People were suggesting to bring ESF a cvar that limits how many transformations a player can do. This plugin will not allow transformations at all unless you set esf_allowtransform to something else than 0. I will update this plugin later when 1.3 comes out to limit the 1.3 transformations.
Note: I will not support EVM's transformations. Seeing that is a third party extension and not ESF itself.
To run this, you only need AMX mod X installed with this plugin linked in the plugins.ini
