Useable or crap ?

That depends. How many faces?

Use able or crap, as in does it look realistic,

But every mesh has about 12000 faces, and you have to multiply that by about 40 to get the total amount.
But I did a stress test on the Plasma engine a while ago with 1.500.000 faces without any problems.
So why does the amount of faces matter, except for the fact that an object should not have more then around 14000 ?
And it runs fine on my systems ... ;)

I wouldn't call it crap but that is way too many faces to be usable on low end systems (unless there is not much else in your age). It does look great though.

X-forms are generally the industry-standard for realtime grass as it stands. That grass is probably supposed to be used for rendering...

Indeed X-forms are more used, but I wanted to see if Plasma could handle it. And it seems it does !

Do you have more pics, perhaps a first person view of the grass. Looks pretty good. I think this is a good example of how we can test Plasma to see how far we can take it on high-end computers that can handle more advanced graphics.

Just a friendly reminder that System Requirements for URU where:

* Supported OS: Windows® 98SE/2000/ME/XP (only)
* Processor: 800 MHz Pentium® III or AMD Athlon™ or better
* RAM: 256 MB RAM or more
* Video Card: 32 MB DirectX® 9.0-compliant video card (see supported list*)
* Sound Card: DirectX 9.0-compliant audio card
* DirectX Version: DirectX 9.0b (included on disc)
* CD-ROM: 4x or faster
* Hard Drive Space: 2.5 GB free hard disk space
* Peripherals Supported: Mouse, Keyboard
* Display: 800x600 16-bit display

That why most of us try to make ages which are adlest playable on low end computers.

I've spent some time trying to research this X-Form grass and couldn't come up with anything. Could someone post a link to more information? Thanks!

Yes where .... Uru released in 2003... and thats 8 years ago.
I think we can say that computer development did not stay still and that the average computer is better then in 2003.
I have had this discussion before, and I'll say the same as I did then. I'm going to create things I want to make, and
who ever wants to play it is welcome to ! But I'm not going to minimize what I'm able to do in ages because then not
everyone could be able to play it. So for the people with computers that are from 2003, I'm sorry but you probably won't
be able to run this on your system.

For even more realistic texture it's possible to render bump and specular maps into the grass texture, and maybe add a small reflection
that makes it look wet or damp.
