Great work, especially for a first jam! Really enjoyed the audio. It seemed like picking up the relic would often block the flashlight, not sure it that was intended to be an addition challenge to be picking it up and down frequently.
Also, I saw on the game page you linked a bug; I looked into it and there isn’t actually a bug (I left an in-depth explanation on the github page). I’ve used lots of subviewports on web and the only issues I’ve had is generally around getting myself confused local vs shared assets. I’ll try and load up your source later to see if it’s clear what’s wrong with web.
Again, great work and thanks for helping making everything better!
Update - I took a quick look, there’s more than one issue but, for starters, you need to know that the Forward+ render is only available on desktop (you can change it in the top right). Web can only run the Compatibility renderer and doesn’t support all the features that Forward+, critical to you, it does NOT support hint_normal_roughness_texture. Additionally the world env support is different.
If you want to export for web, generally the best thing is to change to Compatibility renderer so desktop looks just like web. Fortunately, there are warnings of unsupported features.
So, for starters, just comment out uniform sampler2D normal_texture : source_color, hint_normal_roughness_texture, filter_nearest; in both shaders (it’s not even being used). With that, the shaders compile. My guess is you’re utilizing some features on the world env that aren’t supported and I don’t know all the settings well enough to know if you can get the effect you want in other ways but hopefully this is enough to get you pointed in the right direction. At the very least you know it’s not a subviewport bug.
