hello @Rainshine

Using this style (mike Schley overland) here its my process:

1 I position my volcano on the map using the sheet Symbol

2 I create the sheet SYMBOLS TREES BACK (as <<< to draw attention) and position it above (below) the Sheet symbols and below (above) the sheet symbols back.

3 select the tree you want and select the new sheet - SYMBOLS TREES BACK

4 place any tree icon where you want

5 - refresh

Tree images on this sheet automatically go behind images on the SYMBOLS sheet. Note the error in the lower left corner where the trunk of the palm tree appears undesirably behind the volcano image.

Then you can select the icon and delete it (more work) or hide it in the next step.

6 - Now go back to the original sheet of the SYMBOLS TREES program and work from there.

This is where I usually "hide imperfections" in images that were poorly placed on the sheet at the back. In this case I cover the root of the palm tree with more palm trees, but it could be a hill, a city, etc.

7 - If you want to add a "pasture" effect you can still create a SYMBOLS TREES GRASS sheet and place it under all symbols sheets

8 - select the Scrub vegetation and make sure you are working on the new sheet symbols trees grass (sometimes the program "forces" you to go to another sheet and you have to select the sheet you want again).

And place the Scrub where you want the effect.

9 - refresh

For the floor textures, I did not use default terrain but rather the skirmish vegetation and terrain - maximizing them a lot.

Now that I found the ruins in the isometric, I was able to complete my cursed village 😎
