I will go briefly through the process of setting up Houdini on a headless linux server.
In our project we had access to Nvidia VCA hardware which was running CentOS 7.3 and did not have a X server.
This hardware has some decent computing power in it and we wanted to offload some of our rendering on this computer. We were rendering with Redshift renderer which scaled pretty well on multiple GPUs. We also just fitted into Redshift’s limit of max 8 GPUs.
To be able to do more general-purpose jobs (simulations, caching) on the VCA and to simplify submission process we decided to setup both Houdini and Redshift on it.
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.
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.
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.
