Two LUTs for Substance Painter(v2.5+) containing the ACES RRT and sRGB ODT to match other renderers more closely. Both LUTs assume a sRGB working space and have no impact on the materials or textures- they are limited to Painter's viewport only.
In order to use them correctly, Painter's Log tonemapper must be enabled. Activate Post Effects and Tone Mapping, restore defaults, and set the Function to Log, then assign the Color Profile.
ACES_Standard_Log contains the default RRT and ODT and should resemble viewers using full, or approximated, ACES as the tonemapping operators, such as Unity and Toolbag.
ACES_UE4_Log is designed specifically with UE4 in mind and includes a similar modification on top of the standard RRT that's present in UE4.
