Animation is the art of bringing life into things. And there’s no better way to make you scene more lively then adding some animations to your 3D models. There are a couple ways to do it though: through object animation or through a rig (skeletal animation). Object animation is best for simple models, such as a bouncing ball, a spinning globe or a floating chair and it doesn’t need an armature. ...
To enable collisions between a 3D model and users of your scene, you must create a new object to serve as a collider. Without a collider, players are able to walk through models as if they weren’t there. For performance reasons, colliders usually have a much simpler geometry than the model itself. Colliders currently don’t affect how models and entities interact with each other, they can always overlap. Colliders only affect how the model interacts with the player’s avatar. ...
3D models have a mesh composed of triangular faces. These faces meet each other on edges (the lines along which they touch) and vertices (the points where their corners join). Scene limits # All 3D models in your scene must fit within the limits of its parcels. If they extend beyond these limits when running a preview, the meshes will be marked in red and bounding boxes will be highlighted in white. ...
Materials are embedded into a .gltf or .glb file. This document refers to materials that are imported in a 3D model. For materials defined via code to apply onto primitive shapes, see materials . 📔 Note: You can’t currently dynamically change the materials of a 3D model from your scene’s code, unless this is a primitive shape. Shader support # Not all shaders can be used in models that are imported into Decentraland. ...
3D models are imported into decentraland in glTF format. There are a number of supported features that these models can include. This section goes over ways to make them compatible with Decentraland and best practices. See Set entity position for information on how you can configure a 3D model in a Decentraland scene to set its position, scale, etc. Keep in mind that all models, their shaders and their textures must be within the parameters of the scene limitations . ...
