Question Can a front facing reflection be seen behind the mesh (Material reflection question)

I've been experimenting with reflection for the interior of a curved visor for a VR astronaut experience. I want the reflection on the outside, convex surface to be visible on the inside of the visor model, since that's what we see in real life. In unity, the convex reflection appears in the correct orientation, but the concave reflection is inverted. It makes sense as the bottom of the concave surface would be reflecting things above the concave mesh.

Is there a way to allow the convex reflection to be seen from the back of a mesh?

 

You can write a custom shader that does that but it's not physically correct. Keep in mind that reflections are view dependent, so you'd have to pick a point on the outside as virtual view point.

But I'd probably use a screen-space distortion/refraction instead:

Or just do it like Lone Echo and render just a HUD.

 

Thanks for the recommendations Code Monkey!

I ended up using a Render Texture approach with a curved mesh and the results are what I was shooting for. I'll do some tweaking over the next few weeks as I finalize the VFX, but I'm pleased that today's efforts were productive. Here's the results which show a more accurate reflection projection than the Reflection Probe approach.

 

That's pretty cool. Nice job!
