How To Start
The effects could be applied only in a camera view.
In order to apply effects, you have to create a post process user object which contains all properties. You can do that from Assets Browser or from the Post Process Tool. In Assets Browser the user object is located in Assets / Templates / Shading Elements
Here you can active the desired effects and the whole effect system in order to see the result in real-time in the viewport.
Supported drag'n'drop operations
if you drag camera / light / null, they will connected into Data Camera / Lens Flare Light / DOF Focus Object
if you drag one post process user object into another, the values from on object will be copied into another one
if Camera is assigned in a correspondent property of a post process object, then post processing effect become a local, just for a specified camera
Post procesing effect applies only on user camera and skip any system camera and Perspective as well
Better to not combine Camera Effects (Antialiasing, Depth Of Field) with post processing effects
For Antialiasing better to use render option. BUT the option conflicts with Reflection shader, so you will not see reflections!
Default Configuration
Default values for the properties are stored in My Documents \ MB \ 20xx-x64 \ config
Name of a configuration file is < PC Name >.PostProcessing.txt
Python tool to tweak post effects properties.
Effects Common Notes
DOF and SSAO and any other effect which is using depth buffer could be sensible to camera near/far planes
GLSL Shader stores value in single float, so please take care about too big values for the far plane
DOF
In DOF Effect you can manually specify a focal distance.
If Null is assigned in the Focus Object Property, Focal distance will be computed automatically.
When Use Camera DOF Properties is on, then Focal Distance and Focal Range will be taken from Camera Real-Time effects
To increase a quality of DOF, try to insrease values for Samples and Rings
Lens Flare
PosX and PosY are percent of screen size (width and height)
Post Effects and HUD
The post effects modify the final image, where HUD elements are draw as part of it. In order to recover original HUD, the post process plugin has special feature to emulate the HUD drawing on top of post processed image. That is not a full 100% replication of MotionBuilder HUD system, but it covers most of needs with printing out text, rectangles.
Additional features of the plugin
stream view image via UDP socket (used for virtual camera communication), was designed for a Google Tango tablet - Introduction To Virtual Camera
trigger evaluation of Python Script devices during rendering. That feature is always enabled and it helps to trigger Embedded Python Scripts while running an offline rendering.
