I need a smoother experience in MetaQuest 3

1

Greetings from Shapespark’s colleagues.

I recently received a commission to take a tour that could be enjoyed from the Meta Quest 3. The work is medium-sized but it carries many elements, I’ve tried to clean geometries and minimize textures since sketchup and then in shapespark.

However, when you see the virtual tour with the meta Quest 3 the experience is not fluid, when you see the areas with the most polygons the image begins to stick or jump resulting in an experience that can make you dizzy.

  1. What can I do to avoid that?
  2. Should I keep going down polygons and textures?
  3. What are the optimal data so that a model can be seen smoothly in the meta quest 3?
  4. Are they the same as for cell phones?
  5. Can I connect the metaquest 3 by cable to my PC and use the power of the PC instead of the glasses?
  6. Does anyone have any experience about it that they can share?

(I’m sorry, I can’t share the model for a confidentiality agreement, but you know what I’m facing!) Greetings from Shapespark’s colleagues.

Update: I’ve already managed to reduce polygons and objects, but materials are still the same, what can I do to reduce materials?

Primarily, you should reduce the number of triangles in the scene. For Quest 3 in stand-alone mode, it’d be best to keep the number of triangles below 1.5-2M. How many triangles do you currently have?

Shapespark materials are based on SketchUp materials, so to reduce the number of materials in the Shapespark scene, you need to reduce the number of materials in SketchUp. If you find that some SketchUp material is duplicated, the Material Replacer extension allows you to replace all the duplicate material uses with the primary material. Then, you will be able to remove no-longer used duplicate material.

Yes, it’s possible to connect Quest to a PC using the Meta Quest Link/Air Link and leverage your PC’s GPU for rendering. Here are the steps.

  1. Connect Quest to your PC with a high quality USB cable. The Link sends a substantial amount of data, so not every cable has enough data bandwidth. Alternatively, you can use Air Link, if you have a high-speed WiFi network.

  2. Install Meta Quest Link https://www.meta.com/en-gb/help/quest/articles/headsets-and-accessories/oculus-link/connect-with-air-link/

  3. Open Meta Quest Link and make sure that “Unknown sources” are allowed (applications from outside the Meta Store like Google Chrome) and that Meta Quest Link is the default “OpenXR runtime”

  4. Open Chrome.

  5. Open a simple VR demo, for example: https://immersive-web.github.io/webxr-samples/immersive-vr-session.html, to check if the VR through the Link works properly

  6. Open a Shapespark scene and switch to VR mode click the VR button in the bottom right corner after the scene has been loaded, the same way as with Quest in the stand-alone mode.

hello @wojtek , send you a private message with the link so you can analyze the scene and give me your advice, did you receive it?
