Autodesk Forge Viewer load multiple model

Question

I follow this article to create load assets function: https://forge.autodesk.com/blog/drag-and-drop-models-viewer

But i have problem about viewer performance, for few models it alright, but when i load many models, viewer rerender all time and not stable, video below (If i load all family in revit first then translate later, it works normal). I already set skipPropertyDb:true in options when load sub Model, all models are svf2. Are there any settings or solutions to keep it works? Something like clone model in scene or just load only geometry to viewer?

Answer 1

The viewer is optimized for rendering fewer models that are potentially very complex. If you go the other way around (rendering more models that are relatively simple), you'll miss out on many of the performance optimizations.

To work around this issue, you could try one of the following:

• include the additional models in the "main" model, and hide/show them (and move them around) as needed
• simplify the additional models you're inserting into the scene
