Marmoset has published a new Hexels guide by Mark Knight to creating seamless pixel art textures.
To start, I used Pixel Layers on the ‘Squares’ template and enlarged my canvas size to 275×150. This allows for plenty of room to move shapes around.
Creating the seamless ‘fizzy drink’ texture.
I created a solid 32×32 square to form the background of the tile. The next step was to draw a series of circles on a new pixel layer to represent bubbles. The bubbles are offset from the tile for the following demonstration.
I tested the tileability of the pattern by double-clicking the ‘bubbles’ layer and ticking the ‘Wrapped’ box in the Layer properties window. This shows how the image repeats and where components needed to be repositioned to avoid seams.
I moved some areas horizontally and vertically to their corresponding positions.
