DIRECTION_ALIGNED doesn't work in Irrlicht

Hey.

I'm using SPARK 1.5.5 and I tried to rewrite Explosion example to work with Irrlicht (basically just change Quad renderers), and it seems that DIRECTION_ALIGNED orientation doesn't work. This is how it looks:

(note the thin sparks, they should face their direction).

Is it a known issue? How can I fix it?

Well, this is not a known issue, can you post the code ?

Also there is SPARK 2 out there for some years, there is no zip archive but a svn.

Thanks for your reply. Are there any good reasons to switch to SPARK 2?
I tried to write a simple code which would reproduce this bug, but it seems that outside of my project it works. Do you have any ideas what could cause this? Debugging it will take ages, since my project is ~60k LOC, so there are many things that could potentially cause it, different camera settings, different Irrlicht device settings... I don't know. It seems that particles have like 45 degrees offset.

Ok, found the problem. I was setting flags incorrectly.

Btw. Is there any way to scale whole Group? So that zones and textures are scaled. I'd need it for small explosions and big explosions.

Good catch, yeah 60kLOC is a bit too much for this forum^^

Well, I will see more in details, but if you're using Irrlicht you could change the transformation of the node with a bigger scale (or similar concept if you're doing native OpenGL).

SPARK2 is more powerful on a number of points, and adds the ability to automate some parts of an effect. But if you have SPARK1.5 up and running in your project I think the simplest is just to continue using it.

Ok, thanks.

I wish there was a function like ->setTransformScale() just as ->setTransformPoition() and ->setTransformRotation().

Is there any way to correctly rotate a Zone? Using ->setTransformRotation on a whole Group looks good as long as one uses symmetrical Zones (like spheres) - then whole 'Group' is rotated well. But if I use AABox Zone, then rotating whole group doesn't seem to affect the box itself (it always points at the same direction), am I doing something wrong?

Here is a complete example (rotation functions are marked as /////HERE, none of them seem to do anything):
