Steam Beta Code: J3H5G6DJHBEDF
Changes:
- Improved: Track pieces between Nodes are now treated as individual Sections for faster calculation, finer control and better handling of intersections. Hierarchy is now set at Section level rather than the whole track.
- Added: Track surface smoothing at intersections. The track being cut is the one that is smoothed as it approaches the intersection.
- Added: Tracks default to True for Cut Terrain, Cut Tracks and Cut by Tracks. Turn off using the Section Popup menu.
- Added: A Track can now join with itself.
- Added: A Track can be Split into multiple Tracks. Select a Node and select "Split Track" from the popup menu.
- Added: Remember what monitor RTB was on for next time.
- Modified: Delete Track is now done via a popup menu - right click.
- Modified: Node (Track/String Objects/Walls) & Track Shape Point selection changed so that you no longer need to hold shift in order to move all selected points.
- Improved: No more hiding of the tool panel and menu.
- Improved: Use Perlin Noise for Track & Wall Surface Randomness for a more natural look.
- Improved: Nodes are scaled according to distance from the camera to make them easier to select when zoomed out but also not too large when closer in.
- Improved: Control Points are easier to identify with line connecting them, highlighted in yellow when hovered over.
- Improved: Object hit test speed.
- Improved: Middle Mouse wheel scroll uses detailed hit test for more accuracy.
- Fixed: Normals not re-calculated sometimes at the edge of a Terrain Raise/Lower event.
- Fixed: Some Normals not calculated properly when multiple background threads attempted to calculate at the same time.
- Fixed: Prevent camera from going underground when using Tab to cycle to new positions.
- Modified: Changed Track camber to be a Trackbar.
- Modified: NumericUpDown controls replaced with custom ones. Hover over and use scroll wheel to change, or type a new value.
- Removed: Track Length Warning. It's still best you have multiple tracks, but not so critical since Sections work.
- Added: Delete object, String Object, Wall using Popup menu. Available in relevant Move modes.
- Improved: Sped up Terrain calcs, especially for larger maps.
- Fixed: Importing a corrupt FBX file would crash RTB.
- Fixed: Race locks between render/hittesting and background calcs.
