In this tutorial, I will show you how to make a tileable texture in Affinity Photo and use them to texture objects in Blender for your project.
Setup
I will be using a photo that I downloaded from Pexels
I make a new 1K document (1024 x 1024) in Affinity Photo
Under the view menu, I open the guides manager
I click on the new guide icon and add a horizontal and vertical guide
Image
Under the file menu I will choose place and drag out my image – making sure to have an even number of planks
With the layer selected, I use CTRL + J and duplicate the layer twice
I select the bottom layer and I lock it and hide it
I select the top layer and under the filters menu, I choose the distort menu and the affine option
This option will allow me to move, scale, and rotate the document by percentages – it is the same as the offset option in Photoshop
I change the X and Y offset by 50% each
I move the layer down (so it is the middle layer)
I select the new top layer
I select the ellipse tool and holding down SHIFT + CTRL, I draw out an ellipse from the center of the document
I add a layer effect to this ellipse
I will add a gaussian blur and change the radius to 30px
I right-click on the ellipse and choose “mask to below”
I now have a tileable texture that I can export as a PNG
Blender
In Blender, I add a plane and scale it up by 5
I split the view port and open the shader editor
I make a new material, drag in my wood texture, and connect it to the principled shader
With the node wrangler installed, I select the wood texture node and use CTRL + T to add a mapping and texture coordinate node
I then change the scale to 2
I can now see the texture tiling
