I don’t think I’ve ever noticed a green tint. Is this noticeable in Painter directly or when comparing to another renderer? Just to be sure, your Painter camera settings are clear of everything but the Log tonemapper, since the default setup has some things enabled iirc. The biggest issues I’ve seen in my primary renderer(UE4), aside from shading differences, is UE4 also includes a few adjustments to fake a wide gamut and to fix the “electric blue” issue. No obvious color tint that I’m seeing though
The stock linear EXR provided by Allegorithmic is already clamped between 0-1. You can see this with the stock Log LUTs too. There’s this older thread where my original LUT was shared, before I did the pre-transform and Nick provides a lot of helpful information ACEScg for Animation feature and further questions
