Loading and Unloading Specific Model Nodes Using onDemand Streaming

My reply to a previous post also applies to your situation:

How to Load a Specific Part of a Model Instead of the Full Model in SCZ/SCS?

Hello @shubham.suryawanshi, You have a couple of options in terms of having more control on what is loaded in the viewer. The server allows for different streaming modes. Most relevant to your situation is OnDemand. There is an example available as part of the quickstart module. To view this example, please do the following: Launch the server by double-clicking HOOPS_Communicator_2025.X.0\quick_start\start_server.bat View the example in the Web Viewer by clicking this URL: http://localho…

In the same thread I replied to, the original poster had success using a manually shattered workflow which I recommend to you as well:

How to Load a Specific Part of a Model Instead of the Full Model in SCZ/SCS?

I went with the second approach — using shattered Stream Cache sub-assemblies along with the loadSubtreeFromSCSFile() functions. To do this, I used this GitHub repo: GitHub - toshi-bata/shattered: This sample creates shattered assembly from a monolithic assembly file using HOOPS Exchange and LibConverter of HOOPS Communicator. This allowed me to split the model into .scs and .png files and load them on demand. However: Drawback: The shattering process is quite time-consuming, even fo…
