This shard takes the glTF model (specified either in the Path, Bytes or Copy parameter) and outputs a drawable object which can be subsequently added to the drawables queue for the render pipline.

Details

This shard can take a table as input that contains the following keys with the following values: - "transform": The 4x4 transformation matrix that contains the translation, rotation and scale for the glTF model to adopt. - "materials": A sub-table that contains information to modify the materials of the glTF model. - ["bone1" "bone2" "bone3"]: A node can be modified by passing the bones path as a sequence of strings as the key and a sub-table containing the parameters to modify. Eg.

{
  ["rootNode" "spine" "upperBody"]: {
    scale: @f3(2.0)
  }
} GFX.glTF(Bytes: asset/my-model)

The sub-table that can be provided in the materials key of the input table will take the following format: "key" : value where the key will be the name of the material to modify and the value can either be: - a material object to replace the current material of the glTF model with, or - another sub-table which contains information that can modify the current material.

The sub-table that can be used to modify the material can take the following format: - "params": a table containing keys representing parameters specific to the material and values with their respective types. Providing the a value to a key here will modify the value of the parameter in the final glTF model.

The input table can include keys representing nodes to modify. The keys can be a sequence of strings representing the nodes to modify. There can also be multiple keys with different sequences of nodes. The values for these node keys can be a table with the following keys: - "transform": A 4x4 transformation matrix (overrides individual components) - "translation": A float3 value for node translation - "rotation": A float4 quaternion for node rotation - "scale": A float3 value for node scaling - "params": A table of node-specific parameters (if applicable)
