it is very simple affect. I think we can add it next month.

I am sorry we have not fixed the shadow issue. We are going to fix it this month. And thank you for constant reminders about the problem.

Do you mean the Import section?

leaf fall is an old animation. It needs reworking before improving, unfortunately

It would make the job easier.
I can do this if I multiply 3 pictures horizontally in advance and load them into the program, add horizontal movement.
It’s a pity the program does not have coordinates for accuracy. Therefore, a lot of time is spent on setting the picture in the right place in the workspace.

I had many attempts to implement a similar effect for cartoon fire.
Alas, not one brush could not give the desired effect.
In addition, in the program, a shadow appears from the image when it is transferred to a separate layer. They fix this mistake for so long, but they never fixed it. They do a lot of unnecessary things, it would be better if they did what is really important.

No need for 3D.
I just want to add my sakura leaves.
Replacing the image would be enough))
And I also asked to make a Shine brush in one direction.
And layer grouping.
I’m looking forward to it.

Yes we plan to add this option. when better 3d support will be added to the program.

I think it can be made with the Drift brush. You can increase the speed, set random motion type and use timing settings to make it more natural.
