If you need to find the entity handles for models composed of multiple parts organized into a parent-child heirarchy, you need to set the namestrings of the individual models in the modelling program and then load the model using LoadAnimMesh.
You can then use FindChild to search for the entity handles of the individual entities, using the names you've assigned. Once you have the entity handles, you can use them to set the alpha.
