seems like quality is not resolution dependent.. im just doing some work for one of my clients.. its about showers and bathrooms so that means lots of dielectric surfaces..

lets have a look at this image..



i let the smaller one render for ´bout 20h too, but maxwell chrashed and i havent saved the reder.. but i remember the quality didn´t change much adding another 15h to the render displayed here..

so.. whats happening there?.. i rendered at ultra-highres with the hd-switch and got a far more sharp and convincing render than at normal res.. and then again the sampling level thats driving me nuts.. seems like SLs don´t mean a certain amount of visual quality even when rendering the same scene with all settings and the camera being the same..



another question: whats happening to the ceiling and what about the white dots (no caustics enabled) on the right rendering? seems strange to me somehow..
tips appreciated.

thanks in advance for your comments,
eldo



ah and btw. chromatic abberation works fine for me..

interesting......so really 15h didn't add much to the smaller image? In this case it seems using the hd option and rendering at very high rez, then rescaling is a much more efficient way of rendering.

Which white dots do you mean? The render looks fine to me.
