Attempting PBR relighting in Nuke

(If you're just here to find the tool, scroll straight to the bottom. If you want a little bit of the history of how this tool came to be, read on.) Over the year, I've tried my hands a few times at getting better results doing relighting in Nuke. As much as I love working [...]

Nuke Notification Panel

For once, I decided to showcase something in a Video instead of writing a big wall of text. It was just easier to show the result. I started thinking about making a Notification Panel for nuke a couple of years ago, but never had the time to bring it to a decent level of completion. [...]

Make a custom advanced Keyer using STMap.

Even though it’s the compositor’s bread and butter, Keying can still be a particularly painful subject. I’ve been pulling keys for over a decade, yet it is often scarier than comping a full CG realistic shots with projected matte paintings and volumetric smoke. One can never have too many tools on their belt for pulling [...]

Playing with Higx PointRender

For the very few of you who have missed it, the talented Mads Hagbarth recently released his Higx PointRender. While the tool is not free, it’s pretty affordable compared to what some others might charge for tools that can accomplish this much. There are a few video tutorials on the official website, plus some experiments on [...]

Level up your Python game

This post if for the artists who have been dipping their toes in the water of Python development and are considering taking it to the next level. We will cover some of the points that differ between an artist/amateur level of development and an entry TD level.  I’m covering quite a few subjects in this [...]

Merging 2D Transforms in Nuke

Since I discovered that Nuke was concatenating Transform nodes for me, I liked to break out my transformations into multiple nodes to give me a bit more flexibility. I would do a stabilize, some keyframe animation, scale up a bit, rotate for a while, matchmove, re-scale, in different nodes. Nuke was smart about it, and [...]

Create Position Reference (Pref) Pass in Vray for Maya

While Vray is remarkably intuitive for some daily operations, others might require a much more convoluted process. The creation of non-standard render passes, and especially the “Pref” pass is one of these (read that P-ref, like you’d read T-Rex). A few tutorials cover how to render custom render passes (a.k.a. AOVs) such as this one [...]

Maya Python: Renaming Duplicate Objects

While it may not sound like a big issue at first, I recently realized that having duplicate names in Maya can be more problematic than I originally thought. Maya handles these duplicate names by using a “long name” internally, but some other scripts (including some default scripts) will complain about it and constantly throw error [...]
