Tilesets

^Home

Tilesets make it easier for you to define brushes that allow you to paint 2D tiles onto your tile systems. You can define a tileset from an atlas texture which includes the artwork for a number of uniformly sized tiles.

Each tileset is represented with an asset which:

• Associates the tileset with its atlas texture and material.

• Defines the way in which tiles are packed.

• Contains tileset brushes that are used when painting tiles.

• Manages pre-generated mesh assets for non-procedural tiles.

Once you have defined your tileset you can create a tileset brush for each of the tiles that you would like to be able to paint with. Tileset brushes can then be used with the provided editor tools or dynamically using the Runtime API.

Remember - If you previously used version 1.x of this extension then you may have used atlas brushes for painting 2D tiles. These have been replaced with tilesets brushes which can be used procedurally or non-procedurally. Previously atlas brushes were only able to paint tiles non-procedurally.

• Tileset Designer
  Tilesets can be modified using the designer window which can be accessed via the brush palette. Tileset brushes can be created using this interface.

Child Topics:

• Edge Correction
  Bleeding will usually occur at the edges of tiles due to texture filtering and/or mip-mapping. Two popular ways to reduce the visibility of such artifacts is to either inset UV coordinates by half a texel, or to add borders around the edges of each tile in your atlas.

• Procedural and Non Procedural Tiles
  Tiles that are painted using a tileset can be presented in one of two ways; procedurally or non-procedurally. The performance of painting and erasing procedural tiles tends to be better than that of non-procedural tiles whereas non-procedural tiles can offer greater flexibility.

• Working with Tilesets
  Tilesets are created using the Create Brush / Tileset window which can then be managed using the tileset designer. Tileset brushes can then be created using the tileset designer.

• Tileset Brushes
  Two-dimensional tiles are painted from tilesets using tileset brushes. Each tileset brush is able to paint a specific tile from the associated tileset.

• Autotile Tilesets
  When designing tiles for things like walls, paths and platforms the artist will often need to produce edge pieces and corner pieces. The design process becomes inherently more complicated when inner joins are needed due to the quantity of permutations that are introduced. Autotiles provide an easier way for artists to create such tilesets.
