Opened a new topic for better visiblity in the forum. And screw 3D textures… for now. They are mandatory for high profile scalability and optimization but one can also micromanage 2D texture buffers and indexes and riddle them with bugs. (I should check out the cloud sample project in the Flax git. Looks like the 3D Textures used there are somehow working.)
Doesn’t look that bad. Runs buttery smooth in realtime but also misses the fancy stuff like scattering and shadow maps. From here on you can go wild and replicate all the effects Unreal Engine throws at you from the very beginning.
