# Visual Effects
The ODK uses the `BPC_ODK_NiagaraEffectsManagerComponent` to play local and replicated effects on characters. The `BPMC_ODK_GucciTrailHandler` is an example showing how we add and remove effects to characters that own a Koda pendant NFT.
Inside `BPMC_ODK_GucciTrailHandler::TryApplyGucciTrailEffect`, we use the `BPC_ODK_NiagaraEffectsManagerComponent` to add the Gucci Niagara visual effect to both characters feet using `AddNiagaraEffect`. It's parameters are as follows:\
\
Niagara System - The Niagara system to add.\
Socket - The socket on the character mesh to attach the Niagara system to.\
Relative Transform - The transform which should be applied to the Niagara system relative to the socket. This lets you offset/rotate or scale the visual effect in relatioin to the defined socket.\
Is Persistant Effect - If true, the visual effect will play continuously until removed. If false, the effect will run once and then be automatically removed.\
Replicate - Should the effect be visable to other players as well.
`AddNiagaraEffect` returns an Id for the effect that should be used when attempting to remove the visual effect. An example of this can be seen inside `BPMC_ODK_GucciTrailHandler::RemoveGucciTrailEffect` where`RemoveNiagaraEffect` is called with the relevant EffectId.
