High-resolution Particles, or Beautiful Effects

Hi. I want to make a beautiful effect in my mod, and as well as I know, these effects have been created using high-resolution particles, but when i try to do so in MCREATOR, my particle looks pixilized, due to the fact that the maximum resolution is 512x512, and when I try to put my effect texture (animation strip), to workspace folder, it looks like a corrupted texture in game. I would like to make an effect like aura node in my favorite thaumcraft (https://m.ftbwiki.org/images/thumb/7/77/TC4_Node_Goggles.png/300px-TC4_…) , or nitor https://static.wikia.nocookie.net/minecraft_ru_gamepedia/images/f/f7/Ni… . Please, help me!
