List of TER.OPTION parameters

Hey all. As you may or may not know, .TER files can have .OPTION files, but the different parameters and what they do isn't documented anywhere, so I figured I'd at the very least list them all here and make some guesses (based on the ones used in the stock maps).

Code: Select all

-lowres_numpatches <int>    // base number to subdivide total area of terrain by for low-res terrain
-lowres_patchsize <int>    // number to subdivide each low-res terrain patch by
-maxlayers <int>    // hard limit for the number of texture layers
-watercutter_patchsize <int>    // unknown, found in dea1 and nab2
-reducewater <int>    // unknown, found in dea1

More on terrain patches: https://docs.unrealengine.com/udk/Three ... %20Patches

For example, if your terrain is 128x128 and lowres_numpatches is set to 4, the area of each patch would be 32x32 (since 256 / 4 = 32). The actual *resolution* of each patch is determined by lowres_patchsize, which is the patch's geometric subdivisions, so if lowres_patchsize is 2, the resolution of each patch would be 3x3.

What the normal terrain would look like:

If anyone else knows anything about these parameters or if I'm wrong about something, please say so!

I think watercutter_patchsize is related to how big each "piece" of water is.
