Making Minecraft Tnt Mods Look Cleaner With Big Explosions

I assume this is a mod of your own making? You should share a link to the code, and also give a little more detail what you mean by "make it look cleaner", as that could mean something different to different people.

True Ending Ender Dragon Overhaul: Ender Dragon Not Perching

This is most likely caused by Epic Fight. With Epic Fight, the Ender Dragon sometimes lands on the ground and attacks with its claws instead of perching on the portal.
I had the same issue, so I made a small mod that removes the dragon’s invulnerability so the fight doesn’t get stuck. https://www.curseforge.com/minecraft/mc-mods/epic-fight-true-ending-compatibility
