Hello,

a first test with a scene quite ... heavy.

great - what modeling software did you use to model the plants?

Nice scene :)

I think the water needs 2 B a lot darker.
Either darken the ground color or use tinted water are my sugestions for this.

Also, did you add a bumpmap to the water ?

yes, better :)

Now try this with a dark green/brown/blue texture instead of just dark brown.  Remember, in a pond like this you got algy all over the place which gives a green color.

much better  :)

this file : 250 MB

is this a normal weight?, not too heavy for Keyshot?

and more than 2 hours to render image with 12 ray bounces.

Great image. 2M polygons is nothing. Plus, render times don't depend on the size of the model, but the complexity of the scene - materials used etc.

Good improvements !!

Now if you take a smoother bump map for the water and add an environement with blue sky ... it's gonna look perfect :D

I have, I think, what you propose

?

Nice improvement ...
I'm a beginner but do you need a 12 ray bounces for a scene like this?
Title: Re: lac
Post by: guest84672 on October 11, 2011, 05:54:57 PM
Yes - because of the water. This is the beauty about realtime raytracing. Just move the ray bounce slider in realtime until you don't see any changes. That's when you know you have enough ray bounces.

Thanks for the reply Thomas ...
I know that (not that much of a beginner), I just never tried water affect ... my question should have been, does using the bump map for water require a higher ray bounces value? otherwise I get good results with no more that 6 for something similar
Sorry Antoine for doing this on your thread, I like what you've done to the scene and looking forward for the final version ...

Ok, so .. the water has a nice riple effect now, but from what I can see, the riple looks like big squares .. this makes me think that I am looking at very large pixels ... I'd try to reduce the size of the bumpmap by a lot. (Echelle U / Echelle V)  Not sure which result you'll get then though.

thank you for your comments.

I also started Keyshot.

I am used to model highly accurate models, industry type (interior design, product design, watches). I will like to learn the polyhedral model. I try to do this with Cheetah3D.

I really appreciate the software Keyshot, for its excellent ergonomics and intuitive and calm of its interface.

When I discovered for the first time, I did: phew!

Thank you to the developers.

Do not forget the user community, because without them we would advance much more slowly.
Thank very much you all.  :) :)

Philippe,

I will test your proposal with a more accurate map.

Thanks

I don't think the bump requires more bounces. Try it.  ;)

Thanks!. now with raybounces 4
