Trevor: I just posted build 1330 with max-threads of 16. Give it a try!

AlecJames: Backgrounds of all kinds (Panorama, Image and Cube Map) should work for all camera views in all renderers in build 1330.

selden: the int Attribute MaxThreads sets the maximum number of threads. So if you have a 4 code CPU you can set it to 3 to leave a core for you to use while it's rendering. Alternately, you can set it to -1 to use all but one thread, or -2, etc.

Raxx: the main difference with the multi-threaded Fast AA for your scene is the way Anim8or handles soft shadows.

Previously Anim8or would sample sqrt(n) samples for n sample anti aliasing and see what the max color difference was between the samples. If it was too large, Anima8or would take another sqrt(n) samples. Then if the color still wasn't converging fast enough it would sample the full number.

Now the color difference isn't used because highly varying textures could cause a slowdown. Instead Anim8or uses a mask of what lights are visible for each sample. If it is different for the first sqrt(n) samples, then Anim8or samples all the rest. This works very well for normal shadow edges and soft shadow edges that aren't "too soft", i.e. the number of pixels that are partially shadowed is small. You scene has several soft shadowed lights that are very close to the objects which means a lot of pixels are softly lit. So Anim8or sample all samples for them. Since you are using 100 sample FastAA this adds a lot of time.

I have a more sophisticated algorithm that I want to try for later builds that should make much smoother soft shadows with fewer samples. It involves filtering the light separately from the surface material. I don't know when I'll have it ready so keep you fingers crossed!

Trevor - what does it mean "has corona as close to Z-Near as possible"?

oh, haha, I know we can do it manually, I was meaning more a An8 feature for Steve :P, it would certainly make ART unique.

haha, I couldn't resist testing my old lightsaber in the new ART

10:33 for full self illumination (DIR) with 64AA - there are no "Lights" in the scene

Final image has corona as close to Z-Near as possible.

Trevor: Definitely possible, I'm planning an animation test with multi-threading and will include coronas :)

Those Christmas lights just scream "Corona required" :P

hmm, actually, just having a think about it, how hard would it be to have 2d sprites attached to the Z-Near and locked to the on-screen position of "target" nodes?

Bit more of a "Game Engine" feature than a "3D Modeler" feature, but it would be great for renderings (scanline or ART)

Agreed, they compare very well indeed and the speed is really impressive.  If anything I think the Anim8or 1329 render has the edge, there is a richer saturation and it's a more pleasing render overall.

ENSONIQ5: Nice comparisons. I'm really pleased at how well the latest Anim8or compares to Carrara. Carrara's lighting and glass effects are noticeably better, but overall Anim8or's speed and soft shadows seem to match Carrara's.

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 :) ?)
