Thanks Omar for the method, but the owner of the data is a local government and they don’t want to upload real city data to the different countries’s server. This is a problem I have. I’m trying to solve this situation using FME or another 3DTiles converter. FME is really user friendly and easy to convert any geospatial data to many different format. But I guess 3DTiles converter has a little problem with material or color options…
I’m also trying to solve this problem in Cesium to reset any color or material settings. But I couldn’t do that for now. .I’ve tried many codes. If it is possible, I have to change the material settings of the polygons…
