Reality Lighting Trouble

Francis Taylor

Here are some examples of the same scene lit with reality & compared side by side with my custom tweaks in DAZ Studio. I find Reality & Lux Render very troublesome in my experience with it. I just can't get to the level that I see all other artist reaching with the Reality & Luxrender Plug-Ins! These are side by side comparisons of my results. I think i'll stick with lighting my scenes & characters myself. Does anyone have good advice that can help me? I really want to learn how to light my scenes in Reality & Luxrender! HELP ME!

I'm not a great lover of Lux render because it seems to take forever to cook a reasonable image but where it scores is it calculates reflected light. Where your image looks poor is you don't have anything in the scene to reflect the light back so aren't really achieving anything more than using DAZ lights.

If you create a full environment for the light to work in you should get a much more dramatic difference.

You might also have your renders reaching "good enough" quality faster because there is a surrounding scene. I don't have Reality, but I've seen this happen with Luxus; if too many light rays end up going waytheheckoutthar the render picks up more speckles, and they take longer to go away, than in a "complete" 360° scene. It seems to be one of the differences between 3Delight and LuxRender, a scene frequently works better as a complete environment, not just what's visible in front of the camera.

These are complete scenes that I have rendered with custom DAZ Studio lighting tweaks. Its really good enough for what im trying to achieve...but I could never reach this quality with Luxrender & Reality.
Thanks for the feedback.

That is actually one of the major differences between the types of renderers that Luxrender and 3Delight represent. Luxrender and its kin, NEED a full environment for best performance, 3Delight and its Renderman kin do not, but don't suffer from not having one, although if one wants 'environmental' as opposed to mapped reflections, they do need a full environment.

Hi
You have achieved a amazing result with Daz light system ! Your scenes are extremely well done, congratulations!

About your first image made with reality :
Your first image looks dark and this is just a dial in lux to make it brighter during render.

So 2 questions :

1. Do you just set up your usual Daz light and try to render with lux or do you add specific light for reality and lux?
2. Do you tweak the lights during the render to change the effect? This one brighter, this one darker, this one more cold, etc

As for environment in lux, yes i agree, it will look excellent BUT it's not an obligation. The image in my sig is a lux render, and the reflection on the eyes comes from a square light mesh in front of the character.

That is sound advice, but it's not entirely accurate.

I don't know how he does it!
