I haven’t started doing anything with this, but I’ll tell you clearly what I’m thinking of doing. Whether or not it’s a possibility is what I’m asking.
Straight up, is it possible to have the BGE render realtime EnvMaps while the game is playing?
I was dissecting martinsh’s ocean shader demo and noticed that the reflection was due to an environment map. Looking at hisDay/Night cycle demo, I wondered if you could use the ocean shader underneath it. For that to work, you would have to update the envmap every frame to match the change in the day/night cycle.
So is it possible to have something render the envmap to update the reflection of the water in realtime?
