URDF Visualization in VR #13

Open hu-po opened 2 months ago

hu-po commented 2 months ago

Thanks for the great repo! I am running into issues when trying to visualize a URDF file in a VR headset. I can run the mars rover example fine and see it in the headset with textures/materials. My URDF file also works fine on the browser (though it has the white default material even though material is defined in the urdf). When I try my URDF file on the VR headset (QuestPro via ngrok) I cannot see anything (meshes or textures). I have tried various formats (obj, gltf, glb) and different materials, but still no luck. Any ideas around what might be happening? Or how I could set a default material of some sort for the URDF?

Hello Hugo,

Thanks for your interest! For URDF files that I have in my hands - they work in both the VR headset and the browser. I don't know if it is possible, but if you could share the URDF file that reproduces this issue, it would help locate the issue.

Thanks so much for the help. Here is the URDF file I am using, it uses .obj files. It has materials defined in the .urdf file, but I have tried removing them and also converting the files to .glb, .gltf, and .stl with no luck.

I saw you are using the three.js urdf loader that I also used in a previous project. In that previous project I had to manually set the material color for the object3d, I saw you are doing something similar in vuer-ts but I don't know enough about three.js to have a good intuition around what could be going wrong.

Anyways, hope that gives you more context. Thanks again for the help and for providing this awesome library to the community.
