Hi there, I try to search around, but nothing works, Let me explain.
I Have a Widget, that i need to put the 3D model in there,
so im using SceneRenderComponent2D, If i use the “SceneColor(HDR) in RGB, Inv Opacity in A” Works i just need to Invert the Alpha , and Done. BUT
I need the Post Process Effect to work with, so i change to Final Color (LDR) in RGB, And, Now the Post Process Works! Great… Or was what i thought, now i have a Black Background, i try many ways around, but found Nothing that Works,
this is the right approach? has another way? is a setting i need to check? i dont know 
Just to see what im talking about
This is with Final Color
this is with “SceneColor(HDR) in RGB, Inv Opacity in A”
the SceneRenderComponent2D Settings
this is the Mat that i Use too call in the Widget
This is the RenderTarget
this is not the solution, i try to put some Post Process Effect to test it, and it not work, you are using the SceneColor(HDR) in RGB, Inv Opacity in A , and it not work with post process, i need the Final Color, but with final color it render the backgrounds… and i dont want it
