[C++] How to manage two isolated scenes ?

Hi everyone,

I want to create an isolate scene with a render target camera to fill a texture and use them into my main world.

I see many people who do that using actor inside the same level but my main issue is the lighting. We can’t use directional lighting or another skysphere.

Moreover, I found the class FPreviewScene which manage this UWorld. It’s look like the system use into unreal editor to show main level + material editor.

So Question 1: Can we make this ? And how in details (create Actor ? / added it into GameMode ?)

Question2: if we can isolate scene : Can we make this workflow ?
Here, the objective is to split LevelSequencer to avoid complex sequencer. But the final sequencer must have all objects into same level ?

Thanks !

PS: May be, this ticket is confusion about UWorld/ULevel because I don’t found a good documentation about this topic and about interaction between each item.
If you have a good, I take too !

No one ?
I think it’s strange that simple case can’t be easily.
I just need for my question 1) to make two isolate rendering. In classic OpenGL / Vulkan, it just make a rendering inside FBO and mix them. The most “difficult” is just call render 0 / render 1 (sync about scene object if moving, …).
But for the moment, I don’t care about performance.
