Hello everyone.

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.

3D model scale and units


I'm trying to create a model in fbx format by constructing it in C++, using the FBX SDK. The model shows up fine in FBX Review, and also in the 3D Viewer app, except for the scale. I am not able to visualize the model in a 1:1 scale (real size). Are there any hints on how to do that? How are units interpreted by the app, and how should I construct my model such that it does not scale? Or can I prevent scaling in the 3D Viewer app?

[And does this also depend on the FBX SDK version?]



  • I've experienced 1000x scale sizes with fbx from blender. Which makes me believe that its an issue with their exporter. From Maya, they've been pretty consistent as long as you freeze the transforms. I'd love to hear if there are any remedies other than Applying a .0001 scale to the world matrix.
