust the model in GH and not go through endless delet and rebake cycles!
As far as I can tell, the Unreal engine is free but these guys want $600 for the connection to it. What are they smoking.
I am surprised none of the genei that make GH plugins have not already written that connection code. That be a giant leap for GH. Unreal has all the walk through capability with VR built in.
I thought Enscape was fantastic and fast, but again, no link.
Vray has the GH components kinda, but it is so convoluted its seriously annoying me. Its got 95% of what you need to do a scene bu that last 5% is just impossible without basically building everything in Rhino as far as I can tell. This is a mature app with some well intentioned people, but it just falls flat on its face without a college course to get to grips with basic concepts tha tshould be in the Quick start.
The other thing I dont like is that I am married to some .hdr file dug up of the internet which are a compromise at best. It badly needs a sky engine.
Then there is the issue of background elements like a coastline or an island or cliffs or rocks and so on, and then there is water transparency. I cant find any thing on these issues. I really have to read a decade of their forum posts to get to this.
