First, create a canvas with a custom size, execute FilterRenderingLayered Clouds, ctrl+F multiple times, the effect is as shown. Save it as a PSD format file for later use, and then execute the layered cloud filter multiple times, Save it as another PSD format file for later use. Here I named it Land Texture 1 and Land Texture 2. Duplicate this layered cloud layer and temporarily hide it for later use.
Create a new layer of fill color, with RGB values as shown in the picture
Make sure the current layer is the layer you just filled, go to FilterTextureTexture, click the small arrow, find the land texture PSD file you just saved and load it, after confirming, execute ctrl+F multiple times, observe the changes in the image, and stop when enough is enough. If it is exceeded, the highlights will appear dead white, which is unsightly.
The method for this step is the same as above. Load another land texture. After confirming, ctrl+F executes the filter multiple times to observe the changes in the image.
Add the graininess of the land to the surface: Create a new layer, use the brush toolselect brush No. 59set the foreground color to darker green and click on the new layer. Be careful not to drag the brush, otherwise you will not get the grainy effect.
Make layer style drop shadow and bevel and emboss settings
Set the layer blending mode to Overlay
