Scan effect shader uses depth intersection to determine where to render the scan object's mesh. Physically move the objects further apart Simply increasing the distance between the fighting objects should fix z-fighting in most cases. However, transparent & text objects will generally not write to depth by default. I would like to know if it is possible to add custom shaders / Render states preview mode to the Unity Scene View Cause You may want to use a custom shader on "Scene View" for debugging. Since the subject is more relevant to image effects, this post won’t have the same format with the different code for vertex-fragment and surface shaders. These depth are calculated in real time and can be seen depending on how deep some object has went through snow. Far plane of only 20, and a "sky sphere" object that is 100000 in size. Remember that in “standard” fog equations we had only a single fog factor used to get our final color. I was able to get the shader to work by creating a new Unity project, importing the shader package, and importing the Kinect SDK package. If anything this book shows both the amazing work Unity has put in to action behind the scenes to help designers and developers create stunning effects in their games and the differences between what you may already know and what you need to know in order to make these effects yourself. although breaks a bit depending on camera rotation/position.
