– Computes the seed based on the instanced ID. User Attribute – Computes the seed based on the used attribute ID. Auto – Computes the seed based on a unique and random ID for each object. User Attribute – Specifies which user attribute to use the randomization source. Transform – Specifies the projection space: Local ObjectHoudini to Maya Alembic Workflow

. By Poly Shell – Randomizes color/texture per poly shell of an object. By User ID – Randomizes textures based on a User Attribute assigned to the specific objects and set in the User Attribute field of the VRayMultisubTex. Switch texture – A floating point value that calls the texture from the Texture List (below in the UIObject Properties

Object ID – Specifies an ID … the same illumination samples when using raytraced multiple scattering. This avoids illumination seams between those objects.

non-empty group of the input geometry. You can use a String Primitive Attribute to partition the geometry into separate Shapes. You can do this from the ROP Alembic Output → Hierarchy tab → Partition Mode: Use Attribute Value. This generates a separate Shape in the Alembic file based on a user-specified StringChaos Cosmos Browser
