Ciao,

I’m trying to recreate a game-engine workflow where the material has the diffuse baked (used as emission) and reflections in real time (not RT realtime).
My scene doesn’t have light but I need reflections from an hdri map or whatever.
I tried via puzzle to enable screen space reflection but it doesn’t support glossy reflection, and I don’t get good result.
Is it possible?
Thanks in advance

You can put environment pat directly into material and combine it with a diffuse map how you want. Look at the example.

but I don’t know how to combine a shader with a baked map plus a reflection map.
If I add an environment map in the world setting it lights the scene.
If you have time can you look at my scene.

This is a comparison between the render and what I get in webGL. Top is render, bottom is webGl

Ssr is very slow. Better to use environment maps and reflections from the point light.

I’m sorry but I don’t understand your solution. I don’t have any light in the scene, everything is baked.

Here’s I’ve made some changes in your example. It’s a very tricky way, but it’s the only way to get what you want. Better to bake separate reflection mask for better control where environment map must be shown.

Thanks!!! It’s what I need. The sphere doesn’t reflect the floor, I think I’ve to create the environmental map based on the scene, but for a particular job I’m doing it works very well. Thanks again!

Yes, to get exactly the same reflection better to bake environment map from the scene. Good luck
