The Linked replacements settings allow you to specify whether V-Ray family replacements coming from linked files are treated with respect to the host file or to the linked file.
Discard – All linked V-Ray replacements are discarded. This allows for overriding the materials/families in the linked file.
View & Override – – Linked V-Ray replacements can be viewed, rendered or get overridden with V-Ray assets created in the host project.
Read-only – Linked V-Ray replacements are rendered but are hidden from the list. An override is not allowed. This mode can be used for reducing the list in the Appearance Manager.
Merge identical – When enabled, identically named items are hidden from the linked file list(s) and remain listed only in the main project section. Their replacements are based on those of the host project.
For example, if Tree_01 family is present in both the host and linked projects and Merge identical mode is enabled, Tree_01 will only be visible in the Project group of families. But when replaced with a V-Ray geometry, it will also override the Tree_01 family of the linked project.
