Thanks ! Pretty straightforward fix but I wasn’t sure that the null _animationRegisterCache was the real culprit or just a symptom, so I didn’t modify it myself

Regarding the Skybox issue, I’m afraid you’re right… Sadly there’s also a bug in Away3D that prevents two View3D using the same Stage3DProxy to blend together if one of them has a Filter3D. (It’s been reported on github for future record)

Otherwise it was a perfect workaround

Thanks again ! Away3D and EffectHub+Sparticle are amazingly useful !

another very useful tutorial:

A wonderfull project.
I’m a newbe in particle systems, I read the tutorials in the site, could you tell me some good books or web sites to deeply undestand how to create a good particle system effect?

The holidays are almost here and that means it’s time to hold a contest to celebrate!
Sparticle is a profession GUI tool, based on one of the most popular 3D engines in Flash, Away 3D. This high-performance and GPU-accelerated tool is ideal for game-effect designers who want to develop complex 3D effects for their games.

This contest is open to worldwide natural persons who, at the time of entry, are legal residents of their countries.

the contest will begin on January 15, 2013 and will end on March 1, 2014. Entries for all prizes must be received by 11:59PM, CST.

1st Prize
A brand new 16GB Wi-Fi iPad Air (or $500 in Amazon Gift Card)

2nd Prize
A brand new 16GB Nexus 5 (or $350 in Amazon Gift Card)

3rd Prize
A brand new Kindle Paperwhite (or $120 in Amazon Gift Card)

There’s been a nice income of great effects because of this contest. That was definitely a good idea !

I have a possible performance suggestion. In this tutorial you said:

When alphaBlending isdisabled in the normal mode, theobject is rendered as an opaque object.
[...]
Although it is not possible to cause the GPU to always render the opaque objects first (rendering order is determined by the index buffer which can be considered to be random), [...]

I stumbled upon this article from a Chromium developer who says:

The primary goal of this prototype is to draw the entire sprite field with one draw call. This might seem impossible, because the sprites require alpha blending, so they must be drawn in a particular order. It is a little known fact (I wasn’t sure of it when starting to write the code) that OpenGL actually guarantees that triangles will be drawn in order, from first to last, when drawArrays and drawElements are called. Apparently GPUs contain quite a bit of silicon (the Render Output unit, or ROP) to provide this guarantee. The only major remaining problem is how to avoid the per-sprite texture bind. The basic idea is to send all of the sprite sheets for the entire sprite field to the fragment shader, and have it somehow choose which one to display for any given sprite. [...]

Maybe you can figure something out of this to make EffectHub’s particle effects even faster ?

Edit: Oh crap, you’re using Flash only! drawArrays and drawElements possibly only exist in WebGL ?
By the way, do you intend to make EffectHub and Sparticle support ThreeJS at some point ? Just curious

Hi SuperSam
So careful of you! It’s a translation error.  The accurate description should be

Although it is not possible to cause the GPU to always render the opaque objects near the view first (rendering order is determined by the index buffer which is predefined and it’s costly to update it before every drawing)

Thanks for correcting this error. I’ve update the original article.

I don’t have the plan to make Sparticle support ThreeJS at some point. Seems that supporting Away3D-JS is much more straight.

Ok that’s good to know. Internet, the place where stuff has to go through 3 languages before you can understand anything :D

Sure is! I thought you intended to extend support to other engines ever since you renamed awayeffect to effecthub and changed the editor name to Sparticle
If such was your intention, then ThreeJS made sense because of its consequently larger user base (although I don’t have numbers to back that up)

Anyway thanks again for creating this repository and tool

Hi!
Sparticle is a great tool!
But is it possible to [Embed] .awp effect into AS3?
I don’t want the effect to be loading over the web, i need it embedded into my AIR project with all dependencies (textures, etc).
If it is possible, is there a tutorial?
