Ocean Material / Underwater God Rays

Hey Everyone!!!

I have SCOURED the interweb looking for assistance but to no avail, SO I thought I would ask you awesome people!!

Have any of you played Subnautica? Well I am basically trying to do the underwater godray effect that is in that game, aswell as possibly getting a material together that is similar to the ocean material in that game as I REALLY like it :) I have a basic water material i put together, aswell as some caustics in the form of a decal, but ya, just wondering if someone could be so kind as to point me in the right direction for information on this, or assist me themselves :)


HAPPY 2018! :)

in the Ocean Floor market place pack (which is really good), I think he uses static meshes as light rays... you can also add light rays in lighting setting I think

Aye, I have seen really good ocean materials on the marketplace but can't really afford to buy anything right now :( I Have tried adding a directional light and enabling light shafts but they wont go through the water material i have made :( Ideally I would love to have the light shafts flicker and be affected by the waves in the water themselves :) thanks for the response tho buddy, really appreciate it! :)

sorry I couldn't be more useful!

I do understand... the water material may complicate things. By the way, here is the marketplace Ocean Floor environment. It's really good, but it doesn't have a water surface https://www.unrealengine.com/marketplace/ocean-floor-environment

dont worry mate I appreciate your input! :) ahhh ya I saw that a little while ago, it does indeed seem like he is using a cone mesh for godrays, I am trying to get it to look more like the godrays are affecting the whole ocean and not just certain areas. and I can NOT seem to get a good looking ocean material made urg :( subnautica is ideally what im trying to get..ah well back to the drawing board :) thank you so much for your help buddy! you sir, have earned a cookie :)

i would start with Water Surface Overview | Live Training and check out the water planes project on the learn tab of the launcher. Im not 100% on if you could use the materials from those in a game you sell but it will help you to learn to make your own material. as for the god rays its not something im totally familiar with but i would think you could accomplish it by having your ocean material translucent or masked. that way the light could still pass through and from there it would be like creating any other god ray.
