Where to get the post-processing stack + latest news
The post-processing stack is a key toolset for artists working in Unity. We continue to optimize it for all platforms, including VR. Here are some of the latest updates and news for your inspiration.
The stack in brief, and where to get it
The post-processing stack is an über effect that combines a complete set of image effects into a single post-process pipeline. This gives you advantages such as:
- Effects are always configured in the correct order
- It allows combination of many effects into a single pass
- It features an asset-based configuration system for easy preset management
- All effects are grouped together in the UI for a better user experience
The stack is available for free on the Asset Store here. After you get it, make sure to read this excellent quick start guide. You can also post questions and discuss the features on the image effects forum.
Version 2.0 is VR optimized
Version 2.0 of the stack is VR-ready, resulting in faster performance in VR games and content. A couple of highlights include scriptable access, so you can change effects at runtime, and the availability of volumetric profiles and profile blending.
Note however that there are a few effects that are not recommended for VR content as they will cause nausea, namely, Depth of Field, Motion Blur and Anti-Aliasing TXAA.
To learn more about using the stack in VR content, tune into this Unite session, VR techniques, tips and tricks, at around the 15:30 mark.
The latest blogs on the stack
Neon: Veselin Efremov is a writer and director on the Unity Demo Team who’s overseen both Adam and The Blacksmith. Over one weekend, he created Neon, a small but beautifully detailed environment using only tools from the Asset Store.
He brought in the post-processing stack right from the start; as he writes, "No reason to leave ‘post’-processing for last. In my workflow I start with it as soon as there is something to put in a scene...because I like to use the high quality effects and lighting to guide my creative decisions later on."
Linear rendering: Finally, read about how the new Linear rendering option for WebGL 2.0 in 2017.2 allows you to use the stack, including temporal anti-aliasing, and get really good results with WebGL.
