To update on this, here are a few test renders I’ve made with RoRender V4 so far.
This is a part of the rendered map without any filters, not very different than RoRender V3:
The particularly interesting part, with a bit of tagging and some color filters, you can easily turn it into something like these:
GTA V (monochromatic):
Google Maps:
The ease of applying these filters, especially with map changes, saves us a lot of time and allows us to let the player choose their favorite style. Definitely a fan of this!
