I hope it is ok if I add my issue here; it seems to be closely related to this one as well as to this one.
I’m also one of those guys who tries to switch from Google Earth to Cesium, so I’m a complete beginner. I tried the following workflow: Basic data from OSM -> modelling in CityEngine -> export as collada (.dae) -> convert to .gltf -> include/show in Cesium. My first try was successful and I was able to include many individual models in one “main model”. However, when I tried to select individual models (in my case buildings), I got only a transparent skeleton-model (see attached file model_image.png, on the left how it should look like, on the right how it looks).
Since the .dae looks good (Mac Preview, A360 Viewer) I think, referring to the Tutorial, that the problem is somewhere later (i.e. in the converting process).
I tried: a) the online converter ; b) converter build v0.8 and finally, due to this post also c) the “main” converter. In method b) and c) I used also nearly all available options. Due to this post I changed as well
TEXCOORD_2 since I thought that it could be maybe the other way around in my case ;). The effect is always the same and I get the shown result (see image). The only difference is that I receive this message in method c: “WARNING: unsupported opaque mode:RGB_ZERO fallback to A_ONE”. So maybe that helps?
An example of a .dae file is attached.
Any help is highly appreciated!
