Some of the software and tutorials for the signature file of the wall ash removal are great, and the more detailed the tutorial, the better.
Dear, this software is called AE, which is After Effects. It is a post-production software of Adobe. Wall ash dropping is an engineering document, which needs to be downloaded. AE can be downloaded by Baidu once, and it is recommended to download AE CS4 green version. It's quite useful AE wall ash-falling engineering documents will be available as soon as Baidu searches ~ ~ Please adopt them if you are satisfied, dear ~ ~ Thank you. This is the picture.
