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.
The problem about HoloLens crashes when importing FBX model
I encountered a strange problem when I was developing a software based on HoloLens environment.
I built a project on Unity and imported the Mixed Reality Toolkit (MRTK) package. According to the instructions of the official website, I exported the FBX model from City Engine to HoloLens, and the Unity console didn't prompt any errors.
Then the problem is coming, the HoloLens System terminated when I used VS 2017 to debug the proposed program in Hololens, and the interface of HoloLens displayed the following information: "trying to map your surrounding" (Figure 1).
However, I noticed that the Unity console didn't show any errors when HoloLens crashed. So I did the following tests to solve this problem:
1 Based on this project, I removed all the scripts and other models, leaving only the model and the scenes (camera, cursor, input module) configured by MRTK. It does not work.
2 Based on this project, I replaced FBX model with the sample CUBE model, and the other remains unchanged. There was no such problem occurred when I posted the revised project to HoloLens.
3 Finally, I tried to remove the MRTK package, leaving only the FBX model and compiling the release model to the Windows platform. The program is running normally and no error is reported.
The size of FBX model is about 27 MB (Figure 2):
The Unity Editor version is 2017.2.1f1
The Mixed Reality Toolkit Release version is 2017.2.1.4
Are these problems are caused by the incompatibility between HoleLens and FBX model?
How can I solve this problem?
