Hi there...

Here is the result of a Ice-tutorial I tried out...
Used Fprime so the cubes does not deform.

Here is the link to the tut:

Very nice indeed. Pity I don't have LW8 to do the tutorial :(

it looks just a little too blue, water does have a blue tint to it but it isnt noticable at that small amount, it looks good overal though

Yeah you might want to tweak your thickness gradient.

BTW if you want them to deform, add the Fprime displacement plugin after your deformers, and fprime will pick it up.

Thanks everyone!!

Adrian...I think this works with 7,5! Or maybe it doesn`t

Sidetrak...yeah, it`s to blue. I made it to dark. Will tweak a little.

Dodgy...i will try that now! I saved the sceen. :)

It would be nice to put some melting ice-water nearby the cubes. :rolleyes:

Update: Now it looks better I think...not so much blue...and the deform is there.
Fprime is great...this render took 7 min. (quality 6). With F9, it would take 40min.

what water are you drinking???? Water has no color.

yes it really does, we went to a nuclear power plant for school and there was a giant stainless steel vat full of water and it was blue, my teacher asked if it was painted that way and the guide said that it was just so deep that the faint tint of water was showing through making it look blue...dont know if that justifies but its where i heard it

I was playing with the tute and and imagine my suprise when my image looks very similar to yours! I do have a question though. In the two attached images the only difference is one has caustics (so I can see some pretty little light-thingys) and one does not. the one with caustics looses the nice shadows -- they all come out just dark. Again, the only difference in these images is the addition of causitcs to one of the lights. Is this normal or is my newbie brain just missing something?

They all look good from a distance, but have that destinctive procedural look which I don't think holds up very well on closeups.

Water is blue, its selective absorption of reds and vibrational transitions.
Why is water blue? (http://www.dartmouth.edu/~etrnsfer/water.htm)
Also note that Ice does not absorb as much as liquid water does.

Also, it would be nice to have a little puddle forming below the ice ;)

Hi there,

this is my personal interpretation of ice cubes ....I have modified something ...let e know what you think about...

cheers..

Looks good...maybe a little to much reflections.
Which gradient did you modified?

I send you a surface of ice cube in a file .srf compressed.
I hope you like my modifications

Its looking nice, but wouldn't the corners of the ice cube melt faster than the sides?
