Closer look at over sampling

Pictures are rendered with animate and saved with openEXR Float (full). Then I imported the picture in Photoshop copied the right version to a 16 bit image with the doubled horizontal resolution. After that I converted the image to 16 bit because the filter "remove scratches and dust" is n...

Re: Test scences GPU Path vs CPU BiDir

For my beer glass, I modeled a few different drop shapes, then distributed them on the outer glass surface with a particle system. Thank you for this input. I already thought about to buy the new blender add on FLIPS. I will try the demo version first to look if it is faster than built in fluidics....

Re: Test scences GPU Path vs CPU BiDir

Note that with supersampling you reduce the filter radius (indirectly) when you downscale. You could try to use a smaller filter radius in the normal-resolution image, this will make the image appear sharper. Usually I render without any filter. Did you save the high-resolution image as 32 bit EXR,...

Multi Samples vs Reduced HiRes

Two Beers 1280 S CPU BiDir Sobol Depth 50 1080.jpg Well, obviously the picture from the last post shows much more details than the one above. I've assumed such a result based on several observations during fireflies fighting sessesion. The 4x resolution rendering (16x pixels) is about then percent ...

Two Beers and a Mirror

Foam is built with even more bubbles. Info notes 500 MTris, 200 kS/s, 90 Samples. Two Beers 90 S CPU BiDir Sobol Depth 50.jpg EDIT 1 Now, the same picture but rendered with 2160x2160 and reduced to 1080x1080. Spot the difference. Two Beers 90 S CPU BiDir Sobol Depth 50 2160 reduced to 1080.jpg Okay,...

Just two intermediate Beers

There are still a few things open. Water looks rather like wax. The water simulation is time consuming beeing improved. The foam of the beer in the back is too bright. The black background leads to strange looking water drops. And I have no idea why the beer looks turbid.

Reasons for Snow: Ev. Light or Sun

Gain does not have any influence on environmental light's brightness. Env. light has the ability to pass throu material matte and throu every little split in a model adding snow or fireflies. I tried to have scene with env. light shining throu the window but no matter which gain I set, lamps inside ...

Foam simulation is complex

Well, that is a good idea, B.Y.O.B. Nice scence and your beer looks close to be drinkable. At the moment I'm far away from a good scence. Table and chairs are old models. Some of the my first models actually. Again, I'm fighting with fireflies using Sobol. Roughness seems to be one reason for them. ...

Re: Foam simulation is complex

First I prerendered a minute or two to get the clamping guess. Then I checkmarked clamp using the suggestion. And started the render with Sobol adaptive set to 0.95. This lead to 215 kS/s for the 121 M Tris scence without any fire flies. Hurrah! Denoising is off. The bubbles' size is a bit reduced, ...
