Hey guys I saw the thread about trees and tried to make one by my self.
I also did some grass.
Here it is:
C&c always welcome, thanks

The grass looks nice... I like the tree roots. Most people just use the 'candle in a birthday cake' technique.. and dont really show it rooted..
Maybe the leaves look a little sparse? More leaves!

Itís really coming along! I would definitely go through and add some vertex color, especially to the leaves. Add some dark color to the center of the planes and give them some depth. I would also say mix up the texture a bit for the leaves so they are not all the same shade of green.
Love the roots as well, good attention to detail on that.

i think the green color of the leaves look a bit artificial and plastic. grass looks great! :)

Dont have the grasse planes be cut like that. have them fade out to transparent towards the bootom too, at...20% the imagem.
this way they'll look decent in any ground.
also maybe the treetrunk is a little too thick.

Like KazuyaMochu has said, the grass looks too cut on th bottom. I think you have to use the same technic you use for the top of the grass's planes.
The trunk looks great but too contrast. Maybe if you decrease just a little bit the saturation it could looks better.

Yay ! Thanks for your great critics everyone.

You are completely right with the green of the leaves ;)
I will change that.

I already importet the grass to the unreal engine and it looks good but
I will give it a try and fade it out on the bottom. ;)

i wouldnt blend out the alpha of the grass at the bottom, if you use edit normal on the grass, which it looks like you have, or is it 100% illumination, then you can simply keep the bottom of the grass a consistent shade of green and put it on a ground that is the same shade. if the normals of the grass are pointing in the same direction as the ground then you shouldnt have a prob with sharp lines where they intersect.
but the grass texture needs to fade out towards side as its an obrupt edge at mo.
05-23-2006, 03:02 PM
Currently its 100% illumination because I dont know how to set normals the right way. ;)
In this update the sides of the grass are not sharp anymore, also saw that problem.
Now, here is the update:
- worked on the grass a bit more (alpha, more contrast)
- added more color variation to the leaves
The trees triangles are (with leaves): 450 tris
The whole scene is: 1440 tirs
C&c always welcome

Grass looks alot better! But i would say you still need more leaves. Other than that its great.

any chance in making a tutorial? cuz it looks awesome and i would love to be able to do that
05-25-2006, 10:18 PM
Nice that you like it.
I've never made a tutorial before ... Do you need a tutorial about texturing or about modeling ?
05-26-2006, 02:48 AM
more the texturing but i can't seem to get tree modelling down for low poly... but mostly the unwrap and texturing for it cuz I'm doing my senior thesis and those trees would fit perfectly

The grass looks really nice man. Do you mind sharing the flats for that?
Awesome modeling and texturing, my only crit (which had been said many times) is that there aren't enough leaves.
06-07-2006, 09:15 PM
yes the leaves ... :scream: i just like how they look now ;)
Here is the flats of the grass.

I really like your grass texture. So many games, even "realistic" ones, have green grass; yours has a lot of whites and browns, i love it! nice job!
06-07-2006, 10:21 PM
Oh mighty maker of tasty looking grass...your grass is looking very nice! I agree that the tree needs more leaves....alot more leaves. But the leaves that are on the almost bald tree so far look good once you added some more colors.
Man that grass is just real nice to look at :)

This is a great example of grass/trees. I am currently working on a tree myself and can learn a lot from it. Personally I hope you buff out the tree leaves a bit though, to make the tree appear fuller. Recently I was studying the trees in Resident Evil 4 and found the ones with leaves appear to use sprite based leaves! They rotate to face the viewer no matter the angle... it doesn't work perfectly but works quite well.
And SHEPEIRO (member.php?u=183235) if you could explain how to make the grass planes' normals face the same direction as the ground plane (which is likely more than 90 degrees different), please do!

Hmm, can't see any of the pics besides the wireframe.
jfalconer, if you're using 3ds Max this can be done with the Edit Normals modifier. I have some pics here, plus the tech issues I had to deal with...

Thx Eric, I use Maya so I will have to look into it, the results speak for themselves.
06-10-2006, 12:55 AM
Thats wierd .... the wire is hosted by an other side ... are there any other people who cant see the pics ?
06-12-2006, 02:14 PM
OK, I can see them now. When I first saw this post, I drilled into your website URL and found the pics, but I just couldn't find the texture image.
I'd suggest filling in the black area with green. Often the black will cause a bit of a halo along the edges. Some examples here: http://www.ypoart.com/tutorials/Alpha-about.htm
