r.Substrate.ClosuresPerPixel

r.Substrate.ClosuresPerPixel

#Overview

name: r.Substrate.ClosuresPerPixel

The value of this variable can be defined or overridden in .ini config files. 2 .ini config files referencing this setting variable.

This variable is created as a Console Variable (cvar).

• type: Var
• help: Substrate closure count per pixel can be constrained. That is usefull to reduce the number of byte written durting the base pass, but also to limit the number of closures in Forward. Higher value means more complex material can be represented.

It is referenced in 2 C++ source files.
