Technical and Research
These are some of the videos which I found useful when researching how to use MASH for set dressing.
MASH – Placer Node
This video shows how to scatter geometry using the brush-like placer node. I found that MASH only works in cm. There is an option to set “strict no collisions” but I found that my geometry was still colliding no matter how I played around with the settings. It therefore took a lot more care in placing geometry than what is shown in the video.
Set dressing using MASH Placer Node & Arnold Procedural /Standins
This video introduces the workflow of scattering low-poly geometry with the mash placer node which are then swapped out at render time with the detailed versions. The arnold help page on An Introduction to Stand-ins shows how to export geometry as stand-ins and be re-created as bounding boxes in the viewport. So far we haven’t had the need to use this method.
Maya 2017 – Intro to Mash
This video introduces how animation from an origin mesh can then be duplicated and controlled with a time node. This node is only available with non-instanced MASH and therefore requires a low to high number of meshes workflow.
MASH – World Node Clusters
I looked into this as an alternative to using the placer node. An option in the World Node allows you to generate clusters of geometry around the first geometry ID in your network.
