Someone please tell me there is a fix to this ugly banding artifacts or whatever there called. The scene is being viewed in Baked mode. I’m calling them UNITY please stop doing this to us problems.
Im using 5.5.1p2. I only have 1 2048x2048 lightmap in this scene and the lightmap is uncompressed. Also here are my lightmap settings. I’ve tried using final gather at extremely large settings, nothing changed there. Tried so many things and settings nothing they never leave are always there. I can’t be the only one frustrated with this problem hopefully unity or someone has a hack or fix for this.
Seriously nobody has this problem? Unity lighting must be amazing then and I just don’t know what I’m doing. Atleast if someone from Unity would say hey we know about this and its fixed in so and so version would be great!!
You actually want compression off on the lightmap turning it on to be compressed looks twice as worse. Im not using any post fx or HDR just a directional light for lighting up the room for baked only lighting if you take a look at my settings. Im using the Forward renderer.
Also this is for Android not sure if that has anything to do with this problem in the lightmap. I don’t see why baking on PC standalone compared to baking in Android mode in the build settings would matter tho does it?
There’s actually nothing wrong with the lightmap, the Baked view mode in Unity is just screwed up and displaying the lightmap incorrectly. The darker colours are being stretched, while the brighter colours are being squeezed, probably because the lightmap is not being decoded correctly by the Baked view, which results in banding in the indirect lighting and brighter, blown-out colours in the direct lighting. I noticed the Baked view mode broke when Unity 5.5 was released, but it seems fixed in the 5.6 beta, so maybe duplicate the project and test it in 5.6. It’s annoying, because it makes viewing and adjusting lightmaps a bit of a hassle, but your lightmaps should be fine if you view them in Shaded view mode.
It still shows in the lightmap. I can zoom into the texture in PhotoShop and see the banding inside the actual lightmap texture. I’m making a level for gear vr with my samsung S6 and that banding still shows up like that. So its an Android build and I don’t have any texture compression on either for the lightmap or textures. With textures it helps lessen the banding but still very noticeable when in the gear walking up to the walls.
I’m using Legacy Shaders>Diffuse for all not using any mobile shaders at all or Standard shaders either. Changing it to default seems to half the banding not to bad but still noticeable. On dirty scenes with textures you dont notice this stuff its only clean scenes with solid colors is when you see this banding.
The Legacy Shader/Diffuse use same decoding as surface shader. So, this is not same bug in Mobile/Unlit (Support Lightmap).
Base on nindim’s bug finding.
If it’s en/decoding bug, your scene shouldn’t has any artifact if you switch to standalone platform or make standalone build. At very least, artifact should be less visible as lightmap with texture type default.
This is my guess, I suspect that indirect light calculation combining with en/decoding bug causing the banding. Try reduce indirect resolution.
So unity’s encoding for android lightmap textures is different then on pc standalone. That makes sense but we should get the option not be forced into this. I mean how can unity think that this looks good on mobile for baked lighting. Then again this is Enlighten which there trying to get away from for all baked lighting. Hopefully all this gets fixed with 5.6 with there new progressive lightmapper for all platforms that just want baked lighting. Sigh I feel like only thing I see unity guys saying now is either its a bug or it’s being worked on. Guess ill wait like everyone else see what happens with the new stuff.
Did you fix this problem, because i’m still having this problem in 5.6.0.f3 and 2017.1.1f. In the ‘pc platform’ everything looks great but when change to android the banding appears.
On Android, Unity 2017.2.0f3, seeing really ugly banding when using Baked Indirect. Switching to Subtractive lighting mode removes the artifacts completely.
If your platform is mobile it’s somewhat expected to get some banding, since lightmaps are encoded in dLDR (although there are changes for that in 2019.1).
If you have issues in a non mobile platform, start a new thread maybe, with some images of the banding and some settings, so we can suggest things.
