I am new to Cesium and 3dtiles, and got a problem with rendering my model.
In my work, I want to reuse some of my *.gltf files, so I use a *.i3dm file as a reference of a *.gltf file, and I provided the POSITION, NORMAL_UP, NORMAL_RIGHT and SCALE_NON_UNIFORM in the feature table.
Part of the *.i3dm files are rendered quite well, however some of them will disappear in some viewing angles.
I simplified my 3dtiles into a single tile, which has the abnormal appearence that I metioned. It is attached. (POSITION=0,0,0; NORMAL_UP=0,0,-1;NORMAL_RIGHT =0,-1,0;SCALE_NON_UNIFORM =0.001,0.001,0.001)
And the abnormal rendering actually disappears in some lower version of Cesium, such as v1.96.
I’ll preciate if you can spend some time to help me figure it out.
