When integrating CG characters into a plate and something seems not-quite-right, the first solution I look towards is adding more occlusion shadows, often referred to as “Ambient Occlusion”. Occlusion shadows help ground our CG characters and really connect them with the environment & live-action characters around them.

Most physically-based render engines are capable of rendering occlusion shadow AOVs, which are quite accurate when given photometric lights, but sometimes mathematically real and visually real isn’t the same thing…

A common complaint I hear among compositors, especially those working on large shots is: “My script is so slow”. There are many things to consider when trying to speed up a cumbersome script, but the sneaky culprit usually reveals itself in the form of a ReadGeo node importing geometry over the network. Even when you’re importing basic…Continue Reading “Quick Tip: Disable geo when you’re not using it.”

Unless you’re Compositing at Weta, Nuke’s Deep tools are quite barebones and don’t allow much flexibility. An issue I have commonly encountered is a lack of image filtering when DeepMerging two Deep images together, which causes crunchy edges. You could correctly argue that this comes from a lack of deep samples in rendered images, but this is often necessary…Continue Reading “A hack to filter DeepMerge operations.”

SmartVectors, and the associated VectorDistort node is one of the best new additions to Nuke in recent years. Being able to effortlessly track a texture to an organically-moving object is amazing when it works, but oftentimes SmartVectors only gets us part of the way there and needs refinement… By changing the VectorDistort’s Output knob to “st-map”, we gain the ability to modify SmartVectors in…Continue Reading “Quick Tip: Refine SmartVectors with an STMap.”
