1. A concise explanation of the problem you’re experiencing.
Hello evertone, I’m beginner of cesium. i have some city building models with format in kmz.
And i had used the collada2gltf to change my building model format into .gltf, but this
wired that it has strange black shadow on building surface and whole building looks so
dark. you can see them in following screenshot about the presenation in cesium and google earth.
2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.
My code used to load my model is following:
var modelMatrix1 = Cesium.Transforms.eastNorthUpToFixedFrame(
Cesium.Cartesian3.fromDegrees(120.300028781098, 22.6224908296288, 20));
var model1 = scene.primitives.add(Cesium.Model.fromGltf({
url: ‘r51/P2_land2271_24.gltf’,
modelMatrix: modelMatrix1,
scale: 1.0
}));
3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
I’m wondering about what may cause this black shadow and how to fix this and how to make my model brighten
