When I do eaves or the underside of a balcony the surface is black or very dark at least. How can I fix this.
Thanks

Hi Support, I am using grain free. Could you please explain "path depth" By the way the program has come a long way lately. Well Done!
Cheers

Thanks :)

You can find the setting in the Rendering options "Trace Path".

What kind of illumination are you using? sun/sky? environment map?

Hi, I have attached an image with 10 passes only. it also shows the settings. I have copied the cieling lights and put them near the floor to light the cieling a bit. Will olso choose another HDRI with a brighter sky. Any further suggestions would be helpful.
Thanks

did you set the sun position to match the sun position in the env map?

10 samples is way too low, not enough data, you'll need a couple of hundreds for it to be correctly rendered.

I have worked more on the render, please feel free to suggest improvements, I know you will suggest 3d trees but I have never been able to find convincing ones
Also do you know how to import a texture into sketchup with normal maps. I have imported texture but when I try to import into SU I can only imoprt the texture not the normal map. I am sur I could get better with good textures
Cheers

Oh, just to get back on topic, I have attached an image where I have not been able to get the ceiling to present as white. Could you advise please? Is "path Depth" the issue as you mentioned before?

:o :o :shock: :shock: WOW, these are beautiful renders!!! congratulation!!!

The normal map have to be loaded in Raylectron. First, you load the texture in Sketchup, then when you export to Raylectron, open the Material Editor and bring that texture, then load the normal map.

For the ceiling in the room, it looks correct to because you have ceiling lights and the light they produce bounces off the floor and other object, significantly reducing the intensity. I have pot lights in my living room and the ceiling is very dark, just like in your render.

If you have the Path Depth set to 12, then it's all good.

wow, this one is even better. How many samples did you let it render for?

I think about 180 at a trace depth of 12, how many do you usually render for in a scene like this?

I think 180 is the minimum for this, I would maybe go 300. From time to time, I take a sample at 200 and then I let it run all night when I go to be and next morning I compare the 200 with the 2,000 and see what's the difference, it gives me a good idea and to me 300-500 is usually enough.

Hi I have rendered this iteration with 500 passes, it came out well I think. Constructive criticism welcome.

Well, all I can say is, you're better at it than the Raylectron team :) No criticism to say here, very well done.

I thought I would post my final render. To see how it has progressed from what it was.The main thing is the fire was just an image and did not look right. I made some small "coals" with about 8 faces and made must faces black but made a few faces Burnt orange and khaki and made the colored faces into light emitters and I think it works :D
