Render only indirect lighting

Hi all. Does anyone know if it’s possible in Unreal Engine to render only the indirect lighting effects of an object? Possibly when the path tracer is enabled? Basically what I’d like to achieve is complete invisibility of a select object when looked at directly, but it still appears in mirrors, is still visible when looking though glass, and still influences the appearance of surrounding objects through indirect light bounces.

Yes, very possible! I think you are looking to create a material with this setup:

Let me know if this works for you! :slight_smile:
