Almost all effects can now be adjusted in size using the scale feature of the CUA in VAM. Due to implementation techniques of the waterfall and firework effects in this pack, these specific effects cannot be changed in size. I discovered this issue when testing the waterfalls and fireworks so I left the original versions in this pack. There are a few effects in which scaling in size may not produce desirable results, but I left the option open for you to try out. For many effects, such as the portal below, the scaling feature should work out nicely.
* Twister 1 has known issues but I left it in this pack, Twister Version 2 works fine.
