Hi ， i got a STL file , and the attachment is how it looks like in threejs. but i got a problem, convert the stl to drc by draco_encoder. the model become very bad. see attachement below.
project (1).json

i believe the issue is about the model'size, but could you provide some methods to process such model files?

just let me know if you will fix this issue.
Thank you very much!
