Their website does say that you can pay per image at $1 per image. I am in the opposite boat though. I could see this having a very significant effect on photogrammetry but I would need to process a few thousand images at a time which would not be very feasible with their current pricing model
To the developers. A very promising piece of software for a VFX supervisor like me. BUT, please reconsider your pricing tiers and introduce a per-image price. We are a pretty large facility, but I can only imagine needing about 1-10 images a month at the very most. It's like HDRI's - we buy them all the time, one at a time. They need to be individually billed so a producer can charge them against a particular job.
Vitaly Okulov has shared a great video on speed level design Unity. The artist took his own package of assets to build an atmospheric fantasy village.
No advice on composition, but it is still a nice example of how you can assemble scenes. As you can see, the artist used a special designed tool for easier objects placement.
Did you like the village? You can build your own one with the help of package from Vitaly and his wife. A brilliant set of stylized PBR models, materials and particles in a cute fairytale style is waiting for you. The pack includes modular terrain and over 100 objects for populating the world. All models are optimized and mobile-friendly. What is more, you’ll get an Object Placement Tool — the tool demonstrated in the video.
