Architectural Material Patterns - Layout

Wondering if anyone has found a good source of material PNG patterns that could expand what comes with LO? Currently, I am looking for woodgrain patterns.

Searcing past posts, I found this article (https://blog.sketchup.com/article/making-custom-patterns-layout) so, if needed I’ll just custom make them. Thought I would ask first to see if there’s any good source anyone knows about.

Thanks!

Mate, I checked out that tutorial, it’s a bit convoluted, there is no need for the photoshop steps. You can just make a texture directly in LayOut and export it as an image and use it directly.
