While trying to deploy the existing downloaded project and set it up to a local hosting, getting this warning:
responseType: arraybuffer being served with Content-Type: application/glb
Trying to setup the correct MIME-TYPE and DEFLATE (gzip) settings using the .htaccess with these settings:
AddType application/wasm .wasm
AddType application/glb .glb
SetOutputFilter DEFLATE
ADD glb to deflate
AddOutputFilterByType DEFLATE application/glb
Compress HTML, CSS, JavaScript, Text, XML and fonts
AddOutputFilterByType DEFLATE application/javascript
I’m not too familiar with server setups but PlayCanvas servers serves GLBs as model/gltf-binary

Thanks yaustar, model/gltf-binary helped to solve warnings. Still trying to make mod_deflate to work, but that’s hosting issues )

Still trying to serve model/gltf-binary as gzipped with DEFLATE options ON.
We got the following response from the server support team:
Our senior team have taken a look at this on several occasions, and I’m afraid there isn’t much left to say - from our research, it looks like mod_deflate won’t target model/gltf-binary because it is binary data. In order to deliver compressed files in that format, you should use a command before deployment, as explained here:
gltf-pipeline/README.md at 73a8dbc9e8987077396eb314c92bc22d83c692d4 · CesiumGS/gltf-pipeline · GitHub
The above would also be much quicker than on-demand gzip, so it’d be more beneficial to use this.
Does this makes sense to try ?

This is preview URL on the hosting platform: http://gallery.familyforeverychild.org/PreviewOnly/ as you can see the response for *.glb files is empty with net::ERR_CONTENT_DECODING_FAILED
Here is the working example: https://playcanv.as/p/Dw7QSLcJ/
I can’t see the warnings/errors on console. All the GLBs are loading correctly for me:
Not sure which command they are referring to tbh. At the moment, the PlayCanvas export doesn’t support Draco compression yet and that does require a separate WASM library so I wouldn’t go down that route yet unless you really need it if that’s what they are referring to.

Thanks for your quick reply.
<IfModule mod_headers.c>
<FilesMatch "(\.glb)$">
Serve correct encoding type.
Header append Content-Encoding gzip
Header append Vary Accept-Encoding
</FilesMatch>
</IfModule>
We just reproduced everything on our local Apache server and managed to serve model/gltf-binary with gzip.
All we have to do is uncomment/load these two modules inside httpd.conf:
LoadModule deflate_module modules/mod_deflate.so
LoadModule filter_module modules/mod_filter.so
And add the .htaccess to the project with following options:
<IfModule mod_mime.c>
AddType application/wasm .wasm
AddType model/gltf-binary .glb
</IfModule>
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/javascript model/gltf-binary
Everything works on our local server as expected.
Thanks for sharing! (we REALLY ought to have a page for Apache, AWS hosting in documentation
Just to confirm that you are all good to go now?

Finally we managed to solve the issue with gzip on the shared hosting (20i). It was a nightmare for two weeks till they finally made something there and it starts working as expected.
http://gallery.familyforeverychild.org/
.htaccess file now looks like this:
AddType application/wasm .wasm
AddType model/gltf-binary .glb
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/javascript model/gltf-binary
