Hello,
I hope the more experienced Vue users can help me here.

What I'd like to do:

• create enormous waves
• place an object so that the back of the object is inside a wave, the front comes out of that wave

What I did:

• checked 'Displace water surface' in the 'Water Surface Options', so that I'm able to adjust the wave's height by hand.

• moved my object partly into one wave

My problem:

• whenever I move my object, all waves are completely re-computed and re-drawn, so my nice wave is somewhere else, and my object is either complete underwater, or not in the water anymore.

• Rendering displaced water is VERY time consuming (even in 'Preview' mode on a 4GHz dual core machine), so even several hours of trial and error doesn't gave me an acceptable result.

Any ideas what to do?

well unless you need a large expanse of water visible in render
hwy not use a terrain with a function to create waves, thus lower memory requirements as you can erase pieces of the terrian not visible in render which will reduce reosurces needed, and being a terrian, should be fixxed? :)

odd that the water is changing though

Thanks for the suggestion, that's a thing I always wanted to try anyway, so I think it's a good time for it NOW :)

Found the reason: in the displacement function there's a time node (probably for animations).
Disconnect this node and the wave stays static. Easy fix.

Ah, usually it's something simple but unexpected like that, good to know! ;)
