[Nickan]

The error disappears when I set the "always_blue = false" on line 99

[CleanCut]

Confirmed. I can also reproduce this on macOS for both v0.3.0 and master, including the workaround described in the previous comment.

Same here. The fix here https://github.com/cart/glsl-to-spirv/pull/4 by @goodbadwolf resolved it for me. Looks like we need to push out a patch release :)

0.2.1 of bevy-glsl-to-spirv is published. This issue is resolved for the latest bevy crates.io release by deleting cargo.lock or running cargo upgrade.
