I worked recently on a project that required 3D animations. With my brand new Adobe Flash Professional CS5.5 I started building some cool animation tweens with 3D transformations. Everything looked good until I came across with some weird problems.
Sometimes I published my movie and I saw some 3D animations not being rendered properly or not being rendered at all. For me the most important thing is to be 100% sure that the content is going to be displayed fine for the users. It seems this problem happens when we publish the movie and not when we run the published SWF file.
Playing around with this bug I found out, at least, how to deal with it. In my case I have several scenes on my movie. Don’t know if this bug happens as well in one single scene. What I did was opening every scene and move the playhead through out the timeline and then when I published the movie again… the problem was gone! and the movie is being displayed fine as it should.
It seems there is something wrong with the tweening and the 3D that is not properly processed when we publish.
Hopefully Adobe will solve it soon!
