FAQ: Unity SDK

Questions about our Unity SDK? Let's solve them!

How do you manage collision while playing user-generated emotes?

As detailed in Kinetix Emote Standards, all our emotes are following very constraining standards in terms of axis to limit all potential collisions.

Moreover, our SDK embarks a Root Motion technology that you can implement to prevent collisions when playing emotes.

How do you manage interpenetrations with user-generated emotes and avatar mesh?

Every emotes distributed through Kinetix SDK and API can be optimized with the "contact aware retargeting" that retargets emotes on the target rig before their distribution.

How is retargeting handled?

For optimizing user experience, retargeting process is queued as explained in Animation System - Unity. It means that we ensure every user-generated emote that appears as loaded on the player's side will always be available to be played by them at anytime. Emotes that are still in the queue will appear has been loaded for players.

Will Kinetix SDK affect my game performance?

Our Kinetix SDK have been developed to solve issues you are experiencing when integrating the User-Generated Emote feature into your project. Among different aspects what we optimized most is: network and memory.

We went through the process and developed a solution that facilitates dmote integration to a point where you will only have to focus on the fun of managing user-generated emotes in your project.

How many animations can be added to my game and what is the impact on the memory?

With our SDK, there is no limit, you can add as many user-generated emotes as you want! Kinetix's SDK has been designed to optimize memory usage.

How do you solve spikes of gamers and associated server sollicitation?

We thought of multiple solutions as historically the animation where only synchronized based on the state and not the poses..

The SDK sends serialized poses through network to limit the charge on spike as it only requires users to download a pose for each active emotes on several frames.

The data you will send, the frequency and the number of players at peak will impact the bandwith of the server and your users.

How can I optimise the SDK for usage spikes ?

For optimisations purposes (especially for mobile and low connections) considering you can have up to 500 gamers at same time in the same room, Kinetix recommends the following optimisations:

  1. Reduce Serialized Data: During serialization you can choose which data you want to serialize. This can be updated through the KinetixCore configuration with an instance of KinetixCore.Networkconfiguration.

  2. Reduce the frame rate : Reducing the frame rate will reduce the amount of poses sent over time and will result in lower bandwidth charge. You can test out the quality for lower Frame rate but we recommend to keep a frame rate at a minimum of 20.

  3. AOI (Area of interest): While receiving serialized pose from clients, you can determine which other clients will need to apply those poses based on their positions, or if they are visible for example.

  4. Omission : During spike, we recommend to keep a small amount of user networking emotes. In that case you can setup a limit of N players playing an emote simultaneously handled by your network and send a maximum users emote poses based on your server bandwith limitations.

How do you manage big amount of gamers connected at the same time?

To unlock self-expression in games, Kinetix had to make the necessary to allow as much players as possible to play Emotes at the same time! When hundreds of players use their loaded Emotes at the same time our smart networking solution optimize peer-to-peer connection. As detailed in Network - Unity SDK our SDK only extracts poses of played Emotes and shared that reduced pose information with the other players.

Eventually, we allow you to decide the memory allocated to the Emote networking so you can optimize it based on your needs. From our various tests we identified 50 Mo as recommended memory.

Does the SDK work with Smarfox Server?

Regarding the transfer of poses, it is possible to get the pose in byte[] and apply it through our SDK.

While getting a Pose it is possible to transfer this data through your server and redirect it to the other needed peers.

While other peers receive the pose (byte[]), you can apply the received pose of the peer through our SDK.



The Photon samples are juste exemples of an implementation through a network solution, but can work in a agnostic way through Photon, Unity Networking or even SmartFox Server.

How can I clean the emote inventory when switching to production?

When switching to production, you have to request an Unlimited Key (go to Developer Portal for more info). Once you log your Unlimited key in Kinetix SDK, your inventory is automatically cleaned as no Emotes are associated with the new Unlimited key.

How do I deregister / remove emotes?

You can remove user-generated emotes from a player's bag through your Developer Portal account. Head to the UGC Moderation tab to do so, and follow the flow.
