EngineLook

3Dv1core

Overview

The engine look as a node on scene-linear input: exposure (stops) then the tonemapper 2014 UE Filmic (the fitted ACES curve UE ships), AgX, or Hable. This is how a render looks IN Unreal while every pixel underneath stays gradeable. none = bypass.

How to

How-to

Wire a scene-linear stream (EngineLive or a render); set exposure in stops and pick the tonemap.
Use it to match what the engine's viewport showed, or leave scene-linear for the comp's OCIO.

Parameters

Parameter	Type	Default	What it does
exposure	Float	0.0	Brightness in photographic stops: +1 doubles the light.
tonemap	Choice	UE Filmic (ACES)	Which view transform the live stream is shown through — Unreal's own tonemap, or scene-linear left alone for the comp's OCIO. `noneUE Filmic (ACES)AgXHable Filmic`
disabled	Bool	false	Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back.
label	Text		A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache.
hide_input	Bool	false	Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap).
