Vue F.A.Q (Last Updated: 2024 Dec 30 8:14 pm)
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.
I wonder if it's the material that you using tranfering color to the scene. It seems to me that you got weird colors happening there. You can always go to E-on and point them to this tread in the bugs spot on E-On's site. Thing I would do first. set everything to white. Like I mean everything in the atmophere editor. Change the material. maybe use a mapped white picture texture, try it. It could be coming still from the complex procedural materials.
Hi JDWohlever, I stumbled over this, and a related issue, some time ago. My conclusion (mainly based on educated guesswork ;) ) was that Vue hits an internal render precision limit and hence introduces rounding errors -> colour hue shift -> pink/red. Only thing that could remedy it would be a higher precision render engine. But that's, as I mentioned, only guessing. I asked e-on about their internal precision settings before when running into a problem with very soft and very faint spotlights, but haven't received a reply, yet. We'll have to wait and see. ta, -Sascha.rb
