Support for Draco compression for 3D Models

Discussion created by adam3039 on Apr 26, 2020

I was curious if we can expect support for draco compression anytime soon within ArcGIS JS API 4.x. I noticed that it started being supported in ArcGIS Online & ArcGIS Pro, but as of 4.15 still seems to be unsupported. I get this console warning when trying to render a draco compressed GLTF:


[] gltf loader was not able to load unsupported feature. Required extensions: KHR_draco_mesh_compression


This would substantially reduce the browser memory we are using, and load times.
