This scene was a good excuse to experiment USD and MaterialX workflow in Houdini/Solaris. It was defintely a lot of fun, but also painful to get started. I will definitely keep pushing in that direction and share my findings on my youtube : youtube.com/adrienlambertvfx
For scattering I heavily used my "AL TOOLS " and the "AdvancedScatter" to quickly create complex scattering systems for all the different elements in Houdini. I have been working on a v6 that should really help make things easier and faster... This version won't be retro-compatible with past projects though as I am changing some core features. This update will be reflected in my current products and orbolt once I push the testing phase a bit more.
Yes ! There is a commercial and studio version of the tool available on Orbolt : https://www.orbolt.com/asset/AdrienL::AL_advancedScatter
Been using some megascan assets and plants for the creation of this illustration.
Using MC WorldKit's *Ivy taming* in Houdini for ivy generation. Check out his gumroad ! https://gumroad.com/a/763794547
Bought the Stag on Turbosquid and did the lookdev/groom back in Houdini Solaris.
Re-used some tree I made in speedtree a while ago and converted that into USD friendly elements.
