I have been using Cesium ION to convert
.obj files to 3D tiles but have noticed that there are cracks between the different texture patches. This does not seem to be the case if I use Cesium ION to convert the
.obj file to a glTF file (or if I view the
.obj on Cloud Compare).
Below are images of the same section of the Model as 3D tiles and as a glTF. You can see the cracks in the 3D tiles image and not in the glTF image. It also seems that the texture is a bit blurry in the 3D tiles version.
3D tiles (with cracks)
glTF (no cracks)
I would like to make use of 3D tiles rather than glTF as our models can get pretty large and we need to render them in a browser.
What would the cause be for the cracks and worse texture quality in the 3D tiles? Is there anything I can do my models to make it better?
