[OSX] Intel HD 4000 - Shader issues

Unity Engine
1

Hi all,

My mac hard-drive was full, so I decided to dump Windows to free some space and return to OSX for development.

Everything went well, except that most of the shaders I use now display artefacts on screen. What’s weird is that the spots that appear on my mesh surfaces take the color of the camera background…

PBL shaders made in Shader Forge:

Blackfire studio Winter Shaders:

I was wondering if anyone ever encountered the issue and if yes, is there any way to avoid it?

The same chip, which is an Intel HD 4000, worked well in Windows 8.1, so I don’t understand why it would be broken under OSX.

EDIT: Ok it seems to be a problem with Deffered Lighting on that particular chip. Really weird that it does not happen on Windows. Anyway, I’ll use forward for now.

Mac OSX and Windows use different graphics drivers, so this is more likely to be a graphics driver bug rather than your HD4000 deciding to play up after you dumped Windows.
