Ok, I think I have finally figured this out. The way soft shadows works in Vue 4 is that the far fading edges of the light darken through the color spectrum. Picture a bowl. The very middle inside of the bowl is pure white. As you go further out toward the edge the white slowly goes through the color spectrum to pure black. The closest colors to pure black in the light spectrum is red, infra red so that last visable colors you see near balcness is red. When u add more lights the red, which isnt visable with justa few lights,as it is so lite, is defined with more lights, hence you get the noticable pink with radial lights. Becuase radial lights radiant in all directions for the center, thereis a cirular red area around each light beforeit fades out. With the ability to edit the fall-off of radial lights there is nothing that can be done. This is why with spotlights the pink is easier to manage becuase you can control the fall off of the spot lights so the "red" area is only at the very edges of the spotlight. SO the only way to "fix" this would to be able to 100 completely control the fall-off decay of lights which I can;t see doing.The only other option I think of is to try very dark colored direction lights as they shouldn't have any fall-off.
