Hi :D
Do you know Player Revive ?
It has incompatibilities with Dissolution.

1 - In solo, if you open your game to LAN, if you die, the game crash.
2 - On a server, the game doesn't crash, Player Revive works..at 50%: the UI doesn't show up.
You're stuck on the ground, waiting the end of the timer, then, Dissolution play his role.

So, I suggest the idea that Dissolution wait the real death of a player, after the timer of Player Revive, just before the death screen of Minecraft want to show up, to start his work, activate his blue shader ect..

Do You know Metamorph ?

Problem:
If the player is morphed, the model of the creature doesn't disapear.. not entierely..
Here is what happen with the morph of an Enderman in azombie, and the morph of a Golem in a skeleton..

The player revive issue has already been reported and should be fixed on their side.

oh cool '-'
other thing..
a Golem in soul form, is very very slow..
It's like moving in water, where he's very slow.
could the Soul Form.. I don't know, prevent metamorph behavior ?

Depends on how the mod is made. I guess I could force the player to revert to a human when in soul form.

that would probably do the trick, but what about forcing the player to retake his morph shape when he is alive again ?

Meh, you loose your body, you loose your morph, sounds fairly straightforward

yeah, I understand that, for a normal minecraft context..
But I use metamorph on a rpg server, to make different playable races ^^'

Metamorph is not on a supported version anymore, but the cause of the incompatibility is fixed in Requiem.
