I just tried this on my system and was surprised at the amount of differences between the two test files.
Some differences, like "gui_network_view_position" would appear to be a normal (maybe due
to the OS?) Others look suspicious, like GI_relative_detail = "2" in the first file and
GI_relative_detail = "1" in the second.
Here's a list of suspicious (to me) differences
file 1 file2 note
GI_relative_detail = "2" GI_relative_detail = "1"
quality = "0.75" quality = "0.7529770606" in Easy Cloud
millions_of_voxels = "30" millions_of_voxels = "29.99682" in Easy Cloud
Okay, here's my guess at what's happening. When the user enter's values (not all values) like 30, it will likely
be something like 29.99682 in the actual program. However, in this case I didn't enter any values other than
add and easy cloud and hit render (for the first file.) Then saving the file after everything finished (including
the preview.) Then an exit and restart of Terragen. Load the first file, render and save (to a different folder)
and then the compare.
