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.

How can we import OBJ files into HoloLens project?

We want to develop a HoloLens app using our existing OBJ files, that allows users to select product from catalog and rotate and scale it.

Please advise how we can we use existing OBJ files.

  • you can import the OBJ fiels into unity project before build... or you can upload OBJ files to onedrive and load from there.

    I assume you meant OBJ and 3D Viewer? Not yet:

    If you don't mind trying beta apps you can see if the 480nm HoloViewer is what you are looking for as it supports OBJ files. It is free, and I would love to hear some feedback if anything is not working.

  • Thanks all. I'll just try out your suggestions and let you know..

  • Just tried the 480 nm Holoviewer app. Not bad, actually brought in an Obj file (but with no materials, only imports the obj), and previously, I had imported an FBX file. Movement, rotation, and sizing work, but are slow and with a delay of a few seconds after moving your hand/fingers. I like the materials, lighting, and color options. Enabling spatial mapping shows a mesh as if it was trying to map, but then the hologram disappears, and the mapping never seems to be complete. The holograms (in my case, a 3d model) do not seem to be locked into position very well, so when you move, they seem to move some also, so tough to walk around them and view from different angles. Is there any documentation for this app?

    msrAR1510 - Thank your for your feedback. I have copied your comments and my response to the project page:

  • I've been able to use Obj files and it's not much complicated. Simply imported Obj files in Unity3D and set up rigid body and collision.
