Hi everyone. I am having some issues trying physics for the first time. I have looked at the simple examples of physics in the Deep Dive as well as a few from this forum (example: Babylon.js Playground ). You can see the soldier falling through the floor here: [sc] The section of code that loads …

Hi @Cedric and @sebavan … Okay I got it. My answer was in this post: How to (correctly) import gltf and add physics - #2 by PirateJC I used the following lines to make the physics show up: let soldier = result.meshes[0]; this.soldier = soldier.getChildMeshes()[0]; this.soldier.setParent(null); s…

Okay I have made some progress. My guess is that maybe I can’t just attach a physicsImpostor to the red-highlighted floor node that is baked into the model? (Plane001). I added a cube to see if that would fall through the floor like the soldier (it did). So I have added a ground mesh with MeshBui…

Hi @swim81 do you repro in a playground? it’s easier for us to debug with a small scene. Usually, meshes/impostors that fall thru ground are already below (or a portion of it) the ground. Did you check with the physics debugger? Can you test to spawn the character higher?

Hi Cedric! Yep I set the character’s Y to be up pretty high… so when the scene loads it drops down a ways before passing through the floor. Is there a physics debugger? You actually just answered one of my questions :slight_smile: I think this must be the link? The Inspector | Babylon.js Documentat…

Hmmm shoot. I haven’t been using the playground… and I can’t seem to get the inspector to run locally (I’m using plain JS with webpack and modules, Flask on the back-end to serve the build and models). ERROR in ./node_modules/@babylonjs/serializers/glTF/2.0/glTFMaterialExporter.js 9:0-62 Module n…

I guess your version are different between core / serializer and inspector. Can you check in your package.json ?

Hi @sebavan sure thanks! "dependencies": { "@babylonjs/core": "^5.30.0", "@babylonjs/loaders": "^5.30.0", "@babylonjs/materials": "^5.30.0", "ammo.js": "github:kripken/ammo.js" }, "devDependencies": { "eslint": "^8.26.0", "eslint-config-airbnb-base": "^15.0.0", "es…

Can you look into your node_modules folder for which version is installed as I am thinking the caret might have force a more recent minor version of one of the package ?

Oh sure… sorry I realized I had uninstalled the inspector. I just reinstalled and it shows this in my package.json: "@babylonjs/inspector": "^5.35.1", And here are just the top portions of each package.json in the libs that you mentioned: $ cat node_modules/\@babylonjs/serializers/package.json {…

core is not on the same version can you move it up to 35.1 as well ?

Yeah. This line should become a must have in the doc as it generates just so many different issues:
