Hi guys, I am looking to optimize my 3D scene and apply what i found in the documentation. but on the point with : freezeActiveMeshes i have issues. When i am applying this on my scene some meshes don’t display and sometimes juste disapear when my camera view just looks elsewhere. So i dont unde…

Thanks for the link, thats great to know. I solved my issue by adding : alwaysSelectAsActiveMesh = true on all my meshes. But now an other issue, my mirror dosent work anymore if i use freezeActiveMeshes before or even after the mirror creation. hum issues is endless :frowning: PS. “Active Mesh”…

Depending on what attributes are applied to your mesh, freezeActiveMeshes will not compute elements such as particle systems, decals, actions, and many other calculations. So depending on the materials and attributes of your mesh, it may not appear when you use freezeActiveMeshes. If you still have …

Technically freezeActiveMeshes will not evalaute the frustum clipping anymore and just keep the current list of visibile meshes. Maybe you can repro on the playground with your setup to see what is going wrong?

Hi, thx for replying. Hum i tried to create a PG, but the PG refuse to load the babylon file from my website :frowning: Is there a way to uplaod them with texture in the PG ? This is my code and a picture. [2019-05-08%2017_01_15-] var canvas = document.getElementById("canvas"); var engine = ne…

Here is a doc on how to reference external assets on PG: https://doc.babylonjs.com/resources/external_pg_assets

If you do not repro it in the PG I can only guess. This would be far more efficient with a repro activeMeshes are the list of meshes that the camera will render

I finllay have a PG for that but i cant figure out how to load texture :frowning: https://www.babylonjs-playground.com/#XYDFLV#1 Or you can see the result here : SM - 3D The mirror is in the bathroom straight ahead (actually with freezeActivaMeshes enabled) If I desactivate freezActiveMeshes, th…

I guess you need the alwaysSelectAsActiveMesh cause some of the meshes are first clipped so not in the active list so by doing so they appear in the list before freezing it :slight_smile:

i see, thats why it solved my issues, thx last thing to understand why mirror (reflection) dosent work :frowning:

Thanks to you alvov, is nice to answer it. Actually I stoped BJS to Unity, but it still good to know :slight_smile:
