Bug or missunderstanding (Viewport render to texture)?
I'm trying out custom post processing and rendering to textures.
Not sure if I stumbled over a bug in 3.1 Beta or just don't grasp the concept yet.
I have the following scene:
Inside the first viewport is just a camera and 2 identical meshes with an alpha faded texture.
Mesh1 is on culling layer 1
Mesh2 on culling layer 2
The main Camera sees only culling layer 1
then I have another Viewports without shader and a transparent background
It has another camera that only sees culling layer 2
My goal was to only process one of the 2 meshes with a post processing shader
Since the ViewportContainer for camera2 has no shader yet, I would expect to see 2 identical meshes.
But it seems the viewport messes up the alpha blending somehow as the mesh on culling layer 2 darkens the background.
Do I just missunderstand the concept or is this a bug?
