Animation Nodes 2.0 released

I'm proud to present Animation Nodes 2.0. Previously my main focus was to achieve high flexibility. This allowed me build a very expressive general purpose node system. At this point, I can slowly start to focus on optimizing AN for common cases. This will result in an addon that is more user friendly. Features like falloff and vectorization (read the release notes to learn more about that) really aim at simplifying common tasks.

As a nice side effect this also allows for great performance optimizations from my side. Some nodes are up to 400 times faster now. Those high speedups are also possible due to the introduction of a new programming language called Cython. Unfortunately this also means that AN is not OS independent anymore. You will have to select the correct version for your operating system to make it work.

The manual improved at lot as well. This is all thanks to Omar Ahmad who spend many weeks to write an initial documentation for every single node. More help is always welcome though!

We worked hard on the release notes as well. They contain many examples, so wherever you want to begin, you can jump right in.
I have many more ideas that I will try to implement on in the upcoming months. Most notably I'm planning a new action socket which will be a huge deal for many motion graphics effects. Furthermore I finally want to have a good template system, a rewritten color system, an improved mesh data type and much more.

In a few weeks the current semester ends and the most productive time of the year starts. Then I have to decide whether to look for a summer job or to work on Animation Nodes as I did in recent years. To be able to afford the latter I need your support. Please checkout my Patreon page and consider to make a small monthly donation to help me to continue to amaze you.

Weekly Blender Developers meeting notes - July 9, 2017

1) Blender 2.79 release
2) Blender 2.8
  • There's a tracker for Blender 2.8 issues, but this is currently only open for those who are involved.
    If you need the url or want to know if it's worth adding, ask one of the regulars.
  • Antonio Vazquez reminds us we like to see a (temp) splash for the 2.8 branch. Proposal: we switch every month (on the 1st). Each time one 2.8 dev can select a splash, and selects a splash judge for next month. Before committing, splashes need to be checked by one of the core devs or run it via me :)
3) GSoC and other projects
  • All students passed the first checkpoint. However, some of them under probation. Now is the chance to shine! Want to be involved, join the dev list.

Blend4Web 17.06 LTS

Основные изменения:
  • Экспериментальная поддержка Augmented Reality (Дополненная Реальность). Технология Дополненной Реальности — это возможность вывода компьютерной графики поверх изображения, передаваемого видеокамерой. Подобная технология позволяет реализовать качественно иной уровень восприятия компьютерной графики. Разработчики Blend4Web подготовили специальное приложение демонстрирующее поддержку этой технологии фреймворком. Как всегда, исходные тексты можно найти в дистрибутиве SDK.
  • Поддержка ограничителей Blender. Ограничители (constraints) Blender предназначены для определения правил поведения объектов и их взаимодействие в сцене. Разработчики Blend4Web обеспечили поддержку группы ограничителей, связанных с копированием данных трансформаций: Copy Location, Copy Rotation, Copy Transforms. Также в этом релизе работает ограничитель Track To, позволяющий задать «слежение» объекта за целью. В качестве примера, было подготовлено простое приложение, где демонстрируется использование Copy Rotation. Обратите внимание, что «честная» анимация присутствует только для движения рукояти. Вращение остальных элементов механизма обеспечивается ограничителями.
  • Новый алгоритм освещения для материалов Cycles. Теперь использование материала с нодами Glossy BSDF и Diffuse BSDF автоматически включает освещение от окружающей среды, которое учитывает параметр шершавости материала.
  • Изменения в редакторе логики. Была добавлена новая нода Set Camera Limits, позволяющая контролировать перемещение камеры. В совокупности с узлом Set Camera Move Style пользователи фреймворка получают мощный механизм контроля за поведением камеры.

Editing Video in Blender 2.78

In the video, a free python script is applied adding a keyconfig which remaps shortcut keys to be more like Final Cut Pro or Premiere.

I take the novice from initial project set-up, through customising the Blender interface, adding media, transitions, working with meta-strips, and even editing audio.

This is a start-to-finish, easy to follow tutorial which requires no prior knowledge of Blender. A link for downloading the Python scripts is supplied in the video description.

Grease Pencil 2.8 sneak peek

Daniel gives us a quick sneak peek on the new Grease Pencil in the upcoming Blender 2.8.
The new Grease Pencil’s main focus is to create a more friendly interface for the 2D artist, while keeping the advantages of having a full 3D suite underneath. Grease Pencil is no longer just a stroke, it’s now a real Blender object with huge improvements to brushes and tools. 
Credits go to the Grease Pencil developers Antonio Vazquez and Joshua Leung. While Daniel Martinez Lara and Matias Mendiola support the developers with demos and testing. 
This development is currently happening on the ‘greasepencil-object’ branch, based off 2.8, and it will be merged soon so everybody can test using the build-bot.

Tutorial: Blender Character Modeling For Beginners

Here is a new free online video series for beginner blender users I am working on where I will show how to create a high quality 3D character design from scratch without using any reference.. Here is the first lesson from this series where we will start to model the human head using a formula based system that anyone can follow. I will follow up with the next tutorial soon.

Blender Cycles: OpenCL now is on par with CUDA

Cycles has a split OpenCL kernel since Blender release 2.75. It's an alternative approach to what is used on CPU (so called megakernel). 
The idea behind splitting the kernel is to have multiple smaller kernels which are not only simpler and faster to compile, but also have better performance. 
Initial split kernel patch was done by AMD. Further work was also funded by AMD. 
The OpenCL Split Kernel now supports nearly all features. Only Correlated multi jitter is missing. 
Baking works, but uses the mega kernel. Volumetrics, SSS, Branched path tracing, HDR lightning and Denoising are fully supported. 
With current drivers, all production files from the official cycles benchmark pack, including the huge one from Gooseberry, render now pretty fast.

Blender developers meeting notes - April 9, 2017 4

Here are the notes from today's 14 UTC meeting in irc.freenode.net #blendercoders.

1) Blender 2.79 targets
  • Updated the target planning. We still need to get all reviews done.
  • OpenHMD patch review will happen wednesday, Brecht van Lommel will help reviewing the Denoiser.
  • Alexander Romanov has a patch he would like for 2.79.
  • Bastien Montagne: PBVH painting review is nearly ready, just has complex side topics to tackle.
  • Sybren Stüvel worked on several Alembic IO fixes. This will go to 2.79 as well. (Keep posting or sharing Alembic files in public, please!)
2) Blender 2.8 projects
  • Dalai Felinto made an OpenGL and Viewport project priorities list.
  • Proposal is to gather the combined efforts of all current full-time coders to do the last OpenGL migration work. That will make Blender compile pure in OpenGL 3.3 Core Profile. Systems not supporting OpenGL 3.3 or later will not run Blender 2.8.
  • For everyone who doesn't understand "Core Profile", info from Khronos: "In 3.2, OpenGL was effectively split into two profiles, core and compatibility. An implementation was only required to define core, so compatibility is not guaranteed to be available.". More reading here and here.
  • Build bot now has working 2.8 builds.
3) Other topics and GSoC
  • Next week (Easter Sunday) is IRC meeting as usual. Might be less crowded :)
  • GSoC reviews are in progress: reminder for mentors to check!
  • Development Fund gave a 3 month grant to Hristo Gueorguiev ("nirved") to work on OpenCL optizations for Cycles.

Blender3D / Free Add-on: Real Camera 2

Real Camera 2.0 is an Addon that organizes the Blender Camera values.
With this update, now the values are physically based. This means that if you change the Aperture from 2 to 1.4, you are also doubling the light,. You need to have Filmic installed for the correct working of the Addon.

This update also introduces Auto Focus Baking for Animations and Auto Exposure for people who don't want to use real camera values.
Here is the list of the changes:
  • Physically correct Values
  • Autofocus 1000x faster
  • Autofocus Baking for Animations
  • Auto Exposure
  • Auto Updater
  • Time in the Timeline

Improving Alembic support in Blender 2.79 and Blender 2.8

Blender 2.78 saw basic Alembic support for both import and export. The initial patch was provided by DwarfLabs, and was then integrated into Blender by Kévin Dietrich. For the previous month, I (Sybren) have been working on bringing Alembic to the next level, and that work isn’t done yet.

This means that things are going to change; for the better, of course, but it may also mean requiring a re-export of your Alembic files. In this blog post I want to sketch my plans, and collect feedback from you, our dear Alembic users.
Broad plans

The final goal of my work is to be able to take an animated character, like Hendrik IJzerbroot a.k.a. Agent 327, and export it to Alembic for further processing in either Blender or other software. Furthermore, we want to be able to take animated characters from other software and load them into Blender. This includes support for:

    Instanced geometry
    Dupli-groups and dupli-objects
    Hair and particle systems

Furthermore, we want to change the workflow so that it will be easier to re-export characters by coupling export settings and collections of exported objects, giving the artist more control over what is exported exactly, and automatically (re-)apply certain modifiers and materials upon import.

Part of this work can be done for Blender 2.79 already, while other parts will have to wait until Blender 2.8.

How to make an animated flag in Blender3D

After looking through a lot of videos I got idea to make 1 minute tutorial where I will show you how to make flag animation in 1 minute. To get best results I used cloth physics and wind field. On the end there is trick in which you can see how to mae flagpole which will be followed by flag.

Blender developers meeting notes - February 19, 2017

1) Blender 2.78 'c' release
Reminder, the 'c' was needed because:
  1. OSX build had wrong CUDA kernels.
  2. GLSL viewport is broken when Light Path node is used
  3. Crash of material preview when using Image sequences
We had some delays last week, fixing was needed in Cycles motion blur. This Tuesday the last backport will happen to the release branch. Thursday we then can release 2.78c.

2) Blender 2.79 targets
  • We'll discuss this week with Mai Lavelle and Hristo Gueorguiev ("nirved") if SSS will be added
    to OpenCL split kernel.
  • Joey Ferwerda: HMD viewport development is on track, OpenHMD is doing a stable release specially
    for a Blender merge by end of the month. Will work on this with Julian Eisel to wrap it up and test it well.
  • List of open issues in bug tracker and patch reviews is still too long...
  • Note: Next week the release targets should be frozen, and we move to BCON2.
3) Blender 2.8
4) Other projects
  • blender.org servers might get down for maintenance Monday or Tuesday. We will notify the list first. Expected downtime not more than 5-10 minutes.
