Use 3D studio max to create and apply texture to terrain.

Create first ‘layer’ of terrain texture:

1. select the terrain model, to have texture applied to it

2. Press ‘M’ to open to material editor.

3. Click Assign Material to Selection button

4. Click Show Map in Viewport button

Double click Bitmap type

6. Double click Bitmap

Select treebark jpeg

Click Maps section

1. Click Maps section, to open up Maps section, in case the Maps section is still closed

Click Opacity Map button

2. Click Opacity map button

Double click Gradient Map

3. Double-click Gradient Ramp

note: if we use the opacity map, black means completely transparent, white means completely opaque, and grey means partially transparent

Click on gradient ramp to add gradient flag

4. Click on the gradient ramp, between first and middle flag, to add another gradient flag there

Select Edit Properties

5. Right-click on this flag, and select Edit Properties

Change to whiter color

6. Click color bar, and change to a color closer to white

7. Click Close button

8. Close flag properties dialog box

9. Right-click on what was originally the middle flag, and select Edit Properties

10. Click color bar, and change to a color closer to black

13. click and drag this marker to the right

Select Fractal option

14. Under noise section, select Fractal option

Change Fractal settings

15. Change amount to 1, and levels to 1

note: fractal option is good to create randomisation of gradient, so it will spots which have black or white color will look more natural => resulting areas of transparency will also correspondingly look more natural

Create second ‘layer’ of terrain texture:

1. Right-click left viewport to select it

Shift and move to copy object

2. Shift and move current object (the terrain model) downwards, to create a copy

Change Z position of copied object

3. Change value of Z position, so difference in Z position, between original object and copied object, is small, eg. if original object’s Z position is 0, then copied object’s Z position should be -1

4. Open material editor

Select different material slot

5. Select another material slot

6. Click Assign material to selection button

7. Click Show Map in Viewport
