war3 beta models

I can import most models fine from the war3beta pack
except for 2:
Corpse Explosion
DeathandDecay

I tried to let them into their imported path, I also tried changing their path to an already existing unit/ability effect. Still, nothing

Anyone can help me???

Have you tried to change the Death and Decay Beta stuff to the path of the existing one??? that may work

well DeathandDecay.mdl does not exist in the game, only DeathandDecaytarget.mdl
as for corpse explosion, there is no ingame model based on CE
