ProRaster has no internal limitations that will limit the number of scenes you can work with. The primary limitation is the amount of installed physical RAM. Opening scenes consumes memory, and keeping enough scene data in the tile cache to optimise performance will consume all your memory! I recommend having at least 16GB of RAM. But, if you are serious, make sure you have 64GB or more. Even so, it ought to be possible to create products that reference hundreds of, or perhaps a thousand, scenes. 

Another practical limitation is storage space. Each scene will consume about 1.5GB of storage, and it is a good idea to have your scenes on an SSD. If you are running ProRaster on a laptop with only a 256GB main SSD, you will quickly run out of high-performance storage space. 

Performance considerations will also limit the number of scenes that you can work with effectively. This can be partially mitigated by higher performing processors with a larger core/thread count, but even the best computer will reach a practical limit. It is my intention to improve the efficiency of the software in future updates.
