Looking for help with one unchanged 4K/8K resolution test

Hi, I’m working on a hobby strategy-game terrain using Gaea Community. The terrain covers a large area, and after testing it in Godot, I found that the 1K height export appears to be the main limitation on steep mountain slopes.
Before deciding whether to purchase Gaea Indie, I would like to compare the exact same graph at genuine 4K and 8K resolution.
Would anyone with an appropriate paid Gaea licence be willing to open my .terrain file and run one unchanged 4K and one unchanged 8K height build for testing?
No terrain editing or artistic work is needed.

I would provide the exact Gaea version, requested output settings, and screenshots. The purpose is simply to determine which resolution my project actually requires before purchasing.
I can share the project privately with someone established in the community. A small tip for the time is also possible.

I understand that 1K across 200 km is extremely sparse and that regional/tiled workflows or a smaller authored scale may ultimately be preferable. Before restructuring the terrain, I would like to compare the unchanged graph at 4K and 8K so I can determine how much of the current artifact is resolved by source resolution alone.
