Bug has been reported, thanks!
About the scale it just change the pixel size. so if canvas is 400x400 and you set scale to 4, que exported frames will be 100x100 no 400x400.
First of all sorry the tool not works on your system but if you read the page:
"*Test DEMO and read the Limitations List before buying!!*"
This makes sure the game/tool works on your machine and it works perfectly with all the possible limitations or OS errors and give you an idea if worth purchase on your system. This is made to avoid scams like purchase and ask for refund due not works when they do.
Btw, about how to ask for a refund:
For perfect loops normally with pressing the lopp animation should work, just press at the end of editing. I mean, if you press loop animation, but after that you still do some value changes you will have to press again.
If you still have some issues check the particle life to see if match with the frames to render. Also check the examples of rain, radial stars that does the same thing you want to do in a perfect loop to see what is causing the problems.
I think now i understood you. So you want a particle effect that starts with nothing creating particles and then a way to get a continuous loop.
No idea how to do that sorry.You can create burst animation and loops. But create a burst animation that ends just to add the looped one and this two one fits, i don't know. Maybe there is a way but actually no idea.
Still i don't know very well. If your loop animation is 60 frames, the time to the animation get loop , this means start again , will depends on how much fast you set in your game that animation ¿?
And what you need the time? If you need for execute some event you can say = On Animation finished -> Do X, or ANimation is on Frame X(The ma N frames your animation have) -> Do X ¿?
GIF export option is not supported on MAC, only on windows.
If you are using Windows, check if the folder/path on you have installed there is some space, but it should be already fixed just let you know.
Btw, GIF and Json export options are WIP. The option to be used is .PNG spritesheet that works on any OS and engine.
You always export at 1:1. All depends of pixelation you set.
If you have a 4 pixelations for H/w and the image is 512x512, the exported image will be 128x128, due 512/4= 128. So exports at 1:1 to be ready to use, in games or whatever, so you not need to resize, that all people requested so i made in this way.
And yes to zoom only works with mouse wheel sorry.
You can att he moment add custom particles clicking on "sprite" button on the right to select one of the visuals have to appear there.
The problem was hard to solve due we wanted to people add custom folders with their particles, but due Mac filesystem was unable to do it right, so we changed and we gonna add that images inside the app no folders so can be acceses via Mac with no problem.
Sorry for delay, hope to release the new version with this and other bugs fixed!
It should appear if you bought it. Looks this tutorial, is from another game but all works in the same way:
