We have received reports of geometry occasionally disappearing during IPR. After further investigation, it appears a specific environment variable might be causing this unexpected behavior. If you experience IPR issues related to geometry suddenly disappearing during rendering, please try setting the "HOUDINI_ACCESS_METHOD" environment variable to "3".

Trace Depth Limit – Represents the maximum number of bounces that are computed for reflections and refractions. The individual material reflection/refraction depth settings are still considered, as long as they don't exceed the value specified here.

GI Depth Limit – The number of bounces for indirect illumination. Other GI settings (e.g. whether GI is enabled or disabled) are taken from the production V-Ray renderer.
