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.

Object scale in Hololens not matching real world scale

Hi,

I have an object in our Hololens project based on a real world object. However, even though the scale is measured properly, when I place it as a hologram, it looks smaller than the real world object.

I've already tried recalibrating, but that didn't seem to fix the problem.

Does anyone know what's going on?

    Okay, so it turned out that the model wasn't the right size after all. Only by a barely a centimeter, but still enough to matter. Thanks for helping me out.

    Have you double checked the dimension size of your model in your model making software (i.e. Blender) to make sure it is the correct dimensions in there?

    Are you modifying the object in anyway through scripting? If it is an instance of a prefab check to make sure it is the same as the prefab in runtime to see if it is being modified.

  • Hi, the model itself is the right size. We do some modifications, but these are only related to position and rotation.

  • The only thing I know to tell you to do is to check it with a primitive shape. So I'd just take measurements (in meters) of something really simple like a filing cabinet or monitor or desk and then make a cube and give it a scale with the dimensions you calculated. Add a TapToPlace script to it from the HoloToolKit and move to where you can compare sizes. For me, the model is pretty spot on. So if you do this and your cube is off by the same amount then I'd look at filing a bug report but, if the cube looks the same size as the object you chose then its your model size that is wrong.
