Hello away3d team, hello community,

I’ve been little active in the forums, but I’ve been working full time the last year on an interactive tool for people to create semantic 3d content/ web 3.0 websites on the flow in a natural language, build on Away3D. I’ve been focussed on the semantics part mostly so far, but now I’m getting to the part where I want to extend the word magic into 3D form magic. And to do that, I could really use the power of 4.x ... But I use 2d sprite stuff like textfields, checkboxes and 2d buttons a lot, and only recently discovered that these are not used as easily in 4.x yet… So I would like to ask you for guidance how best to continue:

For a real interactive feel, I would like for example a textfield to have a blinking cursor (functionality much like in http://www.naampetje.nl ) ...

I found this post about creating a bitmap of the sprite and using it as bitmapmaterial, and mapping mouse coordinates in the mesh back to the 2d sprite to create interaction… I believe this would probably be the best way to go for now?

If I keep track of all the changes in the textfield sprite, can I redraw the bitmap texture for every letter I type? and even for the cursor blinking? Is this doable performance wise?

Or is there perhaps a doable way to implement MovieMaterial alike functionality in 4.x with some help?
Again, I don’t mind going deep to build it, but my knowledge of the 3D parts of the engine is quite limited so far because the higher level methods were all I need, so I would need some help.

What path do you reccomend taking time and difficulty it would take to build it, and quality of expected endresult into account?
