High Density, High FPS grass :)

Well, I have been away working and researching... the idea i got from the large amounts of grass they use in Battlefeild Vietnam, so atempted a recreation. They do have their flaws which I am trying to iron out, but for now, i think they have some potential :) Here is my little test map (ignore the mist layers, that was a project that didnt go quite as well):

(for an FPS scale, I get 40 on remagen, lol)

Tell me what ya think :wink:

EDIT: I'll post it when its done :)

EDIT2: Oh, and it is really nice to run around in, looks quite natural :wink:

Looks pretty sweet :) Can we see the same map without the grass to get an FPS comparison?

Sure, have to wait till monday though :wink:

Here is a rough FPS walkthrough:

(Avg. Remagen FPS = 40)

Looking at the large patch of grass from about... 500 GU (game units) = 80/90
Looking at the large patch of grass from about 100 GU = 60
In the grass = 40

But I agree, a grassless map would make a good comparison to measure the impact :)

I hope I can get this crazy grass working, it really does look quite cool ingame 8-)

I'll post it if and when I can get rid of the errors that are frequently popping up :?

If I can't get rid of them... I'll post it anyway :)

Colour and Transparency can be set through shader - making another colour version of the same grass is dead easy - make a new shader linked to the same image, but with different RGB amounts set :)

And welcome to .map buddy :wink:

Hey thanks for the welcome. Just started mapping a little bit ago and this seems like one of the best place to learn things. The scripting is a bit hard, but I think im learning.

It is for sure :wink:

Any questions, no matter how foolish, don't hesitate to ask; or use the search button :D

I had to turn my brightness all the way up to see something, but hey, it certainly looks great then :D

If you want you could add

alphaGen dot -0.2 2.0

or something along those lines to the shader to prevent the grass from looking flat from above :)

Nice work m8 :wink:

looks good but the pic quality is bad, but i can see your pattern for the grass in the map. can't see much grass.

What does alphaGen dot -0.2 2.0 do?
