Version 0.260 is heavily focused on new ground/terrain editing tools and improvements. These tools add more complexity/potential to terrain generation, and I know they are not exactly intuitive. I intend to make a video about the terrain stuff, but I just don't have enough time to do it this week (due to important non-work stuff).

Rather than delay the build itself, I decided to release it now, as there are some other gameplay fixes that I want to get out there sooner than later. There's also a new sandbox map, Oasis Test, that replaces Bridge Tester. It's not finished, but it shows some smoother, more "hilly" terrain and has a couple of the new path-style terrain loops. There's still a little refinement to do on the terrain editing, but it's pretty close to final. Next week I'll wrap up the refinements and do the tutorial video for Terrain mode (formerly known as Ground mode). Here's the full changelist:

GAME/BUILD MODE:
Fixed the up/down arrow between controls (made it swap instead of selecting both which made no sense)
Fixed flex treads not working with auto-braking
Fixed direction of changing override sounds in the UI being reversed
Fixed flex panel/triangle/etc not going up to 10 in length/width slider UI adjustments
Fixed fog still being active even when it shouldn't be
Fixed bug with camera mod in FPS mode not working when more than 1 is present

EDITOR:
Added new option to use loops as paths instead
- Creates a road/path instead of a loop
- Path points can be moved vertically (independently), unlike normal loops
- Path points have width, y-offset, and slope offset values
- Does not use Upper or Structure-based grass/rock generation
- Control over side generation is start/end/left/right, not per point
Added per-type filters per loop for grass/rock generation
Added Negate option (and Negate Offset) to cancel out grass/rock generation
Added some wider slope widths for loop generation (5x1, 8x1, and 12x1)
Added control over grass/rock tolerance curve slopes (Hold CTRL while editing to see/edit slope with LMB y-motion)
Increased maximum amount of grass points to 360k from 230k (rock points unchanged)
Changed how grass generates on low-angle slopes/edges/etc for more organic terrain
Changed Upper grass/rock generation to only generate within the loop boundaries (instead of everywhere)
Added "Noise Affects Top" option for loops
Made per-loop noise available for all loops
Added backup point highlighting for loops so you're less likely to accidentally select nothing (and deselect the loop)
Resvised how ground plane rock generation works to be simpler, faster, and better
Added tooltips to all more slider settings and named some a bit better
Added SHIFT functionality to editor sliders (slow increments for fine-tuning)
Changed loop mesh generation so triangles below a ground plane are now removed
Renamed Ground mode to Terrain mode to make it a little less ambiguous
Changed Skew settings to affect all loop vertical profile types, not just custom profiles
Fixed arrow keys not working to move camera in Normal cam mode in editors (and fixed Control not speeding up arrow keys)
Fixed editor camera switching to weird modes when going back and forth to build/play mode
- Known issue: orbit cam is still the best for testing, follow/iso change to orbit
Fixed issue with using skew and noise on the same loop
Fixed grid grass/rock generation to not generate stuff outside the borders of the loop (most obvious in ground-plane maps)
Fixed editing some values only changing the current loop instead of all the selected ones

If there are any urgent fixes (hopefully not), I'll be able to get them done for another 16 hours or so. After that, you'll have to wait 'til next Monday.
