Learning resources about VFX and CG

I would like to share with you a collection of presentations, research papers and theses on various topics of VFX or CG.

lib_cover

I am used to collecting good learning resources and keeping them around in case I will need them later. So it happened that my small list grew and I realized that I have quite interesting things collected from various places.

So I decided to create a repository at GitHub where I will continue to gather useful information which I come across. I am not trying to re-create a database of all recent cutting-edge research. It is more oriented on resources which are easier to understand, like presentations with notes and pictures 🙂 I have been most interested in resources about FX and volumetrics, so it is missing stuff in other areas like cloth simulation etc..

And this is also one of the motivations to host it on a git: similar-minded people can contribute with their areas of interest and hopefully we will end up with a nice pool of information which we can quickly refer to when needed.

I tried to make an easy system for adding new entries – simply add them into a json library file and the page will be automatically updated. More info about that in the repo.

I hope that you will find this resource useful 🙂

Houdini tip | Houdini Python modules documentation

Hello,
in this post I will present you a small project I did recently. If you have spent a lot of time digging in Houdini undocumented Python modules, then this might save you some time.

UPDATE: Now there are more modules documented and I changed my workflow, see notes in repo.

Batch textures conversion tool

Hello,
I would like to share with you my latest tool that I developed in my spare time. It’s aim is to help you with batch pre-conversion of textures for VFX render engines.
It will batch convert your textures into formats like rat (for Mantra), tx (for PRMan or Arnold), rstexbin (for Redshift). It works within Houdini, Maya or as a standalone application. You can see screen capture of this tool in action here 🙂

Houdini tip | Open parameter path in file browser

Hello,
in this post I will show you a small convenience trick. It will help you with locating files in your OS file browser, opening images in Mplay or any other application like Djv_view, RV.., directly from Houdini parameter window.

UPDATE 1: Fixed RV script to open folder with whole sequence instead of just one frame
UPDATE 2: Added Photoshop menu item, updated RV, mentioned Sequence From File package
UPDATE 3: On Linux, when opening in File browser, I clear LD_LIBRARY_PATH environment variable which may cause bugs in some situations, fixed some mistakes.
UPDATE 4: Fixed a bug, where Mplay opening script would incorrectly expand $OS variable in file path.

Houdini tip | Render any node in background

Hello, I would like to share with you a recent small script I did for more convenient local rendering from Houdini.

node_tree

In some Houdini builds I had issues with background renders, and I also miss Background render feature on some nodes. So I created this shelf tool, which will enable you to start a background render of a selected node or nodes. Using this tool you can render nodes with dependencies, fetch nodes, merge nodes… Just select the node and press button. It will start up a background process in terminal, where you will see progress of the rendering.

Currently it works on Linux and Windows. Feel free to contribute to the repository and extend it for MacOS. Also if you encounter any issues let me know, or even better create a pull request 🙂

Here you can find script repository with set-up instructions.

Happy rendering 🙂

Houdini tip | Using HOU module in Visual Studio Code

When developing Python tools for Houdini it is often more convenient to use an external IDE. However we do not want to miss Houdini’s neat auto-completion. In this quick post I will show how to set-up Visual Studio Code (VSCode) auto-completion for hou module.

UPDATE 1: Added Interpreter settings and config examples for Windows and Linux.
UPDATE 2: Corrected the part about hython, added a better solution, which does not break autocompletion.
