I am having terrific difficulties with the path tracer. I am adjusting lighting for hours on end, but cannot get satisfactory results with any of my models. 100% of my models are indoors. The renders are coming out grubby for want of a better word, please see screen shot. Rather than crisp even at high lighting, the edges of sharp objects are 'swirly' like they have been messed with in photoshop
The example below I have dropped the exposure a bit to show the issue more clearly, but it is there all the time
Anyone any thoughts on this?
12 gen core i7 cpu
32 gigs ram

Try a larger resolution, more samples per pixel under render settings so that the denoiser that comes in to clean up the image comes in later.
Hello Irwin​ ,
Thank you for posting in the community and was wondering if you tried what , and did that help?
Kind regards,

I did indeed try, it did not make a terrific difference. For separate reasons I got a 3080 with 12 gigs of ram, this gets me to the rendered image quicker but its still the same.
IN reality I am really struggling with path tracing in my scenes. They are typically dining spaces in large buildings so the rooms are usually 16m by 16m kind of thing, not the small rooms of twinmotion example files, and the balance between natural light and lights I just cannot get to work in twin motion sadly.
I will battle on trying, on occasion I get a good result but it does not appear to be something I can replicate reguarly. The room in my image above is around 12 metres by 15 metres. It has windows on two sides running hte length of the room, the results should be bright and airy as they are in real life, but I just cannot get the balance right leading to dull, lifeless images or highs being blown out. Typically what I am getting is an ok image indoors but it looks like night time outside the windows. even though sun is high. Turning down lights inside makes the outside look brighter which I get but then you get flat images. None of the help files/youtubes help in my case because they all relate to tiny, 4 metre rooms, or outside, I have experimented with rooms at that size and its dead easy to get a good result.
I love twinmotion though, I am not moaning, its just hard to get a good result in large spaces indoors.
