--resolution option isn't having an effect

[bravokiloecho]

When I run the command:

npx gltfjsx package-30.glb --transform

it compresses the model from 28.1MB to 866KB. But when I try any different value with the --resolution prop like this:

npx gltfjsx package-30.glb --transform --resolution=256

(or replace 256 with any other number) it still compresses down to 866KB.

So I'm not sure the --resolution prop is having an effect. Am I using it correctly here?

Thank you (and thanks for such an amazing tool)!

If I use --resolution [value] or --resolution=[value] it works. Maybe you can share your model.

Hello! I can't share the model sadly. Are you using the --resolution flag with the --transform flag?

Could you check the output of the Texture tables with —

npm install --global @gltf-transform/cli@next

gltf-transform inspect package-30.glb

That would tell you what the texture resolutions are in the output.

Thanks for the tip @donmccurdy!

When I run either

npx gltfjsx package-30.glb --transform --resolution=256

or

npx gltfjsx package-30.glb --transform

and inspect the model, the results are the same (texture size of 1024x1024):

Another update...

When I cloned this repo and ran it locally, the --resolution option worked as expected
