about my tree

Recommended Posts

Hi, i want to ask a single question. Will it be too high poly for a tree with 6396 polygon? See the images below. It is the tree model i made using 3ds max. I planned to include the tree into my game project.

It depends how much else will be in the scene. Although 6000 polys for a tree does seem a bit high when a lot of games use that amount for humans etc.

hmm not sure yet...
if the map is a forest... should be many

above is the test forest rendered in 3ds max:

anyone here knows normally a tree model has how many polygon?

And... below is the test terrain rendered in 3ds max:

Simply, yes, its too many. You want to aim for nosmore than 1000 polies/tree (for comparison, a character is usually between 3000-4000). The best trees I've seen so far have been in Elder Scrolls IV: Oblivion. Each cluster of leaves is its own billboard, and it looks fantastic. Look at how they do it.
If you still want to use that model, get rid of all of your smaller branches, and reduce the amount of sides on your canopies and the tree itself. A wireframe shot would help, but you can cut your polies in half by using half the amount of sides.

Well, you can also make a bit good looking trees with 30 polys...

This trees i have done, use only 30polys and a 128*128map per tree...

You can render the tree from different angles, then paste the renders as textures onto a simpler model to make it more workable as a game object.

If you do want to make a forest of those its possible but I suggest you use some sort of adaptive degradation, to do this you simply find some way to reduce the number of polygons and make multiple models staring with your best one and ending with the most poly reduced one, then make it choose a model to draw depending on the distance from the camera, so when you look at one close to you it looks good but one off in the distance is a chopped up mess but hope the player cant tell from said distance

i've been able to make a pine tree model with 12 polys, you just have to learn to be creative with your alpha textures and polygons. as for the type of tree you're trying to make, it could be done with about 400-800 polys porbably, i just don't see how you got 6396... try to optimize the cylinders a bit more i guess. another trick is to make the branches out of 1-3 planes with a well thoughtout/placed branch texture and use that for your branches. the techniques for you to use kind of vary with the models use and viewing angle.
