Oil Paint

Oil Paint is a post-processing effect that can turn your game into a piece of art. It is based on Anisotropic Kuwahara filter.

Inside the Editor.

Once installed, select the camera of the scene and add the component ‘Oil Paint‘.

 

 

 

When you add it you will see something like:

 

 

In the first zone (1) you can change the strength of the effect. You can also change ‘Mode‘ between ‘Screen, ‘Layer’, ‘Dual layer and ‘Distance. Later we will see how they work. You can also control the intensity of the effect by selecting between ‘Low‘, ‘Normal‘ or ‘High‘. If you want to manually adjust the intensity, select ‘Custom‘.

 

Values above six may impact the performance.

 

The ‘Color’ (2)  area is used to modify color parameters and you must activate it (in the small circle near the label) to be able to use it. In ‘Advanced settingsyou can adjust the ‘Depth threshold‘ parameter to adjust the sensitivity in the layers mode, and the ‘Unroll loops‘ parameter to unroll the internal loops of some shaders.

 

Pressing at ‘[doc]’ will go to the online help and in the ‘Reset ALL‘ button some parameters will return to their default values.

 

I said that there are four different modes. The first one is ‘Screen‘ and is the one used by default. It makes the effect apply to the whole screen. Another mode is ‘Layer‘ and with it you can apply the effect only to the layers you want.

 

With ‘Dual Layer‘ you can also set another intensity for the zones that are not affected by the selected layer. This can be useful if you want some objects to have better definition than others. When this mode is selected, the intensity is automatically set to ‘Custom‘ (1 the selected layer, 2 the rest).

 

 

 

With ‘Distance‘ mode you can select the depth curve to modulate the effects strength. The range starts at the ‘Near‘ distance of the camera and ends at ‘Far‘.

 

 

If you see any accuracy faults, you can adjust the sensitivity with ‘Depth threshold‘ at ‘Advanced settings. Also ‘Layer‘, ‘Dual Layer‘ and ‘Distance‘, add a depth texture to the camera, and may not be available on some mobile platforms. You should also keep in mind that both modes depend on the ‘Far‘ parameter of your camera. If you use a ‘Far‘ too large (default is 1000), you may have precision problems, so I advise you to reduce it as much as possible.

 

By code.

All code is inside the namespace ‘Ibuprogames.OilPaintAsset‘ and the main component is ‘OilPaint‘. So if you want to use it you must first import its namespace:

 


using Ibuprogames.OilPaintAsset; 

 

If ‘myCamera‘ is a valid camera and you want to add the effect, you should do something like:


OilPaint oilPaint = mycamera.gameObject.AddComponen<OilPaint>();

 

All the code are well commented, I recommend reading the code if you want more information.
