Light turned Bright like with a higher Gamma or such

Hi,

I was working on the Tuscany Demo from OculusVR in Unity and after the scene appeared normally lit first, it at some point started to come accross overly bright.




I started to delete out parts of the scene to find the causing element, but none of the deletions actually changed the lighting back to normal.

I checked the color space to be "gamma", which so far is ok


Any hint how i can tackle this ?

If you turn all of the lights in the scene off does it go dark?

There are 2 possibilities that I can think of.

1. One of your lights' intensity is set wayyyyy too high. You should check all of your lights to see. Usually I use directional lights, and I've found that they work well with an intensity of 0.5 or so.

2. The ambient light in your scene is set wayyy too high. Check your ambient light settings in your scene settings.

 

I saw something similar with random web builds of a scene, related to the camera facing the sun (I could rotate the camera to trigger it on/off). Effected my sky and parts of the terrain (not trees), suddenly blown out like your ground and building.... My scene was Linear and Forward. After updating my webplayer plugin the same builds no longer do it....

 

the ambient light looks ok at 51 51 51



then when i delete all of the lights in the scene, it just stays that bright; same in play mode.


Regarding the plugin, not sure if i even have any. Googling it it says its a Unity Pro feature only.

 

By chance do you use a lightmap? If you do, turn it off and see if that changes anything.

In your scene view, at the very top, you'll see a little button that looks like a light/sun. Click that to turn it off and tell me if you're still getting light. If you are then it's most likely a shader problem I'd presume.

 

have ticked it off, but still



Yes, the scene uses lightmaps. The thing is that when i had opened the Tuscany Demo scene first, there the light was all ok, and it later suddenly turned bright. Basically the original scene, which i have not changed, is having the same problem since then as well.

 

By chance is Direct3D11 enabled in your player settings? It's uncommon, but I've heard of Direct3D11 having this type of bug on some machines.

 

ok thx! Dirct3D11 indeed was causing the issue !

 

No worries. Always glad to help.

 

Having the exact same issue, however the options have now changed in unity 5. I turned direct x from 11 to 9 (as that was the only option) and the terrain is super bright and all the otehr light mapped objects come wrong. Horrific with this new rendering tool.
