1. You can get current sky values at a position through Code or Blueprints

2. You can have weather such as rain to be regional, and that region can move with the wind. Currently, you can only change the weather for the entire sky. You can’t have it cloudy in one area and not in another ( is however a that has been worked on).

3. Like all our documentation, it is lacking but is being currently rewritten. You can take a look at the blog (https://simul.co/real-time-rendering-news/) I write, but I know will not be as helpful as you would like.

4. We do not use a material for the water, the colours are calculated through our variables. If you describe what you would like to do with the water I can give you a better answer.

The problem of dx12 is really disappointing. When we released 4.22, we expected to have a complete and available that can be used normally under dx12. It can be used in 4.22 and above versions together with ray tracing and many others. However, there is still no version that can run stably under dx12. There are a lot of update logs about dx12 in the middle, but none of them seem to play a real role.
