Hey Liam!
Thanks for submitting this bug report.
I was not able to recreate this issue on my end:


Here my project file:
https://www.dropbox.com/scl/fi/pi6ip5ek ... pqbz1&dl=0

Some troubleshooting questions:
In what program are you seeing this issue? After Effects/Fusion etc?
What render settings did you use (Layered? What compression setting (DWAA/ZIP etc?)
What hardware are you on (GPU)?
Would you mind sharing the exr file?

If you want to help us troubleshoot this issue other things you can try:
1. Update to latest version of solaris if you aren't already
2. Export it as orbx, and load it into octane standalone. If the issue persists there it could be GPU/Octane core issue and we can pass it on to the core devs.

Thanks for your help figuring this out!
