How to make ALINE draw to UGUI and mask crop with other UI?

I’ve made many attempts to use an additional Camera TargetTexture and have never been able to get the screen image to RawImage.

using (Draw.ingame.InScreenSpace(camera))
Draw.ingame.SolidRectangle(new Rect(0,0,Screen.width/2,Screen.height/2),Color.red);

Thank you very much, I went through the documentation but missed

DrawingManager.allowRenderToRenderTextures.

I had added this sentence when I first got ALINE, but now I’ve missed it again after I started using it.
