hi,
I just tested the setGammaRamp function...
it works, but when I close the app the gamma doesn't reset to normal !!!
OS: WindowsXP pro (sp2)

Works here (using the quake example). What did you test and what happened?

I used this short code snippet:

Code: Select all

#include <irrlicht.h>
using namespace irr;

int main(){
  IrrlichtDevice *device = createDevice(video::EDT_DIRECT3D9);

  device->setGammaRamp(2,2,2, 0,0);

  device->drop();
  return 0;
}

after running my desktop remains bright !!!
I'll have to run it again with device->setGammaRamp(1,1,1, 0,0); to get my desktop gamma back...

also with OpenGL driver...

Tested here too. And with the same results.

The Quake explorer,when it is closing, returns the gamma to 1.0,1.0,1.0. values.

Ok, that explains why I cannot see this in the examples

Guess we need a member in the device then to store the original value.
