Master Lighting and Interiors
« on: April 30, 2021, 04:45:06 am »
Hello again!
I think this is probably not the first question here that relates to lighting.  ::)
But I have also tried to find as many answers as possible and have also tried them out. But I don't think I can do it without asking you. Basically, I have set up the lighting as described in this tutorial :

But somehow my window view takes away a lot of light and shadow details, although it is not visible in shadows. And my physical light outside the scene is made like decribed here - > https://youtu.be/50qIeiKqPTA?t=3324  :-\
But here are two example pictures of my scene where you can see what I mean.

And what I absolutely cannot understand is the difference between real-time rendering (see screenshots in the first post) and the rendered final result with the same samples like the screenshots!?

Is this a point that works better in KS 10.2 Beta?
Because KS fixed many things like this for example:
Fix discrepancy in direct lighting calculations between CPU/GPU
Perhaps this also includes that what I mean?

Oh man what should I say.
I found my "mistake" why I'm getting so much flakes on the last rendering.
My window glass was "Solid Glass" and I used caustics so that the light was be able to pass through that material.
So I changed the material to "Glass" and don't use caustics. And now the result is pretty much better  ;)

PS: Actually I render with Version 10.2 because I couldn't wait for your answers :P

Haha glad you figured it out Daniel! I have made the mistake to of using Solid Glass. You really only want to be using that material when you have a solid glass product that has complex scattering through it, interior should just use simple glass. Glad you put your updates on the forum for others to learn from, happy rendering!

Yes, I also thought it might help others.
Rendering individual products or entire interiors are different ways of doing it.
And the screenshots show the difference quite clearly.
It's better than just describing it with words.

I totally agree, interior rendering is definitely more challenging than product renders, regardless of what software you are using. It took me forever to get the 'outdoors' in an interior to look right and to still have enough light streaming in through the windows! Good on ya for figuring it out!
