Texture gamma

Is there a way to change the gamma value of texture by script?

    // Get the image manager
    var oImageMgr = App.getImageMgr();
    // Define the desired gamma
    var nGamma = 2.2;
    // Get or create a DzTexture for the image; set gamma if created
    var oTexture = oImageMgr.getImage( "Absolute/path/to/image.ext", nGamma );
    // If we have a texture and its gamma is not the gamma we want
    if( oTexture && oTexture.getGamma() != nGamma ){
     // Set its gamma to the desired value
     oTexture.setGamma( nGamma );
    }

    Thank you very much. :D

    Is there a way to check a particular node for diffuse textures that aren't at 2.2?  This is probably a basic question but I'll ask since I'm new to Daz Scripting.  

  • Once you have the map oTexture.getGamma() will get the gamma. For getting the maps, see http://www.daz3d.com/forums/discussion/57229/

    But how do you know which channel to set the gamma value? If you want only the Base Color? Or if you want only the Translucency Color?

     

    Thnx Rob

    You'd get the image from the property, then use Rob's code to get its gamma.
