Create a color node like ab color, assign the color and attach it to Output node/Viewport

I get that the RS camera tag is getting phased out and provided with its own RS Camera object but AE is crashing when I import my scene to retrieve cam data. I don't get access to regular C4D camera unless I change the render engine in the render settings. Any way I can make it so that I can have the regular C4D camera button/icon present when in RS is active? I put the icon in my UI and its greyed out and when I am done editing the palette it dispersal because I am in RS mode not standard or physical.
