Scenery patch 12

Scenery patch 12 is now live with the following changes:

Editors

• Fixed possible crash in route editor

• Fixed possible train and timetable editor undo/redo crash

• Fixed LOD generation crash when switching quickly between train editor and simulation

• Fixed manually placed custom objects sometimes not appearing properly in route editor until refreshing

• Fixed direction selection to work correctly when editing a speed limit

• Made editor right-click popup scrollbar stand out better

• Simplified formation names in timetable editor when displayed as options

• Changed route editor to not create a track/road section between nodes if they're over 10km apart horizontally or 1km vertically, to prevent the editor from freezing

• Added ID number to model node choices in editors to distinguish between nodes with the same name

Editor side panel

• Added "industrial" object category to the route editor side panel. Moved some old models there and added new ones: chimney, cooling tower, mine headframe 1, mine headframe 2

• Added gradient auto-adjustment option to track/road properties in side panel

• Added route editor side panel option to automatically adjust node gradient when moving it

• Moved rarely used curve speed limit generation and cleanup options from right-click popup to the side panel in route editor

• Made AWS electromagnet link field editable in route editor side panel

Signalling

• Fixed vanishing custom signal posts

• Fixed disc signals sometimes appearing without disc or counterweight

• Fixed (LMS) semaphore signal appearing empty in some cases when max number of arms is set to zero on one side and non-zero on the other side

• Fixed possible wrong arm order in auto-updated semaphore signals

• Fixed incorrect main arm for some signals

• Fixed disc signal animation entity id when creating an editable model

• Added "disc signal post only" model (disc signal post without concrete foundation)

• Added "GWR backing arm" model

Custom models

• Fixed normal maps for custom models to work properly

• Fixed normal vector calculation for custom models to reduce discontinuities along UV seams

• Fixed problem with asset packing sometimes not updating all files in an already existing pack

• Fixed train asset packing to not turn models by 180 degrees

• Changed texture packing to always downscale non-power-of-two textures in order to save memory

• Changed importing of custom textures to treat them as having linear colour space (except albedo and emission textures which are assumed sRGB)

• Optimised automatic LOD generation for custom models

• Optimised rendering of packed models

Miscellaneous

• Fixed possible crashes at start or during simulation

• Fixed "path is empty" crashes

• Fixed problem with AI trains sometimes spawning late

• Fixed speed limit signs to load properly when the game is started with non-default working directory

• Fixed trains to spawn at the correct (shorter) starting positions where possible

Visuals

• Fixed problem with lights sometimes missing from state animations

• Fixed problem with state animations sometimes not working correctly

• Fixed normals and texture coordinates of built cross sections in some cases

• Fixed possible problem with speed limit sign normal vectors

• Fixed rendering of some scenery objects with negative scale

• Fixed problem with sleepers and fishplates bunching up in the wrong places

• Fixed alignment of auto-generated turnout sleeper texture

• Fixed wrong material being selected for autogenerated turnout sleepers

• Added rail fastenings to auto-generated turnouts. This requires the fastening model to be set up for each rail in the path type for custom track types

• Added "rnd" and "vehiclernd" animation variables

Sounds

• Fixed problem with custom sounds sometimes needing program restart before they start working

• Fixed mixing options to work correctly for non-looping sounds

• Adjusted audio mixing to get rid of panning
