Could someone give me a good idea how to create lovely trees in DeleD, i had a go but ended up with something that looked like a wooden washing line! Confused

Heh. I tried this various times myself, all of them not very successful. I know how to create the trunk (?), but the rest is more difficult.

the most part of trees is the texture so it's more how good you can make or have textures than how good you can model.

here is a free example from the got3d website that you can study:

http://www.got3d.com/free/Got3d-Low-Polygon-Tree-Demo.zip

there has already been a discussion about this subject which you can find here:

EDIT: also important is if you want to create a realistic of a fantasy tree, because realistic trees are much harder to do.

Moved to 3D Modelling.

Here is what I did:

1. Create Boxes that overlap each other and form a rough circle

2. Use Union
(3. Optimize)
4. Extrude the object to this shape:

You can also rotate the vertices a little after each step of extrusion.

5. Smooth:

Like I said, it still needs branches and leaves and I don't have good texture files for that and I'm to lazy to search some!

That's a nice trick there, Fletcher.

Btw, have you tried using an extruded polyline for the trunk?

Most of the trees I've seen use a semi transperant plane with texture for the tree top. (leaves/branches)
If you tried to model every leaf, your polycount would be so high you would have a very hard time getting it into a game.

OK.
I got the texture and alphablended it. Then i put it on a rectangle and cloned the rectangle 356 times, rotating it one degree each time.
I got a white blob. Embarassed

I think you don't need to clone it that many time. 4 to 6 times should be sufficient. A white blob, you say? Seems to me you're not using a transparent texture here...

I have now tried various other things with that tree texture. Nothing works! My model is always just too transparent (more like a ghost than a tree!) Rolling Eyes

the texture I'm using is the TGA one mentioned earlier on this thread, converted to JPEG so it is compatible with DeleD Lite.

Sorry that was a bit unclear. I mean the texture inside the zip file from www.got3d.com, the tga one(converted)

did you set the texture to modulate or alphablend?
