Unity just released a new sample “Spaceship” that demonstrates the new Visual Effect Graph showcasing it’s ability to create elaborate UI or in game special effects.

Details of the demonstration from the Unity blog:

The spaceship demo features many effects during its walkthrough. All these effects have been authored and optimized in-game production conditions with performance in mind, targeting 33.3 ms (30 fps) on Playstation 4 (base) at 1080p. All the effects are taking advantage of the many optimization settings we implemented in Visual Effect Graph and High Definition Render Pipeline.

Half-Resolution Translucent Rendering renders selected transparent particles at a lower resolution, increasing rendering performance by 4 (at the expense of little blurriness in some rare cases). We used it mostly for big, lit particles that are present in the foreground as their texel/pixel ratio is rather low, the loss in resolution is not noticeable at all.

Octagon Particles is an optimization of quad particles and enable the corners of the particles to be cropped.  where the pixels are often found transparent (invisible cost). Particle corners are often transparent, but the overlapping of these transparent areas result in unnecessary calculations. Cropping out these sections can optimize the scene up to 25% in situations where there is lots of overdraw. There is also the benefit of reducing the resolution of the translucent sections when they can’t be cropped away.

Simplified Lighting model: Simple Lit for HD Render Pipeline enables disabling properties of the BRDF – Diffuse Lighting, Specular Lighting, Shadow and Cookie Reception, and Ambient Lighting. By selecting only the features you want to see, you can decrease the lighting computation cost to close to none. For instance, particles can be lit using only Light Probes by selecting a Simple Lit Translucent Model, then disabling everything except ambient lighting. This optimization was chosen for many environment effects that did not require a lot of high-frequency lighting.


You can download the project from GitHub however you need to have git LFS support enabled.  You can also download a pre-compiled version as well as a zip of the complete source archive right here.

You can learn more about project as well as a complete capture of the Spaceship demo in the video below.

One of the most requested features in Unity, beyond dark mode in the free edition, is some form of Visual Scripting language like Blueprint in Unreal Engine.  Unity have been working on an experimental version of Unity Visual Script and earlier this week dropped the 3rd experimental version as well as a sample to demonstrate how it all works.  Keep in mind, this is extremely early and in no way is it for use in production code, nor is it documented… at all.

Another thing to keep in mind is the Visual Script in Unity is only for their new DOTS system, meaning it wont work with existing MonoBehaviour code.  It was explained why in the 2nd drop:

In this particular case we realised that there are quite a few mature solutions that most of the community is using successfully for visual scripting. We didn't think that what we can build on top of MonoBehaviours in terms of visual scripting would have been a massive improvement over solutions in the asset store.


On the other hand we saw an opportunity to focus VisualScripting on DOTS. Specifically enabling artists & level designers to write incredibly efficient multithreaded game code, by expressing their intent simply and the code being generated taking advantage of DOTS. The data centric nature of DOTS opens many new opportunities for visual scripting and interop with other code based systems.


We think a combination:
* Generating high performance visual scripting code out of the box (C# job + Burst + great memory layout)
* A UX language that reduces noodle graph-ness, by supporting stacking and other dedicated UX paradigm
* A straightforward path to transition from Visual Scripting -> well organized DOTS C# code
* Amazing debugging tools deeply integrated into DOTS & Visual scripting


If you are interested in a Visual Scripting system that works with existing Unity code be sure to check out Bolt or PlayMaker on the Unity store.  Check out the new Visual Scripting system in action in the video below.

The Unity game engine just got another stable version release, Unity 2019.2.   As always it is available for download right now using the Unity Hub.  Unity 2019.2 contains over 170 new features and enhancements including updates to the ProBuilder and PolyShape plugins, a new 2D lightweight renderer supporting dynamic 2D lights, ShaderGraph updates and much more.

In this release we got much more comprehensive release notes, split across several files.

Or you can watch the video below to learn more about this release.  If you want to experiment with the new lightweight 2D renderer and lighting options you can start by cloning this project that was used in the video.

In addition to their already released 2D Gamekit  (and the more advanced 3D Gamekit), Unity have released three new Gamekits to their Unity Learn portal.  The new gamekits include:

Each Gamekit includes a complete project downloadable from the Unity Asset store as well as a full step by step tutorial that average around 1 hour in duration.  They are designed to introduce users to Unity without requiring art or programming ability.  Each Gamekit is designed to be extended or customized by the user.  Learn more about the new gamekits in the video below.

There is a new Humble Bundle of interest to game developers, specifically Unity game developers.  This is the Humble Unity Game Development Bundle, and it consists of a collection of Udemy courses by GameDev.tv, mostly on the subject of Unity, although a few other topics such as Git and Blender are also covered.  As always the bundle is organized into tiers, where if you buy a more expensive tier, you get all of the content at the lower tiers. 

The tiers in this bundle consist of:

1$ Tier

  • How to Get A Job in the GameDev Industry
  • Finish It! Motivation and Processes for Game & App Development


20$ Tier

  • Locked content Blender Environment Artist
  • Git Smart: Learn Git The Fun Way With Unity Games


25$ Tier

  • Complete C# Unity Developer 3D
  • RPG Core Combat Creator
  • Complete C# Unity Developer 2D
  • Locked content Unity 3D Game Kit - Make Games Without Coding


All contents in the bundle consist of Udemy product keys, so you need to have a Udemy account and you have to redeem the keys within a year of purchasing.  As always you can decide how your money is allocated, between Humble, the publisher, charity and if you so choose (and thanks if you do!) to support GFS.  The bundle is available here, you can learn more by watching the video below.
