Models get too bright on Android devices after upgraded to Unity 3.5

After we upgrade our game to 3.5, some game characters get over bright (some do not) when deployed on Android phones (tested on Sony Ericsson Xperia). These characters look normal in the editor though.

The first picture is in the unity editor and the second is on Android phones.

This did not happen with earlier versions of Unity.

We did a few experiments:

  1. we take away the material of the model and tested on the Android phones, it was still too bright;
  2. we take away the light in the environment, the characters were as dark as the rest of environmental objects. But even with very dim light (intensity=.05 directional light), the characters start to glow, as bright as they did in the normal lighting (intensity=.2 directional light)
  3. we take away the skeleton of the character, it stops glowing. But as soon as we put any skeleton, even with just one bone in it, it start glowing again
  • we did not use self-illuminated shader
  • when exporting the models, no lights were included

We pretty much run out of ideas . Anybody encounter similar problems? How can we solve this problem?

Thank you very much!

That’s something you should report to the support. This is a user forum, where users help other users and the Unity Staff rarely looks here.

Use the Help Menu > Report a bug feature to report it to Unity support

Hello!
I noticed this too…

Thanks Tseng! We will report the bug.

Where? Neither the updater nor the website points that there is a 3.5.1

didn’t jochiam say something about a bug in the past where baked lights also cast light so if you doubled your lights in 3.4 to get realtime lighting you might have extra lights that are being used now.

also, where is 3.5.1?

Hi!

Sent the bug report and hopefully they will fix the bug soon.

Thank you Nicoletta for sharing that you encountered the same problem.

3.5.1 is beta. You’re not suppose to discuss beta releases in this forum (except for public previews).

I’m seeing the same thing on the iOS, but doesn’t seem to be affecting all materials.

I’m only seeing it on my background material, the shader is Transparent/VertexLit. See attached images for difference between 3.5 and 3.X (3.0? 3.2? I’m not sure). The last one is 3.5.

Don’t know why this is the only material affected, but it is the only one I’m changing the mainTextureOffset and Scale via code.

Sorry I did not know the rules of not talking about the beta on the forum. I deleted my comments about it. Thanks technicat for pointing this out!

Update: we changed the project setting to be OpenGL ES 2.0 (1.x) and the models as shown in the pictures stops glowing. But some other models get dark. Still trying to figure things out.

Hi madagascar, today…really…since today i have the same problem, the build yesterday and the other days and weeks before works good. It is a very strange. Now i help me with the player model, i reduce the texture from white to lower dark, then it is ok. But i hope they find this problem. When i take 2.0 the player is ok, but yes…other models are very dark. And it is strange too, when i play this game on my Android HTC Sensation XE, then the diamonds in the game change the light, when i have collect 1 diamond or 2, the other diamonds goes from dark to normal.
I send the problem to Unity3D and yes…i hope they find this problem fast.
