Atlas - terrain editor

As long-time Unity users we have been working on a new terrain editor that overcomes the shortcomings of a purely brushed vs purely generated workflow.

With Atlas you will be able to...

• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ Generate stamps using your favorite world engine and put your terrain together in real time.
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ Refine the way stamps blend with each other ‎‏‏by brushing their opacity.
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ Discover interesting terrain features as you transform, blend, morph stamps into place.

• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‎Build road networks, rivers and cliffs with the ‏‏‎Spline tool \o/
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‎Make your terrain fit with structural features and gameplay areas.
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‎Change your design at any time in a non destructive way!
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‎‎Use Unity's prefab workflow and hierarchy to stay ‏‏‎on top of things as your level grows‎ into complexity.

Bring out the artist inside yourself and build unique, feature rich environments with ease.

You can immediately start building levels, the package contains 8 terrain textures, 58 pre built stamps and has sample scenes for every render pipeline.

Atlas is lightweight yet powerfull and stays within it's scope of terrain editing, it's designed to be a team player, non-invasive and compatible.

Features

• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ Simple and powerful workflow
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ Multi-terrain support
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ Compatible with all render pipelines, VR/Mobile.
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ No impact on runtime performance or memory
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ Adaptive editor performance
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎59 pre-built stamps for you to get started
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎Stamps can be edited at any time
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎Import stamps from terrain generators such as:‎‎‏‏‎

[GAEA,World Machine,World Creator]

• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎Export height, global normal map, global color‎‎‏‏‎ map and 16 Splatmaps
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎Splatmap control
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎Scattering of trees, foliage and objects
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎Splines that can make connected road‎‎‏‏‎ networks and rivers
•      Supports terrain Holes
• ‎‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎automatically add a meshes to your Splines
• ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎ Scale references (get a sense of scale as you create your world)
•      stamp brushing to make them blend and fit
•      automatically strip stamp data from your build to optimize size and memory

Atlas 1.04 is a finished product that has gone through extensive testing, big changes are not expected so that your experience remains consistent and reliable.

Essential bug fixes will be resolved and our support team is happily available to assist you almost every day of the week.

Release Notes

[1.0.4]

[fixed] warning about variables in scale references class not being used outside the editor

[fixed] issue where scattering would fail if one of the elements in the list is null

[fixed] issue where being asked to override terrain happens for every terrain in the scene

[fixed] issue where splat maps only apply up to 8 layers instead of 16

[fixed] issue where target layer drop down gets stuck when there is a missing terrain layer assigned to the terrain

[fixed] issue where the draw state of trees and vegetation sets to true each time we exit preview mode

[fixed] issue where draw instanced state sets to true each time we exit preview mode

[fixed] issue where preview mode is not disabled when entering player mode

[fixed] issue where terrain layers that dont exist are rendered anyways and result in black spots on the terrain

[fixed] issue where spline does not draw when it has 2 points

[fixed] issue where edge erase for spline stamps would tile along the spline

[fixed] issue where spline operations like smoothing do not support undo

[fixed] issue where changing brush size and opacity had reverted controls

[added] feature to split splines meshes into grid chunks

[added] editor tool to enter/exit preview mode quickly without having to select the preview volume

[added] project setting to strip stamps from build and play mode, reducing run time memory and build size

[added] features to alter the mask from height data and edge techniques like blob and square edge fading

[1.0.3]

[Added] Editor message asking to proceed when Atlas alters your terrain for the first time.

[1.0.2]

Fixes

[Fixed] issue where terrain layers that share the same name woudn't be selectable.

[Fixed] issue where closed splines didnt close properly.

[Fixed] issue where the spline mesh setting called "maxDistanceBetweenPoints" gave errors when smaller or equal to 0.

[Fixed] issue where the spline mesh setting called "width segments" gave errors when set smaller than 4.

[Fixed] issue where the spline setting called "width" gave unwanted results when set to a negative number.

[Fixed] issue where the preview volume spammed errors when GI is enabled.

[Fixed] issue where dropping spline to floor would not repaint the scene view.

[Fixed] issue where gizmo icons would re-install whenever the project recompiles.

Features

[Added] event that triggers whenever the terrain re-renders which can be hooked up to other tools.

[Added] scale references to give you a sense of scale on your terrain, choose between Human, Tree, Bush, House.

[Added] a performance boost option on the preview volume named "terrain update mode" choose between HeightAndLOD, Height, None.

[Added] warning where a texture lower than 16bit is assigned when 16bit is expected.

[Added] actions on the preview volume to subscribe to when we enter or stop editing.

Changes

Reduced overall gizmo drawing for a cleaner experience.

The high resolution square now takes into account terrain height and positions itself better.

Spline to mesh now updates the mesh instead of creating a new game object each time.

Spline to mesh now updates live as you alter the export settings.

Spline to mesh has a quick acces button for removing the mesh.

Exporting textures or editing masks does no longer create a new folder in your main Assets folder.

Rewrote the SplineUtils class featuring easier to use API.

Changed some icon names to follow the conventional naming.

[1.0.1]
