I'm sorry to say that I just don't think the “Draft” engine is up to the task of a scene like this – I tried a bunch of things, and there were some issues, but fixing them had little impact of the draft engines output... at the end of the day the draft engine still can't clear the noise within a reasonable time/SL. [image: HYEZ_ChandellierWithNoGlass_draftSL18.jpg] If this is the type of scene you need to render often I think it really is going to be needful to use the production engine – which can do it no problem (see attached example). [image: DeG5_ChandellierWithNoGlass_prodSL14.jpg] On the off chance you want to know what I tried here is a description of what I changed (and the updated file): ChandellierWithNoGlass_jmods.zip After taking a look at the file I started to make some edits – the first thing I did was remove any geometry that wasn't needed for the render. Partially because this helps me get my bearings and find flaws but also because this makes the SketchUp file more compact. I made quite a few geometry changes and you can look at those and decide for yourself... most notably the chandelier and the rug. Then I started looking at the Maxwell settings – in particular the camera settings were very unrealistic. You had it set for an EV of 1 – for interiors a EV of 5-7 is more normal. Once I set the EV to 5 to get the camera exposure more natural I adjusted the materials – I added 2 materials: “jason emitter” and “jason emitter plane”. I used the first for the “bulbs” of the chandelier and the the second was used on a plane I set behind the camera to be used as a “fill light”. Other than that I made some tweaks to the various materials looking for too bright colors or materials using textures which were too bright. I was careful to use the entity info palette and remove any conflicting materials – meaning if the group level had one material assigned but the subgroup level had another (the table set was an example of this). I changed the wall and ceiling into my “painted wall” material, which you can download here: http://www.maxwellrender.com/forum/viewtopic.php?p=349725#p349725 Sorry I can't give you better news. Best, Jason.

Hi Jason. Thank you very much. I've applied clay material and got last scene rendered in an hour with SL=16 and Res:790*427! I read the discussion about AMD/Intel performance differences when it comes to R2. I guess there is no way to discover which material causes an issue(as long as i don't have a full version of maxwell) so i should just hide all the objects and them open them one by one to see what causes the increase in rendering time. Or alternatively I can just become a clay-addict) Thanks a lot for your help!
