Draw texture render target or on a camera view


I would like to “draw” a texture render target or a material on a camera view. The camera in question is a NDI viewport capture that is suppose to be broadcasted to another computer over the network. I want to broadcast the result of a material instead of a capture of the world. I would normaly just use a post process but that crashes the editor so I am trying to find a workaround.

Does anybody knows if that’s doable and if it is, point me in the right direction?

Thanks in advance for your help,
