I am attempting to animate a two minutel piece and am having major issues. I am creating symbols and using them in my tweens. The symbol is usually fine for the first couple of keyframes then the preview changes from characters to rectangular blocks. When I test the animation it is fine, but I am unable to make adjustments because there is not an accurate preview of the symbol. This project needs to be done in the next 48 hours and I am going nuts trying to figure out why this is happening. It also keeps throwing out or disabling my audio file.
I am working on a 6 month old MacBook Pro, loaded with memory and fastest processor available at the time.
You sound like someone who is not novice with Flash/Animate, so you should know that what you report is unusual.
First of all try to re-set the program, by deleting config.
HD\Users\YourUserName\Library\Application Support\Adobe\Animate CC YourVersion\YourLocale\Configuration
Animate has to be closed when you delete it.
If that does not help, in a situation like this, you have to try is to work on a different computer for a while. It could be that your new Mac is developing some kind of a RAM fault.
The next thing to try is a different version of Animate, if behaviour is the same on a different computer.
Finally it can be something with your file which you will have to identify by elimination.
Always save copies of your files and have backups.
Animators are not firemen and noone dies if you miss a deadline, so relax.
I see. Fingers crossed you finish the piece on time, mate!
Have you tried switching to a different preview mode, like Full or Anti-alias from the View menu?
There have been many people complaining about sluggishness with retina displays. Animate seems to not be dealing well with high density displays. Maybe you have come across some of those unpleasant issues with the screen buffer...
I've seen this before! You are using imported bitmaps correct? I have found that when high resolution bitmaps are imported, when you scale them down inside of Animate, at a certain point, they get rendered as solid color squares. if you re-export the images from say Photoshop at 72dpi and/or smaller in terms of width and height, this will solve the issue - keep in mind if you overwrite the existing assets in AnCC then it will mess up your existing animation because the images inside the symbols will get updated (smaller).
