Newbie question - reflections

What nodes are used in real-time reflections for water and mirror shaders, would somebody possibly be so kind as to show me how? Thanks in advance.

Thank you for using ASE!

There's no specific go-to set of nodes as it really depends on what type of effect you intend to create. Have you had the chance to test Real-time Reflection Probes?

Be sure to check the included Simple Refraction sample for a custom node network example, GrabScreen is usually involved.

Let us know if you have any followup questions, we would be happy to help.

Thanks!

Yes, I've looked at the simpleRefraction material. To the extent that I'm aware I don't think cubemaps give accurate enough reflections. Is there a way to accurately and literally mirror everything on a limited area on a mesh instead of projecting a cubemap? The only solution I found was the way Unity did it by using a camera and a C# script. Anyways I really appreaciate that you guys take your time to listen.

If you wan't to create an actual flat mirror effect with ASE you will have to apply your own calculations, the Screen Grab and Screen Position node is usually a good place to start. From your description, given that you also want to use it for water, it seems that you are looking for something like Screen Space Reflections.

For flat mirrors, why not use a Free dedicated solution?

Looking forward to your reply.

Thanks!

Thanks, you've definitely put me on the right track. I'll have to do some thinking on how to make the Screen Grab and Screen Position node reflect properly. And also thanks for suggesting that free mirror asset it'll definitely come in handy.
