MagicLord Hi there, With an emissive texture the GI probe baking works, but it doesn't work if the material is not using a texture but an emissive color. The green emissive object doesn't lighten the level, is this a bug ? This is how it should render
TwistedTwigleg Is use_in_baked_light checked in your mesh instance? By default it is unchecked, so that could be the reason it is not showing up.
