very nice, Martin, I echo the above....now some fishes?


Thanks Jason :) Well...honestly I was thinking about it, but couldn't find nice models.

However, I do have the Red Sea library from XFrog which contains some anemonies and see-weeds.
I tried those and the refraction destroyed their looks too much. I might try it again, but for now I'll move on to something else.

"image-map" ? How could you do that?  ;D

Nice render , Martin !

I am doing a water test image since 2 days and i can't stand the long render times. You are patient really !

Tangled-Universe

Thanks Kadri :) Yes...image-map..I know...shame on me :P
I used a fill-light setup, which is considerably faster than GI. Perhaps that's also the reason why you think it's so slow and why I'm so patient ;)

i have some fish models (in obj format) - a couple to be exact.
but their not mine, there was link to them here on the forums in a post from a few years back
i think the website is down though...

this looks really good, i especially like the sand and the little rocks/pebbles on the bottom

No reason to be ashamed for using image map shaders! When it's faster and the result is good, why not use it?

Dune

I use them all the time (as masks), but I can imagine the aim for purism. Like watercolorists hating to use opaque paint to fix their mistakes.

Oshyan

Detail 2 should be equivalent to .5 underwater I believe. You'd need 4 for detail 1 equivalence, unfortunately. Assuming at least that the terrain detail underwater responds the same as in Raytrace Everything.

But regardless it looks quite good!

Dune

Wouldn't it be possible to add a slider (+ default as it is today) to increase detail underwater?

Oshyan

Probably, yes. It's something I'd like to do, but doesn't fit into the development priorities at the moment.

Are you certain Oshyan? It's really stuck into my brain that the detail multiplier of the watertransparency is set to 0.5. I believe that actually you told me that :)
Anyhow...I'm testing now and it seems you're right as far as I can tell while rendering.
Will show the result later.

Dune

Will you be needing any fish, Martin? I've got some downloaded from this (downed?) site.

Thanks for the offer Ulco :)
At the moment I'm working on/finishing another scene and perhaps I'll render it again with even higher settings.

Very convincing work! Great! I really like those "macro" renders.
Mouthwash? We don't need no stinking mouthwash!! [MI2]

Yes Oshyan, you are right. The multiplier seems to be set at 0.25.
I'm rendering now at 3.4 detail which should be equivalent to 0.85.
After 8 hours nearly done for 60% and it's looking very good :)

Cheers,
Martin
