how can I make water that looks convincing and doesent use alot of render time?
I have looked all over the internet and these forums and I cannot find anything that helps me.
help me
Can you be more specific? Do you mean water as in the surface of a sea or lake, or sitting in a glass, or flowing out of a container? Ice?
ahh yes, sorry
like a lake or pond or a sea that dissipears into the horizon
that kind of thing
I trying to become adept at building landscapes and so-forth
Here is a render of some water I made using procedural textures. It’s animatable, not photorealistic by any means (no spray, e.g.) but could work in a brief shot.
If it’s what you have in mind, I can post a .blend.

I know you didn’t ask yet, but here are the blends anyway so I don’t lose the links. These are highly simplified versions of the excellent seas created by Cog (www.cogfilms.com). Check out his tutorials. I employed layered textures mapped to Normal and used IPO’s to animate the Z offset. As in any scene, lighting is very important.

that looks great but I’m going to need to be able to have it in an animation
however I would like it if you would post a .blend and some info on how you made it, it would be a great addition to my knowelege database.
any other ideas?
Try animating the blends I posted. On my Wintel machine (3.2 GHz P4, 1Gb) rendering each 800x600 frame at 100% size takes about 1.3 sec (no OSA or raytracing). YMMV.
and all these are is a plane with a few procedural textures that have been animated on the z offset, using the IPO editor?
what is the pourpous of the AguaAlpha texture?
Yes, it’s just a garden variety 4 vertex plane. I have a Stucci txture mapped to Nor in the first channel. Second channel is a common “glow” effect employing spherical Blend affecting Ref, spec, and Alpha along Z normals.
The second AguaAlpha texture simulates reflections off the wave crests. Turn it off to see how much you lose without it.
Does it work for you?
I think it might

I now have another question.
how would I make a waterfall (I have been trying to get this to work for soooo long)

ROUBAL apparently described a nice waterfall in this thread; unfortunately his old link is dead. Perhaps if you contacted him he could give more detail on the blend.

Again, your approach will depend on your needs. You could probably get away with an animated texture or even .avi for a very long shot. Up close it would look horrible (I imagine those illuminated scenes with “moving” water you see in kiosks at shopping malls, ugh).
Heres a picture of how water done with that technique looks with a background picture to reflect off of it. Looks pretty nice. I made this in about 5 minutes, so it’s fairly easy. On my 2.66 P4 it rendered in about 10 seconds.

You’re welcome. I look forward to seeing what you can do with this technique.
data65: Not bad for 5 min quick and dirty work. Is this actually using the technique from my .blends?
I made an ocean from a nice tutorial.
Here’s the tutorial I used: http://www.pekaro.de/blender/water/water_tutorial.html

No not from your blends, but using the same technique. I did add some ray mirror to it.
so I think I’m forgetting something it just doesn’t look the same as yours, the light dosent reflect the same way.
