	//World effects
	//#define DEPTH_OF_FIELD 		// Enables Depth Of Field   # Blurs objects in the distance
	#define PARALLAX_OCCLUSION	// Enables Parallax Occlusion Mapping  # Makes surfaces look bumpy and 3d at the cost of fps. Worth it
	#define SSAO			// Enables Screen Space Ambient Occlusion  # Looks good if you are stuck on Object Dynamic Lighting
	#define SUN_SHAFTS		// Enables Sun Shafts (god rays) # Only noticable on Full Dynamic Lighting, looks very nice but causes poor performance on some computers. Also makes the environment much brighter and natural.
	#define USE_SJITTER		// Uses shadow jittering, a modern method of smoothing out shadow edges. Applies to flashlight, and to world if SUN_FILTER is enabled.
	#define USE_SUNMASK		// Enables sun shadow masking # Seems to be the line that produces shadows based on sun orientation. I am not sure if F32 needs or it should avoid it

	//Screen Space effects
	#define USE_MBLUR		// Enables Motion Blur # This forces Motion Blur on like -mblur. Adjust the blur amount with MBLUR_COEF later in this script.
	#define IMPROVED_MBLUR		// Use distance-depending Motion Blur - Adjust START_DIST and FINAL_DIST to your needs.
	//#define SKY4CE_MBLUR 		// # Seems to break Motion Blur and Anti-Aliasing altogether
	#define SATURATION_FILTER	// Enables Saturation Filter, giving a grey like appearance to areas which are "unsafe".
	#define CONTRAST_FILTER		// Enables Contrast Filter, giving a grey like appearance to areas which are "unsafe".


	//Other
	//#define USE_F32		// Enables Float32 mod. Breaks saturation and contrast filters. # If you are using Panoramic Mod 2.1 FINAL from Argus make sure you have a // at the start of this line
	//#define USE_F32_FOG		// Enables Float32 style fog. Requires Float32 to be enabled.
	#define CUSTOM_SHADOW_RESOLUTION int(2048) // Use a custom shadow size. Default is 1024 (1024x1024).

//Depth Of Field

	//Basic options:
	#define DOF_QUALITY int(12)	//Amount of DOF samples. Maximum value is 12.

	//Distance Options:
	#define MINDIST float(15.0)	// Minimum distance DOF starts. Default is 0.4.  // TWILIGHT KET USES 15
	#define MAXDIST float(275)	// Distance at which DOF stops rendering. Default is 375
	#define MAXCOF	float(4.0)	// Blur amount - if using DDOF, this should not differ too much from DDOF_MAXCOF (I use same value)

	// Meltac: Total DOF Extensions
	//
	// Blur methods - enable at least one; can be combined/applied together,
	// however in my experience the overall effect was worse in combination;
	// use r2_aa_kernel to adjust the mix, 0.3 = full classic; 0.7 = full gaussian
	#define DOF_CLASSIC			// Use classic blur algorithm, as implemented by Sky4Ace
	#define DOF_GAUSSIAN			// Use simple gaussian blur algorithm (blurs stronger with same MAXCOF value)
	#define DOF_CORRECTION float (6.0)	// Factor to equalize the amount of gaussian to classic blur. Don't change this unless you know what you're doing.

	// Oversampling for better quality (not really improving much, but making game startup slower - use at your own risk)
	#define DOF_OVERSAMPLING int(1)		// oversampling ratio. Default is 1.

	// Near Field DOF (see also Dynamic DOF, because the effects are interfering!)
	#define MAXNEAR float(0.7)		// Distance at which Near Field DOF starts. Default is 0.7. Larger values will blur your weapon more, and not only its near part.
	#define MINNEAR float(0.0)		// Distance at which Near Field DOF stops. Default is 0.0
	#define MAXCOF_NEAR float(15.0)		// Near Field blur amount. Interferes heavily with DDOF. Default is value 7.0 without, 15.0 with DDOF.

	// Zoom DOF
	#define ZOOM_MINDIST float(15.0)	// Minimum distance (radius) from screen center where DOF starts.
	#define ZOOM_MAXDIST float(260.0)	// Distance radius from screen center at which DOF stops rendering (beyond that value - full blur).
	#define ZOOM_MAXCOF float(80.0)		// Blur amount at the screen border while zooming.
	#define ZOOM_FACTOR float(10.0)		// The stepness of the blur amount raising from center to border. Good values are 10-12.
	#define ZOOM_BARRIER float (20.0)	// (DEBUG) Distance from the screen center at which blurring starts, in relative pixels.

	// Dynamic DOF
	//#define DDOF				// Enable/disable Dynamic DOF (blurring coefficient is MAXCOF)
	#define DDOF_MINDIST_ADD float(0.7)	// Added to view distance, at this distance begins blurring
	#define DDOF_MAXDIST_FACTOR float(4.0)	// Mindist times factor = maxdist
	#define DDOF_MINDIST float(0.0)		// Minimum distance DDOF starts.
	#define DDOF_MAXDIST float(10.0)	// Distance at which DOF stops rendering. Beyond this view distance, only minor DDOF
	#define DDOF_MAXCOF float(4.0)		// DDOF blur factor - good balanced is value 2.0 - 5.0 - see also MAXCOF
