Help needed about map making.

[Talonkaine]

Well.. I was making good progress following this old tutorial CLICK HERE  .. I'm down at Post 8. However I have hit a snag once again. Having issues adding Bump Map. Looking for help.

The tutorial states: Create a new layer called “Grass Bump Map”. Fill it with rendered cloud noise again, this time setting the size and detail to the max, and selecting Turbulent.



Then it says: Hide this new layer (by clicking off the eye icon). Create a new layer called “Grass Bumps” and fill it with 50% grey.

Am I doing this part right? I simply clicked bucket fill, picked a grey color and used 50% Opacity.



Then is continues to say: Set its layer mode to overlay. It will appear to be gone now. That is how overlay works. 50% grey doesn’t change the underlying image, while darker shades darken the image and lighter shades lighten the image.

Now apply a bump map to this “Grass Bumps” layer using Filters->Map->Bump Map.


So I do what it said.  I set it to overlay. It does appear to be gone. Then I go into Bump Map......



Here I think is where the problem is. In the preview I should see my map shouldn't I? There is nothing in the preview except a transparent image. For the Bump Map drop down, I've tried both Grass Bumps and Grass Bump Map layers. Neither of them work.

The last step is: Lastly, apply the “Land Mask” channel as a layer mask like before.
I've done this as well and nothing changes. It should look something along the lines of the photo in the example....



If anyone can help guide me here, that would be awesome! Thanks.
