All newsPlayers around this dateRead on Steam

[b]WARNING: This version is not backward compatible. Any file you save in this version will NOT load in any previous version.[/b]

After release, if you wish to remain on a previous version, you can by using the following codes:

v1.7.1.4 Steam Code: v1714LOVEPLANET

v1.9.0.6 Steam Code: v1906CO2Was298

Changes:

v1.9.0.6

- FIX: Track texture being stretched under some circumstances.

- FIX: Track Bezier Control Points were not being set at first click, only upon first move.

- FIX: Self-join track should hide the last cross-section and keep it in synch with the first cross-section.

v1.9.0.5

- FIX: AC direct export not setting timing gates properly.

- FIX: Nodes Height Smooth & Straighten not working if selected nodes fell across start/end.

- FIX: Some popup menus not being made visible again.

- Modified: Right click on the Track Roll Strength to reset to Zero.

v1.9.0.4

- FIX: Some surfaces, when placed close together will not cross a row.

v1.9.0.3

- Improved: Sped up Terrain calcs, especially for larger maps.

- Fixed: Importing a corrupt FBX file would crash RTB.

v1.9.0.2

- Fixed: Race locks between render/hittesting and background calcs.

v1.9.0.1

- 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.

v1.9.0.0

- 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.

And just in case you're jumping from 1.7* to this ... v1.8 includes:

v1.8.0.0

- Added: Direct export to Assetto Corsa.

- Added: Import Fbx files without need for XPacker.

- Added: Naming of Tracks so their name will appear in the export.

- Added: Invisible material and texture for Hidden Walls and Collision objects rather than reusing first texture.

- Added: Ability to switch Edit Modes using 1,2,3,4,5,6 keys.

- Added: Switch Tools using ` key (tilda ~).

- Improved: FBX Export. Removed duplication of materials by re-using them across different meshes.

- Improved: Add Object to roadside better at calculating density.

- Improved: Minimum initial Venue size reduced to 500.

- Improved: Added button to select new object/string/wall rather than having to double-click.

- Improved: Use listboxes instead of comboboxes for object/string filtering.

- Modified: RTB Setting now under the Edit menu instead of File menu.

v1.8.1.0

- Added: Smartly split large Terrain by grouping by Polygon location rather than just by the Index buffer.

v1.8.1.1

- Improved: AC Direct export now creates unique String Objects names.

v1.8.1.2

- Fixed: AC FBX export hierarchy not working properly for nested objects, i.e. Moveables, 3d tree.

- Improve: 3d tree so trunk, branches and leave LODs out sooner. LOD model LODs in sooner to avoid disappearance.

v1.8.1.3

- Fixed: AC FBX export String Objects not being offset correctly.

v1.8.1.4

- Improve: AC AI left/right borders set using Centerline Road Left/Right and Pitlane Road Left/Right instead of being hard-coded.

v1.8.1.5

- Fixed: FBX export fix for DiffuseSpecular material.

Enjoy!
