I am not sure where to ask this so I hope this is the correction location.
I have made and uploaded a patch for a mod on Skyrim LE. The original author has open permissions. I can easily convert and port my patch to SSE.
The mod however was ported by another person to SSE.
Do I need their permission to upload the patch even though I did not use their files at all and only touched the original LE ones? It still needs the original files though, which is what they ported for SSE.
