Problem with Baked GI

[Crono32]

Hey there developers.

I’ve been having an issue with global illumination ever since I upgraded my project to Unity 5. Right now on 5.1 I’m trying to set up a mix of baked shadow for static objects and real time for non static objects, when I hit build in the lighting panel, the following problem shows up, from a distance it seems that the bake is correct, but when I get closer or move the camera around the objects show a pretty ugly texture that darkens the objects.

See images for reference.

Any help on how to solve this would be much appreciated (I’m a noob to Unity’s new lighting system btw).

My guess is your bake isn’t working and that in the very last image I bet its using real time GI.

Something about changing the camera is exposing that the baked lighting is crap ; until its stationary and then calculates the realtime again (which it may not be doing when your moving or not till shortly after it stops moving?)

Are you using Mixed mode lights? They dont work at the moment - they wont cast shadows for dynamic objects.

Where did you get that from? Any official statement about it? In my case, mixed lights seem to work fine for dynamic objects (shadows are rendered without problems).

This was a while back, I havent used mixed lights since but since you asked but there are a lot of problems with dynamic objects casting shadows on dynamic objects, static objects and their are weird combinations that work and dont work .

They may have fixed some of it now but check these out:

(again read the developer input)

It depends on the render path too. Seems you might get something from forward with mixed lights.

Thx, Korno, now I see.

The links you’ve posted go far beyond what I am doing, so they’re certainly right. I’m probably just lucky in my case, at least speaking of dynamic shadows. Btw, I am using forward rendering, so that might explain something (though I don’t understand rendering paths in depth).

I’ve come across this thread here, because I am also having various problems with lightmapping and mixed/baked lights and Baked GI: e.g. blurry or extremely overcolored lightmap results, completely bright-lit objects when using lightprobes etc.

As I am not an expert, I’ve been thinking it was just my misunderstanding of the concepts (especially since the new lighting settings are now farer away than ever from being intuitive) But from what I understand here and from other similar threads, such problems seem to have been massing since Unity 5. So it’s probably not only me.
