I'm trying to simultaneously apply several types of EffectShaders to the player, based on certain conditions like taking a large amount of damage at once.

However, every time I apply a new shader, the existing shaders seem to get hidden away, and will only come back when the new shader's effect expires. Is there a way of allowing multiple shader effects to be visible on the character at the same time, or is this a limitation of the EffectShader entity?

All I know is stacking shaders on top of each other will impact performance if too many are stacked.

This is not a problem for what I'm doing, I'll only be applying 2 or 3 at once. But your answer implies that you can have multiple shaders visible simultaneously, could you provide more details on where you got this information?

While, I've never seen two different shaders applied to the character, yes you can stack shaders of the same type at least, over and over again.

Are you using this: http://www.creationkit.com/Play_-_EffectShader

or trying with multiple magic effects with shaders?

I was applying multiple spells to the player, each spell having its unique magic effect and associated EffectShader.

I'll try applying the shader directly with the Play function, and see if that allows for what I need it to do.

No, shaders still overwrite each other with your method.

I'm confused as to why the Play function even allows stacking, if you can only stack the exact same shader over itself... I can't really imagine many possible uses for that.
