Hello! I'm sorry for the late answer. There's been a lot going on in my life in the past few months. I have been looking for VFX jobs literally all over the world but I can't find any. So I decided to go back to what I was originally doing: creating indie games.
I am currently releasing a cross-platform multiplayer game (a solo project so a lot of work beyond development like submitting it to the Steam / App Store and creating all the visual and textual metadata etc) "Afk "of VFX stuff. I have to heal my broken heart (I'm just having fun)
For color gradients, however, I only use a static (pre-rendered / serialized) image with Lerp. I recently had to update my operating system and format my entire hard drive so that everything is currently on a backup disk somewhere. However, I remember having an editor script for Unity that can be used to "serialize" standard Unity gradients into a small PNG file. This is how I create my history maps most of the time. I'll post the script here when I have time to restore my projects. I consider myself to be "Anti-Flipbook" Artists. Among all of the vfx I've posted here, none use flipbooks other than the fire loop I made with Houdini. All the others are basically some UV magic!
P.S: Check out the trailer for my game mentioned above if you're interested Hopefully it will be released on Steam and the App Store next month like this.
mini PVP is now available on Steam! Woohooooo!
