Outstanding performance and quality!
What do you like best?
Quality and performance are two major pros of this software. Thea Render can be used in synergy with modeling app and as a standalone studio what gives more flexibility working on different modeling apps and merging all pieces together inside studio without any effort. Output of Thea most of the time is good enough to send images to client without taking extra time for post production.
What do you dislike?
Since some time development of Thea is very slow and there's not much information provided when and what will be improved. General UI needs improvements there are lots of small things to change which could improve using this software. Presto Engine should finally support procedural noises and also there could be direct connection between Substance suite and Thea material system.
What problems are you solving with the product? What benefits have you realized?
I'm using Thea Render as the main rendering engine to provide my clients highest possible quality images. Thea provides enough speed to work with clients on actual images without taking extra time to show client how final image could look like.
