# Guidelines

The scale must be defined in meters.

The asset must face the Z-axis using the standard Unity axes (X, Y, Z).

All model elements must be placed in an Empty element (root) and positioned so that the root is at the base of the model. (The root is the point where the NFT rests).

The velocity of the model is 1/4 the height of the model (_e.g. if the model is 1m high, the velocity of movement will be \~0.25 m/s_). Based on this adjust the animation speed accordingly.

{% hint style="info" %}
**Tip**_:_ You can override this calculation by inserting _Empty_ elements in the root of the asset: **"anim\_speed"** and **"move\_speed"**. The scale of these elements will be the value used in the app for the animation speed and movement speed of the asset.
{% endhint %}

The main animations that are used are "Idle" and "Walk". The model must contain them in its list and they must be named in this way. It doesn't matter if they are in upper or lower case.

The first 4 animations that are found in the list (excluding "Idle" and "Walk") will be added to the list of animations that can be used by the asset, this functionality will be implemented in the "quick menu" of the animations.
