Rendering Issue - Topmost

Closed this issue · 4 comments

Any suggestions for how to set the rendering/sorting layer? See these one is from the editor and one from injected at runtime.

It seem's UI object's will over-draw the DearImGui window. I've played with the Shader's renderqueue but no change. Any suggestions on how to make it top-most? (It happen's with just Dear ImGui also, same result, but where the hell to set the topmost? I've tried canvas sorting order, Camera depth, renderqueue, layer's, nothing change's it.)

BTW: I also made a fix for URP/HDRP Shader's not included in build's. It allows including into AssetBundles also. Like all those hidden/internal builtin shader's in URP/HDRP.

Hello!

You could use different cameras to reach what you're looking for.

You'll need to set your canvas to render into a specific camera:

It's quick test and it works for this set up
Main Camera -> Render UImGui
Main Camera (1) -> Render Canvas UI
Main Camera (2) -> Everything else

Main Camera (2)

It would be awesome if you could make a merge request with your fix or any other way better to share.

Thanks for using ;)

Thanks for info, that helps alot!

I started with DearImGui but moved to UImGui due to the added features you have, not to mention your more active on your repo. their's appears dead.

I'll get a PR setup with my changes. Good stuff, I really didn't have to modify the core UIMGui code, Just some changes mainly in uimgui.cs, in order to support bundling it into a an AssetBundle for runtime loading. I was getting issue with missing asset dependencies with URP assets and the Unity Editor wouldn't let you add them After adding a ShaderVariantCollection and prewarming the shader's, the asset's get included. I mainly had to figure out this camera thing.

Thanks for sharing, any idea how to replicate this behaviour with URP/HDRP?

For now I'm just toggling off my UI whenever I display my uimgui debug interface. Thanks for the great package by the way.

You can do using the same logic as above (I made a quick sample on URP)

Make 2 more camera using overlay and use the stack feature as described here https://www.youtube.com/watch?v=OmCjPctKkjw

UI Camera

Hope it helps, otherwise open an issue because other people could get help from there. =)

Thanks for using <3
