バイオームデモ (Biome Demo)

日本語字幕をオンにしてビデオをご覧ください。

現実世界のバイオームの特性、環境からの影響、植物同士の関係に基づき、植物を配置する方法を見ていきます。この解説付プロジェクトでは、SideFX Labs からリリースされたアルファバイオームツールセットの各ツールを紹介しています。

この高度で科学に根差したシステムは、自然界の根幹をなす様々な営みを見本にしています。ユーザは、複数のバイオーム領域を生成し、それを使って最初の環境系アトリビュートを地形上に配置していきます。これらのアトリビュートは地形によって変化し、雨蔭や風への露出、土性、標高に伴う気温変化といった環境由来の様々な影響を再現します。その後、各々に適した気象条件や土壌を持つ領域に植物がマッチングされます。それらの領域では養分を巡り、周囲の植物との生存競争が繰り広げられています。

一部のバイオームツールには 20.5以降の Houdini が必要です。

    Thanks very much for that!

    I gave the tools a good go a few months ago. one thing I did at the end that I wished I did sooner was test my plants in a grid with temperature rising in X and precipitation rising in Z. this simple grid with not too many plants scattered showed me why some plants were not covering areas I thought they should. I could see where there were places where no plant would grow and when I blurred values in temperature and precipitation, it made inhospitable areas. I ended up tweaking some generic shrubs to fill in areas like that. Perfect for debugging

    Hi Bailey, I'm going through the example scene and I'm having trouble getting the instanced plants into Solaris from the SOP level. I have a hunch it has something to do with the way the instance paths are assigned to the points, or @instancepath attrib. When using the Plant Definition node and sourcing from disk it generates a path to the asset on disk, VS sourcing from a merge node it generates an op:* path to the imported assets. When merging in the instances using the direct file path to the asset, soloraris returns an error, but using the define plants from merge it seems to work fine.

    Example:
    Source "From Directory" @instancepath
    = F:/git/SideFx/SideFXLabsExamples/projects/dryad/alpha/biome_demo/assets/mesh/SM_Alpine_Forest_Shrub_Growth_1.fbx

    Source "From Merge Path" *Done inside of a lops Create Sop Node with megascan assets*
    = op:/obj/Scatter/lopnet1/sopcreate1/sopnet/create/Var11_LOD0

    Do you think an update to the Biome toolkit Example scene can include a Solaris setup?

    Thanks!

      Hi Travis,

      Good find. It seems the instanced assets in Solaris will only work with operator paths or usd files. I will fix the referenced geometry and add a Solaris setup to the updated file. Thanks for bringing it to my attention.

      Thanks,
      Bailey
