Hi,

I’ve created a material applied to a quad on a scene 2 ( Framebuffer 2 )

That material has a Server Channel Shader with Channel set to Server Channel 1 ( Scene 1 on Framebuffer 1 )

What I expected then is Scene 2 outputing what is playing on Scene 1.

Scene 1 is indeed playing but Scene 2 remains black.

Any idea ?

For me this works as you described;

Hi Simon,

Can you send me your project, I’m sure I’m missing something.

Make sure you’re not trying to send the scene to the same framebuffer that the sever channel is trying to use as you can see above the server channel I want to use as a texture has no framebuffer assigned.
