Start by making a single face with a tree texture applied:
(If your object program cannot display dds or other textures with transparency, you'll have to use a jpg or bmp (etc) and replace it later on)
Next, cut it down the middle, and move the two points on one side to form an L shape:
Then make a copy of that L, rotate it by 90 degrees and move it to the other side, giving you a T shape:
(The two Ls in the above image aren't touching, but that's just to make it easier to see what needs to be done. In reality they should be touching, or at least they should be very very close)
Keep copying, rotating and moving things until you have four L shapes that form a + shape:
(Note the numbers I have added. Because the real texture will have transparency, when you can see a face 1 you'll also be able to see a face 2, which helps to give the object a bit of body)
3D object faces have a front and a back. Many 3D object programs display both sides, meaning there will appear to be a mirror effect when in fact there isn't. Some programs will have an option to filter out the back faces, e.g. in 3DSimed, go to Display, Culling and select Back Face.
Many games, e.g. rFactor, will only ever show the front of a face unless the material is set to be double sided. For this method, that option should not be used.
- No mirror effect
- Only requires one tree texture
- The tree won't look the same on the other side, which can be important if a branch is meant to drape over something like a fence.
- Only really works with a + shape tree. Any more faces and the mirror effect returns.
