We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.
The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.
The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.
On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.
So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.
Loading a big 3D model at runtime
As a part of my research project, I need to download the 3D model from my web server, which is output of a photogrammetry software, so these models are huge(as big as 1.4 million vertices in the mesh). After downloading the model, I am not able to render it at runtime due to number of vertices in it as Unity does not load anything more than 65536 vertices for a mesh.
However, when I try to render the same model in Unity Editor, Unity is making 22 groups of the model(with 65532 vertices in each) and then it loads smoothly without any problem on HoloLens.
So only option(unless I am missing something) is to break the model into multiple groups of vertices not more than 65536 each, before saving it onto server.
Can you recommend or point me into direction of achieving this?
