[Award Winner] Explanation of Layer Masks in GIMP(and PS)

[jfrazierjr]

Ok. Yet another small update.

Ok, so in this episode, we will use the exact same technique to add some ground cover.

• Create a new layer
• Add a texture to the layer, in this case, I am using Grass_mud_jhd.bmp, again from the CSUAC.
• Add a layer mask set to White
• Change the layer opacity down to around 50% so you can see the lower layer
• Select the new layer mask you just created in the layers dialog
• Using a med/large brush Pencil set to black, draw out the river and parts of the bank in whatever pattern you wish to show
• Turn the opacity back to 100%
• With the layer mask still selected, Filters->Gaussian Blur around 50px, more or less to taste.

This produces something like the below image:

Now, we are starting to see something that looks like a creek bed in the wilderness. Next, we will add a tree texture with something like palm fronds.
