Render Glitches

Post by res08a7k » Sat Nov 09, 2019 6:07 pm

I have a fairly new windows alien computer with plenty of power, sketchup 2017 and the latest version of Twilight render.

Seemingly, when rendering with a lot of lighting, it gets to the end of the render, with my setting on low the render finishes with a bunch of black dots in the picture.
When rendering on prelim it doesnt have enough detail
when rendering on Low+ it takes way to long.
When rendering on interior stop when ready - takes way to long and looks a little grainy.
Please advise (see pic)Image

It could be that you have set the power for the lights near the mirror way too powerful, and they are causing light calculation errors. Lower the power of the lights and increase the exposure for the rendering in the Render Dialog bottom right corner "Post Pro" tab. increase exposure to 1.5, for instance, as a starting point, then experiment.

Or this is perhaps coming from the multiple CPUs trying to finish the same pixels all at once. Try increasing your rendering resolution (double it) and/or try limiting the number of threads in the Render Dialog settings.

If you are using light emitting surfaces, it can increase rendering times with Low+.
Have you tried with Easy04? (in combination with proper exposure and light powers?)
I suggest for final rendering quality try using Easy 09 Interior render setting.
Easy10 is overkill, and takes 2x longer than Easy09 in my experience.
