I'm trying to add more than one color attachment to a render pass but it crashes.

[tofoz]

wondering if anyone can tell me what I'm doing wrong, I'm trying to add more than one color attachment to a render pass but it crashes with the error, "panicked at 'Handling wgpu errors as fatal by default'"
https://github.com/tofoz/bevy_custom_render is based off of the 3d/render_to_texture example.

What is the full output when you run with RUST_BACKTRACE=1?
