  • in Render to File Settings, use "Load a Preset" to load the above .pre file

  • press OK

Looks terrific...how long to render a frame?

58 minutes!

23 minutes! (I had the computer on "power saving" before )

That can probably be refined by altering some settings.

 

Here is a version that sweeps the color of the light and the index of refraction of the glass over the course of a multi-pass render to simulate the prismatic effect of the glass

 Wireframe of the vase, please? I'm curious how you ended the vee grooves at the neck.

It was just the quickest of quick vases...

I've posted a PRJ in the first post if anyone wants to play with it.

Robert asked me to render the projects with the AMD 5950x 16 cores, 32 gigs of RAM, all drives are NVMe samsung 980s with a rtx 2060

Right off the bat the two cores would not render even though I have 70 cores for netrender.

I rendered this project with a single core and each frame took about 19 minutes. 

I will update the info as the rendering goes forward.  

I shot a pic of the temp of the cpu and it was holding under 40c

Once I get finished with this I will render the project with Intel screen.jpgI9 12900f (alder lake) with 32gigs and 16 cores all drives with NVMe 980s.

So each frame is taking about 25-26.5 minutes to render.  I am not sure what Robert said it took with his computer but this has taxed this computer the most of any projects I have rendered and this is only in vga resolution.

After frame 59 all rendering stopped.  the pool appeared to be rendering but the each frame after 59 loaded and would not proceed.  I finally killed the project and will let Robert know.

Try restarting and after you load the render preset edit the frame range to start at frame 59.

I have that problem with each core only getting 2 or 3 frames done and then getting stuck. Steffen is looking at that.

The artifacts are always about the same size in pixels no matter what res is rendered...

Here is a comparison of rendering at 1x versus 2x, 3x and 4x, then re-shrunk down...

2x or 3 x might be good enough for many animation purposes but you have to go to 4x to really iron them out.
