    • Some combinations of shaders and rendering paths are not functional (see Prerequisites).
    • Bleeding albedo/emissive.
    • Library/GiCache is never purged, so might need to be cleared manually.
    • Scale In Lightmap equal 0 not fully respected (the instance should not get lightmaps, just influence the surroundings).
    • Emission from the Standard shader is only baked.
    • Skybox needs to use the RenderFX/Skybox shader and the textures used need to have Read/Write Enabled.
    • Emissive is clamped at 1.0f.

    How can we manually clear the Library/GICache?

    I'm using the default skybox. Do I need to use RenderFX/Skybox shader? How do I do that?

    That's intentional. For dynamic emission, you need to set mesh colour, not texture.

    Hi @121 That list of known issues looks very outdated (looks like early beta) and most of these are fixed in 5.0.0. Where did you find this?

    Library/GiCache is never purged, so might need to be cleared manually.
    - This cache directory is automatically trimmed, you don't have to worry about it.

    Thanks, I found that info in the 'GI Overview' docs on Sunday but it isn't there anymore.
