I’m using offline Collada to glTF converter. It works for non-compression gltf. But when I enable the compression (with option “-c Open3DGC”), Cesium failed to load the gltf model. Showing error :
“TypeError: Failed to execute ‘vertexAttrib3fv’ on ‘WebGLRenderingContext’: No function was found that matched the signature provided.”
The compression looks really good as it’s reduced about 50% of the size. Wondering how can it be used in Cesium?
btw, in the non-compression gltf, looks like the color information in COLLADA is missing, which result a simple white model with no color. This model doesn’t have any texture but just (vertex?) color.
