Hi!
I think I am on a newer version of Blender so it may be causing me some issues. I could also be making some mistakes. My displacement modifier is changing the mesh in a more subtle manner than shown in the tutorial despite having the exact same settings (like a very fine detailed granular wood.) If I mess with the settings of the modifier, specifically change the coordinates to Global and increase the Strength to .2, I am able to achieve the same result. However, I am not sure if having these settings will cause me problems down the line.

I should've kept going through the tutorial before posting.. he did address what I was asking about :D
