Real-time Reflection on water

[Cyhzault]

Hello,

I'm an IT student and I'm currently working on a VR project. I'm trying to get a colorfull and clear water with a soft reflection effect.

I'm stuck on the last part, is there a way to make a proper real-time reflection using only nodes? If so, which are the nodes to use?


Thanks for your help, i'm quite new with shader

Hello,

Thank you for using ASE, we really appreciate it. Reflection in VR can be a bit tricky, have you looked into Real-time Reflection Probes?

Be sure to check the included Simple Refraction sample for a custom node network example.

Looking forward to your feedback.

Thanks for your quick response

I wasn't aware of Reflection Probes, this seems to be what i'm looking for. I'm going to look into it and i'll let you know if i manage to use it nicely.

I really appreciate your help (and your product),
Money well spend

Nice day,

Hello,

No problem, happy to help!

Thanks!

Hey. I was trying to do reflections using the example from the simple refraction example but I get the whole reflection moving too much. I would like to have it only close to the island in the distance and not have it slide around whenever I move the camera.

Could you provide me some assistance with the issue?

And as for the reflections using the reflection probes, I can't access them from the nodes in amplify so I don't know how i should sample the current texture that is stored in them. It works fine with premade cube maps, but the reflection doesn't work with reflections probes for me. Is there maybe something more that has to be done to get the reflection probe set up to work?

Greetings,

I'm afraid there's not much we can do to assist you, accurate reflections are not straightforward, definitely would involve some work depending on your requirements.

You cannot access probes directly but if you're using Custom Lighting you can try using the Indirect Specular Light Node.

In regards to your specific Light Probe issues, we might be able to help. Can you share your current shader?

Have you considered using Screen Space Reflections?

Thanks!

I managed to get reflections working with reflection probes in the meantime. The specular values were off in my shader.

The effect looks nice but I'm still considering if I should use it or not as it's a big hit on the performance even at lower resolutions.
