Has anyone noticed there web players appear more dark on windows. I’ve had people tell me that my games look dark on their windows, but on the mac they look bright. It’s not their monitor’s because I’ve had several people say the same thing. Any ideas?
For various reasons Mac OS X calibrates displays with brighter gamma than Windows does. I believe ColorSync Utility, in the Applications/Utilities folder, can adjust your gamma to one similar to Windows PCs if you want to test your games before deployment.
There isn’t an easy answer as to which gamma setting you should make your games for. Somewhere in between, I would suppose.
I would recommend authoring in PC gamma (and then test occasionally on Mac’s native) - on mac’s the game will look a bit whitened out. That’s still a lot better than having to go through all your light setups and make the lights brighter once you get test reports saying “I can’t see what’s going on”.
It is a well known old Mac issue. The usual practice for images is to change the gamma output from default 1 in Mac to 1,2 for displaying the same image in a standar PC screen. Same for video. But I just don´t knw how can we translate this to Untity, since I cannot find any options at all for this…

Make sure your monitor is calibrated to 2.2 or 2.4 gamma. I use 2.2, which is the mid-range of possible PC gammas. (Mac default is 1.8, which is oriented around print press work, but if you do digital media, web work, or even TV, then 2.2 is what you want). A great third party software calibrator is SuperCal, which gives me very good color fidelity.

Adjust your texture images in Photoshop or whatever to look good. If you use PhotoShop, use native PS files for your textures and use adjustment layers so you can make a quick change, save, and see how it looks in Unity.
-
REMOVE any ICC profiles on your textures. This means turning off color management in Photoshop. If you have a mixture of tagged and untagged texture files, they will import with different gammas and goof up the color matching.

In Unity, you can adjust the overall brightness (and overall color balance) of your scene in three major places:
A. The ambient lighting in the render settings. This sets how dark the shadows are.
B. The brightness of your actual light objects.
C. The base color of the material on each mesh.
Finally, depending on the quality of your monitor, you should check on real PCs with different monitors.
Thanks
good info doc - that should be on the wiki ; )
Great Steve. It’s really cool when people take the extra time to put things nicely into the Unify Wiki!
