I've done some more testing and run some render time comparisons between Anim8or V1.0, Anim8or build 1329 with multi-threading, and Carrara.  It's tricky to run a fair comparison with Carrara since it is an entirely different package with a different set of parameters but I have attempted to match the AA, materials and lighting as close as possible on a quick still life with lots of lights (14), ART attributes and soft shadows.  Materials and lights in Carrara have been set to match Anim8or as closely as possible, and the model is identical.  Renders are attached and times are below:

Anim8or V1.0 AA100: 50m 11s
Anim8or V1.0 AA100 (fast AA): 11m 10s
Anim8or build 1329 AA100 multi-threading on: 5m 47s
Carrara: 9m 5s

There are some minor issues with the 1329 multi-thread render (some previously noted):

  • Graininess in the lower-right of the glass ball
  • Apparent lack of AA on objects visible behind the glass ball - some jaggy edges (may be the same issue as above)
  • Slight step in shadow at near corner of wooden ramp, though it is actually more pronounced on both V1.0 renders

Aside from this, the handling of shadows in general and the quality of the lighting is significantly better in 1329 than V1.0 and, remarkably, rendered quicker than Carrara.  This isn't a 'Carrara vs Anim8or' thread by any means as both have their advantages (Carrara for its massively powerful materials engine, Anim8or for it's workflow and simple UV editor), this comparison is only about rendering times.

This is a game changer!  Rendering speeds are fantastic, attached took about 2 minutes with AA at 100 on i7 quad core (8 threads), image size 1920x1080.  No problems to report at this stage, testing animation at the moment.

Trevor: You are correct. Your CPU has 8 multi threaded cores for 16 threads. Anim8or currently limits the max thread count to 8 but I'll increase that to 16 in the next build.

(P.S. Can I exchange CPUs with you :) ?)

I have 2 physical cores and 4 logical cores = 4 threads. I suspect that you have 4 physical cores and 8 logical cores - that's what Intel calls a "8 core cpu".

Erm... no... I have 8 cores, 16 threads, Im not mistaken :P

Hmm, looking at the cores, it would seem that they are all doing something since right before pressing render they were all more-or-less idle, however only 8 red lines ever show up on the preview.

maybe Im missing something?

Ok, so doing some tests with affinity and priority it seems you made a comment earlier that less cores could be faster, it seems your right, limiting to the first thread of each core actually works out faster than allowing all threads to run.

Steve: these are not problems for me but I noticed recently and while you are in ART-

#096-014 - ART Renders Don't Show Panaroma Backgrounds

I think there is also an issue with image background.

A second camera does not show the panorama in the work space or rendered view.

so, on your dual core, how many threads do you run? 2 or 4? (Since hyperthreading makes windows think you have 4 logical cores)
I have 8 cores, 16 logical cores and not all cores light up, only 8 do at a time. (obviously some cores also run other processes like windows, but they are not full)

Trevor: it doesn't really help to use more threads that there are in your CPU. If your CPU isn't 100% busy it's probably waiting on memory (i.e. there is more data being accessed than will fit in the CPU's cache). It might even speed up the render to use fewer threads, depending on the data set.

On my CPU (2 hyper threaded cores, 4 threads total) most renders use 100% of the CPU.

well, this is all rather exciting!  unfortunately i'm in the middle of a really hectic fortnight (and away from home for most of it) so i can't test this update straight away, but i'll give it a spin as soon as i'm able
