Hello,i have a question about b3dm. I can use draco in b3dm ,but i do not know how to using "_BATCHID" in draco? The draco GeometryAttribute only have POSITION / NORMAL / COLOR / TEX_COORD / GENERIC/ NAMED_ATTRIBUTES_COUNT attributes,so which one can be used in "_BATCHID"? Thank you!
The batchId is typically used for styling, see:
Are you trying to write a tool to generate 3D Tiles? You might find the samples here useful:
As well as this tools repo:
It might also be useful to try uploading your models on Cesium ion (https://cesium.com/ion) which will automatically Draco compress the result.
Thank you for your reply,It can work.
