maybe try to use a few cones on top of eachother, and work with textures if it is a background object.
if you are going to be closer try using the curve to tree script, but i dont know how well that’ll turn out (i personally hate it).
if not maybe try to model a few branches and use particle effects to look like the spiky leaves they have.
hope this gave you some ideas.
If you create the tree stem and branches im pretty sure that a simple particle system could result in a realistic tree. There is a good tutorial on blenderguru.com that will teach you to make a tree that im sure you can use for your project. I’m still a blender noob so I’m not 100% sure that what I told you is accurate but I still hope it helps.
well i saw this blenderguru tut
it’s well made but still using the old 2.49 tree to curve
which is supposed to be low poly but can easoly get over 200 000 vertices
which is not quit low poly anymore!
but there might a way by using some particules system instancing
but not certain how to do this !
there is also A new script being made by Ecrivain which might do the trick
but not yet completed
i hope this one keep the low poly goal here ! LOL
