FBX_RosePetals_v29x.zip – Contains a new Blender 2.9x file EEVEE ready (works with Cycles too) and also .FBX files with bent and flat petals so you can use them in other 3D applications. Make sure to unpack this file in the same location as the previous version so that the texture path will read correctly.
If your 3D application can import .fbx files, you can import the bent petals collection which is useful for depth closeup scenes. You can also check the flat petals meshes and use them as emitters on Unity, After Effects or any other 3D authoring environment.
These files are useful for celebration scenes such as valentine’s day, king’s crowning days (videogame), or special celebration titles:
