3D Studio Max Add Texture to Terrain
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

5. Click Diffuse Map button

6. Double click Bitmap

7. Select appropriate map to use, eg. TREEBARK.JPG
8. Click Go to parent button
Change opacity of first ‘layer’ of terrain:

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

2. Click Opacity map button

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

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

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

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
11. Click Close button
12. Close flag properties dialog box
13. click and drag this marker to the right

14. Under noise section, select Fractal option

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

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

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

5. Select another material slot
6. Click Assign material to selection button
7. Click Show Map in Viewport
8. Click Diffuse Map button
9. Double click Bitmap
10. Select appropriate map to use, eg. GRASS2.JPG
11. Click Go to parent button
