3Delight Rendering defects

yuri1810

Hello, I'm getting some troubles when I render a scene with 3Delight: basically, if I add more than 2 or 3 ambient lights (using DistantLight), making specular one for each of them, in the final render appear different color spots, stains or even whole colored covering especially on the genesis skins. I made several attemps changing the light parameters and at first I noticed that it probably derived from the intensity of the ambient lights created, because if I lowered it under 20%, the problem disappeared. However, now I added another ambient lights in the scene (so I have 6 lights, not considering the specular ones), with 100% of intensity for the main Distant Light and 20% for each Ambient LIght, but I continue to obtain the same problem as you can see in the image below (red spots on the hairs). I'd really would like to increase the brightness of the scenes increasing the lights intensity or adding more lights, but I can't understand what this defect derives from, exactly. Thanks for your help!

Are you using raytraced shadows?

No, I'm using Deep Shadow Map. I followed this tutorial: http://docs.daz3d.com/doku.php/artzone/pub/tutorials/dazstudio/studio-lighting00

I thought so...

DSM shadows have always had that problem.  It is a deep seated flaw in the algorithm for calculating them...the fix is to use raytraced shadows.

Ok, I will try with raytraced then. Thanks!

So I have solved the previous problem using Raytraced Shadow, but now I have a new one: when rendering, the skin of genesis is totally white, like it was "burned"! When it did that, I have a series of error messages on the rendering history, like these one taken on another discussion:

3Delight message #45 (Severity 2): S2069: the interface of shader 'C:/Users/Sisca/AppData/Roaming/DAZ 3D/Studio4/shaders/brickyard/{407f8e5c-3a9b-4708-b5e5-799ff1fe7c1d}/shader_Displacement.sdl' is invalid
3Delight message #45 (Severity 2): S2051: cannot load shader 'brickyard/{407f8e5c-3a9b-4708-b5e5-799ff1fe7c1d}/shader_Displacement', will use 'null'
3Delight message #43 (Severity 1): R2001: object '' (displacement 'DAZ/Uber/displacement/omDispStandard', surface 'DAZ/Uber/surface/omUberSurface') exceeded its displacement bound by 0%
3Delight message #43 (Severity 0): R2093: object '' (displacement 'omnifreaker/displacement/omDispStandard', surface 'omnifreaker/surface/omHumanSurface') used only 26% of its displacement bound

I've read that the solution could be delete the folder "brickyard" in the temp folder, I did it and it works, but the same error presents itself again every time I try to render a new scene and often 2-3 times consectively! Please help me!

Severity 0 and Severity 1 messages are just information and have no impact on the render.   Severity 2 are 'minor' problems...except in the case of the "cannot use shader" one...that is why you get the white items in the render.

As to why you are getting it so often...how much space is there on the drive that your temp folder is on?

I have free 399 GB on my drive where the folder is located

That should be enough space...unless you are trying to render something like LOTR.

I would try reinstalling the Lights and Shaders package in the Starter Essentials.  Something is wrong with your AoA SSS shader...it should not be doing that with any sort of frequency...occasionally, yeah, maybe (I haven't had it happen in months, now).
