In the following Quick Tip you will learn how to create a seamless wood grain effect. This is a step-by-step tutorial which is perfect for beginners to Inkscape. Let’s begin!


Step 1

Start by importing the bitmap with your wood sample into inkscape. Use either File/ Import (Control + I) or just drag and drop it into Inkscape. Embed or link it. It’s not going to stay in the file as we just need it for color reference.


Step 2

Use the colour picker (F7) to pick a few shades from the bitmap and assign them to shapes (e.g. some circles).


Step 3

Create a square and assign the base colour. This would usually be the lightest colour you picked.


Step 4

Add some lines with the straight lines too. To match them perfectly you can use a duplicate of the square, convert it to a path, break the right hand nodes and delete them. Only the left line will remain.


Step 5

Combine the shapes with the Path/ Union option (Control + +) and add more nodes to the lines


Step 6

UseSelect a row of nodes, convert the lines to curves and move them slightly to create an uneven pattern.


Step 7

The more you move the nodes the wilder the pattern will be. Change the lines’ stroke width just little from on the next and then convert the lines to paths (Path/ Stroke to Path).


Step 8

Use the colour picker and assign varying colors to the shapes.


Step 9

Use the node modifier to add more variation to the lines by adjusting the thickness of the lines.
This treatment takes some patience but it gives it a more natural feel and is worth the effort when the material is shown close up.


Step 10

There is no need to move every node as long as you achieve a less even pattern.

To reduce the contrast of the lines and blend the pattern with the background change the alpha setting of the fill colors.


Conclusion

Play around with pattern, the amount of movement in the lines, their thickness, colour and alpha setting to fine tune your material. Add gradients and shine to the texture if you don’t need the wood to be seamlessly tileable.

    more detailed explaination would be better

    @Francis – if you let me know where the problems lie I am sure I can add a more detailed text.

    Could you please explain step4 better? I can’t understand how you made all the lines fit inside the square.

      OK, I haven’t used Inkscape that much, but what I think you do is make the lines. then when you expand them they will turn into little rectangles, go and delete the nodes on the right side of these lines and delete them, now you will have just the left side of the rectangles. To make the lines fit, just draw them to be the same size.

        I did it by making the outer rectangle, breaking the lines with the tool in step4, then i duplicated and ctrl-dragged the leftmost line and deleted the rest
