Shader for coloring units and terrains does fail on web export

[HunterNN]

I have encountered an issue where the shader used for coloring units and terrains is not working as expected when exporting the project to a web format. I tested it in Firefox and Chromium:

As you can see, the units and buildings are all in their respective sprite colors.

Deleted previous export templates and redownloaded with Official Github instead of Best Available - and exported in Compatibility - now the shaders are working. Tested in Firefox and Edge and using Itch.Io with BufferArray support. (Won't catch me installing Chrome)

Based on what I can see, it seems that the problem lies in the cache generation process for the .godot folder. Specifically, the shader issue only occurs when this folder is missing, and it gets created using this command
https://github.com/Codename-Recon/Codename-Recon/blob/df383d65bc19214a40b0d4bae97aad8647c6cfc3/.github/workflows/client-exports.yaml#L90

It seems that this step may not be necessary at all, as none of the example repositories use such a line or commit the '.godot' folder. I suspect that the --export-release flag should generate it automatically, but for some reason, it doesn't:

abarichello/godot-ci#127

An export to the web using a normally generated '.godot' folder has no issues with color shading.

@Dracks also FYI

Could you please test the multiplayer feature for me if you have hosted it on Itch.io? To do this, simply click "multiplayer" and then "lobby" from the main menu. When hosting on a local computer, it appears to be unable to connect to Nakama.

Same result on Itch.io, cannot connect to the lobby server

Ok back to topic.

While it's great that we can manually export to the web and have the shader working, we still need an automated solution for this issue #25 . Therefore, I will keep this issue open for now.

I have posted a comment on the following issue on the godot-ci repository regarding this matter: abarichello/godot-ci#127 (comment)

I have tested it further and found that the problem lies more with the shader parameters than the shader itself. I have created an issue on the Godot GitHub repository to report this problem:
godotengine/godot#88033

Godot 4.3 will fix this issue. It is already solved in Godot 4.3 dev 4 (tested with minimal reproduction project).
