OK Jura... not the scene you wanted, I'm sure, but you reminded me of something I wanted to test. Almost 2 years ago now I started a thread on rendering single faced architecture models in Firefly using IDL (https://www.renderosity.com/mod/forumpro/?thread_id=2878037). Basically because of the massive light bleed through the joins between faces. I wanted to see how Superfly dealt with the same geometry. So here it is:

This is at 25 samples and is still a bit grainy, so render times aren't worth posting yet (still long). What I wanted to check for is light bleed. It appears there is still some, but nowhere near as much as through Firefly. This model is 'out of the box' with original textures, just rendered with Superfly. There is no additional geometry to blank off corners. I should also point out that I turned on caustics. I should also point out that there is no balcony on the model, and no ground plane in the scene. The blue light on the ceiling and the nearside right wall is from the skydome, the yellowish light around the right window is backscatter from the wall and floor. Also, there are NO internal lights here... it is fully lit from the skydome and a single infinite light set to be the sun. Also, the light is at 12,800% and the skydome at 128, which by my previous explorations of Firefly equates to a roughly 2 second exposure with 100ASA film. This is a full stop above what Firefly would cope with, so I am VERY pleased. Considering the original model was made for Poser 5, I have to give a big thumbs up to those who did the node transfers from Firefly to Superfly!

Hi there

Thanks for posting this,really appreciated there

Those single faced geometry always has been pain to render in Poser,I've same model I think is Downtown Apartment,but yours render looks OK,did you used Area lights or not,this will or can help you with better lighting

Regarding the render times,this has been rendered with CPU or GPU and regarding shader,did you modified shader ?

Agree about the light bleed,this has been pain with this model and many others where I needed to use something which would block the geometry etc,this has happen to me with several models which are single faced

But still thanks for posting the render and for posting the insight how and what has been improved on this front.

Regarding the times and render,have look I've done render in IRAY,interior scene and render time after 1 hour and 45 mins has been so grainy(with blurring I would say has been "usable") and there I've used single figure etc and this has been rendered with EVGA Titan X which I overclocked which didn't helped at all with faster times,then I exported same model or scene to 3DS MAX and there I've tested this on render engine which our company developing,there Titan X has been slow(spoke to developers and they said,they didn't updated CUDA and OCL for GTX9xx/Titan X),switched to my trusty old R9 290 and same render took me 40mins,with V-RAY same render took me 46 mins with very average settings,hard to say,due this I always will be bit careful with PBR and expecting fast render times,everything depends on settings and HW used

Thanks again for posting this and really appreciated for yours insight

Thanks,Jura
