I’m in the process of creating an underwater survival horror game. The buildings and textures are no problem. I have no problem with underwater scenery (which is really basic). I’m just wondering how would I go about creating an underwater effect when you look out windows. I only have the free version of unity 3d. Any suggestions would be really helpful.
If you are not able to use the Unity Pro image effects, I would suggest combining a suitable fog that limits view distance with particle effects that mimic bubbles. The key to all of it will be how you use lighting and colors – but those are aesthetic choices.
I’m pretty sure you already solved your problem but if anyone has the same problem, there’s a simple solution that does not require Unity Pro.
There’s an script you can attach to your camera here.
Also you can add underwater reflections just by using a projector with a water reflection texture and it looks amazing.
