Can’t View EXR HDR Files in GPU Mode After Effects 2025

Since I switched to After Effects 2025 I can’t view my EXR HDR files properly when using Mercury GPU Acceleration (CUDA or OpenCL). As soon as GPU acceleration is on, everything caps at a max brightness of 100 and the highlights get totally clipped, whereas in Mercury Software Only (CPU) it works fine. In 2024 I could work in GPU mode no problem, but now I’m forced to stick to CPU.

Also, when I’m using OCIO, AE only shows me one view transform option in the UI, so I can’t preview any specific look unless I drop in the “OCIO Look Transform” effect. It’s really important for an EXR workflow to be able to see the correct look while I work

Hey Paul, thanks for the quick help! It turned out to be another system setting on my end, and now everything’s working perfectly with no more issues

Really appreciate it!

Additonal question:

Is this only occurring when Color Management is set to OCIO?

Greetings, Paul here from the AE quality engineering team here.

We've run some quick tests here and are not reproducing the behavior you are reporting — in the simple scenario of importing an EXR which contains overrange color values (>1.0 in 32bpc) and previewing them in a 32bpc Project on a system which supports HDR display.

Additonally, straight import-render-display of EXR footage does not process through a GPU pathway. That Project Seting should have no effect here at all.

So we need to get some more details here about your system configuration (particularly  that of your HDR display configuration), your AE Display Preferences settings, and an idication of your EXR and Project configurations that are causing this issue to happen.

If you could make an example Project+EXR which reproduces the issue available to us (direct message me with instructions to access it), it would be very helpful for understanding what the problem might be.

Thx!
