which way is usualy use to create water.
1.use transparence material + texture.
2.use texture with alpha channel.
i think the first one is faster.
i didn''t konw the diffent between using material or using texture.
Yann L hosted a lecture on the #Lecture channel on AfterNET about Realistic Water Rendering a while back. It''s a good read. Here is the log.

You can create water by use texture with alpha channel.
This is a easy way and can make high FPS

thx,but why not use material,
I didn''t know when shoule i use material,
Use material will get low performance??

Because use texture with alpha channel only define four vectex.
use transparence material + texture must need define N vectex.

YES,it is animated.

Can''t get the links to work...
would really like to see the water in action...
i have done an animated water in my game, just 5 frames and setTexture when changing but its not that exciting looking

You can download it late,the web server might idle now.
Could you upload the screenshot of your water-effect? THX
