A few questions about UniSWF

If anyone has experience with it, I'm noticing a few things which I'm not sure about. I made a flash animation made up of 1 symbol with two other symbols inside it. The layout is as follows:

• A circle converted to symbol in the main timeline.

• inside this symbol, two other shapes: another circle exactly like the first, same position and everything, as a symbol too. And a square off to the right of the original circle symbol.

• In this container symbol's (the initial circle in 1.) timeline, I animate the scale of the second circle symbol and animate the square symbol's alpha (but the square stays otherwise put, off to the right of circle symbol 1).

I then export all three symbols for AS3 to use in Unity via UniSWF. But when I load the swf in unity into a MovieClipBehaviour I notice that:

1. The transform seems to be off. I place the object at 0,0,0 and use whatever Unity native mesh as reference and the SWF-based object does not align centered with respect to the Unity object at 0,0,0.

2. As the SWF object plays, the transform handle seems to drift back and forth.

3. In the inspector, I also see 3 materials for the SWF object. I'm assuming these are one for each of the three symbols and they are probably changing textures once each per frame?. I notice one of them seems to be constantly added and removed from the list of components in the object. Maybe the one that gets removed is the one for the square symbol when its alpha drops to 0 in the flash animation?

4. In the case of a InteractiveMovieClipBehaviour, even though it creates a collider the size of the quad, clicking anywhere on the screen (not just inside the collider) triggers whatever event I register with the corresponding SWF MovieClip.

I'm wondering if these behaviours are normal. 3 I'm only concerned cause of efficiency (repeteadly adding and removing a material at runtime). But 1 and 2 are kind of bad, since they prevent me from positioning the object exactly where I want it by just thinking about coordinates. And 4.. I must be missing something.

My guess for 1 and 2 is I'm messing something up in terms of anchor points in the flash file itself, but I'm not sure since flash is not my thing really (I'm a software engineer).

Thanks!
