|  norlock joined the room. | 18:45:27 |
| norlock | Does anyone know here what to do if you import something from blender that looks huge in wgpu? It "seems" ok with my limited knowledge in blender | 18:46:17 |
| norlock | scale in blender is 1x1x1 | 18:47:15 |
| David Huculak | Do u have a repo that produces the issue? I could take a look | 19:04:59 |
| David Huculak | Could be caused by a number of different things | 19:05:25 |
| David Huculak | My first guess would be that the object you're comparing it to is actually really small | 19:05:54 |
| norlock | Ah ok | 19:14:43 |
| norlock | yes | 19:14:45 |
| norlock | I commit it here: https://github.com/Norlock/sparticles/tree/models. | 19:16:20 |
| norlock | On gltf viewer it seems fine: https://gltf-viewer.donmccurdy.com/ | 19:16:56 |

| David Huculak | it looks like your gltf loader isn't taking into account the transforms from the gltf nodes | 21:18:22 |
| David Huculak | and the drone.glb model you're loading has a scale of 0.01 applied to it on one of the nodes | 21:19:57 |

| norlock | Ok I will have to look where I can find that, because the gltf-loader doesn't support that function | 21:26:43 |
| norlock | https://docs.rs/gltf/latest/gltf/struct.Primitive.html | 21:27:14 |
| norlock | or is it morph targets? | 21:27:40 |

| David Huculak | you'll want to call this transform() function on the nodes that you're loading as well as recursively multiply them with their parents to get the correct global transform | 21:33:35 |

| norlock | Ahhh thanks | 21:35:03 |
| David Huculak | this small pdf cheatsheet helped me out a lot when writing a gltf loader for my project: https://www.khronos.org/files/gltf20-reference-guide.pdf | 21:36:10 |
| norlock | Yeah I just extracted the JSON from the GLB now which I could have done before as well :/. Cool I already had some other weird issues with other models | 21:37:39 |
| David Huculak | if you convert your .glb to a .gltf there's a really nice vscode extension that makes it much easier to explore those json files + preview in vscode directly | 21:40:03 |

| norlock | I don't use vscode but maybe I can find some alternative for neovim / online | 21:45:32 |
