Unigine::ObjectMeshSkinned Class

Header:	#include <UnigineObjects.h>
Inherits from:	Object

This class is used to create or modify skinned meshes.

Creating and Playing Animation#

To add the animation to the ObjectMeshSkinned and play it, do the following:

Set the number of animation layers with the setNumLayers() method. There is only one layer by default.
Enable the layer and set the animation weight for blending by calling the setLayer() function.
Add the animation .anim file by using addAnimation() or setAnimation() functions.

Notice

When you import your model with animations from an FBX container, the following path to your *.anim files should be used: <path_to_your_fbx_file>/<file.fbx>/<your_anim_file.anim>

For example: object->addAnimation("models/soldier/soldier.fbx/run.anim");

The recommended approach is to use the Component System and provide the guid of the .anim file.
Source code (C++)
```
UGUID guid = FileSystem::getGUID(anim_asset.getRaw());
int animation_1 = skinned_mesh->addAnimation(mesh,guid.getFileSystemString(), "run");
```
Play the added animation by calling the setFrame() function for each animation layer.

Blending is performed between all layers. The contribution of each layer depends on its weight. Also, you can optionally define single bone transformations by hand, if needed, using either setBoneTransform() or setBoneTransformWithChildren().

Usage Example

The following example shows how to blend 2 different animations assigned to a mesh. In this example we use the mesh and animations from UNIGINE samples located in <UnigineSDK>/data/samples/animation/meshes and <UnigineSDK>/data/samples/animation/animations folders, respectively. Animations are added by using the addAnimation() function.

Below you'll find an example of using the Component System to access animation assets.

Create a component for controlling loading of animations and generate a property for it.
Assign its property to the target controller node.
Assign desired animation assets to the parameters of the property by using the Editor.

Assigning animation assets to property parameters via the Editor

Implement logic of creating a skinned mesh with the specified animations. The complete source code:

Updating Bone Transformations#

Some of the methods require to update the animation data before the renderer makes its update and actually draws the skinned mesh. Such update allows to get the correct result of blending between the frames and layers.

The execution sequence of updating bone transformations is the following:

Call the method, which sets the update flag. This flag shows that the instance should be updated.
Update the bone transformations by calling proper functions. These functions check the flag and if the flag is set, they calculate the transformations and set the flag to the default value.
During the rendering, the engine performs animations and transformations which were calculated on the previous step or recalculates them, if the update flag has been set. If calculations have been performed, the flag is set to the default value.

If you try to update bone transformations before you set the flag to update, functions will not calculate new transformations and the engine doesn't perform them.

When you change the transformation of the bone, you should notify all skinned meshes which use these bone about these transformations to update the mesh. When you change transformations of a bone, skinned mesh instances get the flag to update. When you use the setFrame() function, you set necessary transformations for the specified skinned mesh.

Instancing#

Surfaces of identical skinned meshes which have the same materials assigned to them and the same number of bones attached to their vertices are automatically instanced and drawn in one draw call. The instancing flag is enabled by default (see corresponding console commands).

The data buffers for instanced objects that store bones transformations are limited in size; therefore, if skinned meshes have many bones, only a few meshes can populate the instance data buffer to be drawn in one draw call.

NoticeThe higher the number of bones and the more bones are attached to one surface, the less robust instancing will be.
