i'm a bit disapointed in your choice of carpet, sir.

please reconsider your taste in rendering real carpet.

perhaps then we may have a real discussion.

good day, sir.

Arghh your hurting my precious retinas...



Heres the problem, this nice little render, sl18, uses 23 gigs of ram Its not the carpet we can see that uses the ram, its the carpet out of shot. Something to bear in mind.. Rule of thumb should be, pretess for foreground, on-the-fly for mid-ground, R2 for distant stuff?

[Polyxo]

Thanks for that comparison!

Also instancing of pretesselated small tiles of carpet might be an option one might try out?
I wonder how that performed with your blue carpet.

My personal focus here was to figure out if there are cases where on the fly really was superior for studio-shots of products.
I don't ever have to render actual carpets.
It seems that your tests confirm my own findings - that pretess performs on par with it or even better on small detail, while running a lot faster.

For Product-Work one never needs 100 squaremeter of anything, stuff should fit into ram, but there's of course the wait for subdivision to happen.
Maybe some sort of selective mesh-caching which only invalidates an already exported mesh when the user changes its subdivision could help?

Thanks now my retinas burn.

Yeah, that carpet reminds me of what comes right after this scene in Fear and Loathing in Las Vegas.

[Mihai]

That's a good way to make wide gamut monitors explode....

Why not just use a good normal map for these carpets? Displacement seems overkill.

[bograt]

That carpet reminds of the smell of popcorn, cigarettes, and feeling sick

[eric nixon]

I am using a strong normal map (ditched the bump map) but you NEED disp to get the look of whispy backlit hairs..

This blue one just is the same mxm with a new map.


This persian one has smaller hairs and more of them and lower roughness - more metallic.


And this one for Rusty, its tileable for max headache.


Impressed how 2.7 handles oversaturated maps with thinsss and additive layers, this material is breaking a few rules

hmmmmm........ i'm going to need a refractive buddha on flat surface for approval.

[eric nixon]

ok?

[dmeyer]

ok?

It's beautiful!

Remind me of this website.

Finally did one at real scale about 1.8 x2.5 m with an alpha'd edge, about 8gigs ram, 1hr render.

Bravo!

Oh God, my Eizo's hurt - this thread was hijacked to good effect :D

But, still, these rather flattish carpet fabrics remind me of British bus and train seat fabrics, pre-privatisation as well as post-privatisation :D

We trainspotters still suffer severe retina injuries from colour schemes such as http://www.flickr.com/photos/ee507/6146836767/

That's the big advantage of living in Spain or Portugal - nice stone floors, no carpets needed...
