Why does render target saved as EXR clip?

Hi!

I am trying to export a render target as an EXR file. Here’s the setup:

Scene capture 2D component, with target source: Final Color (HDR) in Linear Working Color Space. No post-processing.

This is routed to a Render Target with RTF RGBA32f format (also tried RGBA 16).

I then use the ‘export texture to disk’ blueprint with EXR option and ‘1’ for the compression setting (should mean it is uncompressed).

This all works, but the exported image is saturated. The values range from 0 to about 100. I’m not sure why this would be, and trying out various changes to the options has not helped. Strangely, a post-processing step that multiples the color by 0.1 does not change the output either.

Any ideas how to fix this? Thanks!
