In this post I will show you how to execute a Houdini (or any other) job remotely on a Windows machine. The remote machine in our case did not have a GPU and my goal was to make it automatic so the job was started from command line.
I would like to share with you a small setup I did for artistic style transfer. I won’t go too much into technical details, rather I will describe my motivations and what problems I tried to solve.
Style transfer example taken from fast-style-transfer.
Style transfer can easily produce quite interesting results unlike filters we already know from e.g. Adobe Photoshop. While style transfer might be cumbersome to set up and control, it is definitely an interesting image processing technique to experiment with and which can produce novel looks.
I would like to share a small convenience tool for upversioning modified (unlocked) assets.
In the next couple of posts I will be describing photogrammetry workflow which I am creating for a student production. I am planning to describe here the whole process, from processing pictures to exporting game-ready assets. Game-ready assets because our production requires realtime renderings, but the process can be easily altered to produce VFX-ready assets (but this will probably require more manual work e.g. retopo, UVs to meet stricter quality requirements).
I have a tight schedule for this project, so I will try to stay simple, efficient, but try to be as correct as possible.
In this post I will describe our photos processing setup and colors workflow. This will result in photos with mask in alpha channel and in linear color space, ACES in our case. After that the photos should be ready for photogrammetry software, but that is for another post 🙂
I recently started to help out with photogrammetry pipeline for a student project. I would like to do artist-friendly yet accurate and proper workflow. It should be as automatic as possible. But that I will describe more in depth in other blog posts.
One of the first steps of our workflow is to process raw images (Canon’s .CR2 in our case) into something Nuke can handle well. In this quick tip I will show you a simple tool I adapted for this purpose and how you can use it directly from Nuke.
Sometimes it is useful to have NumPy module available in Nuke’s Python. It contains powerful tools for image processing and is required by some gizmos, e.g. mmColorTarget.
Setting up NumPy on Linux is usually just a matter of running “$ pip install numpy”, but on Windows it can get tricky.
In this quick tip I will show you how to easily take advantage of Houdini’s NumPy which was compiled with the same compiler as Python in Nuke.
In this post I will discuss couple of ideas about versioning of Houdini assets.
Keeping track of your changes is important in every workflow and the same applies to dealing with digital assets in Houdini (HDA/OTL). Houdini enables you to have non-destructive workflows and has a nice way of managing its assets versions.
I think that those useful features might be a bit hidden, so I thought I could write something about it 🙂
