Tiles from GLTF missing texture #13

Closed ManosAgelidis closed 1 year ago

ManosAgelidis commented 1 year ago

Original GLTF has a texture assigned and is pre-tiled as you can see in the picture Screenshot 2022-11-08 135501 I am trying to generate a tileset based on the GLTF, after executing the command

python main.py tileset path_to_gltf.gtlf

the tileset.json as well as the .b3dm files corresponding to the tiles are generated successfully. Upon loading the 3D tiles in a 3D viewer the texture is missing from most of the tiles. I also tried loading the tiles in a Cesium-based viewer and the textures are also missing. What would be the solution here? I saw that there are some recent commits addressing texture issues, maybe this problem is related? Let me know if this information is enough, thanks for looking into it.

Hi, thanks for looking into it so quickly. I created a minimal example gltf that shows the problem. I will test on my side to verify the problem is gone.

Hi, seems the issue is still there with the latest changes. image

I created a minimal gltf which is just a box that has been sliced into 4 sub-boxes that uses the same texture as the original gltf that I used. Since I cannot upload it on github I shared it from my google drive. Link to the model. Hope it helps, thanks for looking into it!
