after read more closer, it's not so easy because to can use swap, we must do 3 more full hires renders almost noisefree.

I thought ,one time you made your render , you can change unlimited times your material without make additionnal renders , but it's not... so: One original render + 3 others..., it make many hours and steps just to can change one material...

Yes, thats a "little" detail.

where did you read that?

They are not 'extra' renders in the sense that you don't need the 'original' render anymore. They render more or less at the same pace the original render would. Only, the white/black ones are slightly faster. But if you want to simplify things completely, you could say that using SWAP starts making sense the very moment you need to:

1- either produce 3 or more versions of the original image (3 because you need to render 3 times to get to SWAP)
2- or you want to test and try and prototype until you find the look/s that you want, trying a progressive number of variants.

If all you need are 2 variants, then you wouldn't need SWAP as rendering the scene twice would be enough.

Just like the quote on my sig.... this feature is something where I see myself bending over

Hes just saying when it makes sense to have Swap...not that you need to render it 3 times

We've been asked not to quote anything from the Fry site so just go look at the Swap product overview. It tells the proper information.

plummet, it need to render 3 times the original render ; 1 "white render" kind of occlusion, one black render, and one mirror render to cover all possibility for an opaque material.

Take a look on the swap brochure , it's explain...

Did not know that, but as a just said in FryRender's forum, my apologizes.

.

Sorry, but you must render three times to use Swap, and as far as I know you must specify before the renders begin which object you want to change.

[alexxx_95]

you are right jespi:
3 renders, choose before what material will be swapped and just opaque material, no dielectric, no sss, no caustic

[jespi]

Thanks for confirm Alex.

It just tells the renderer to pay special attention to those 3 things on the object you are changing the materials on.

It's like choosing a z-depth and alpha map to be generated at the same time as the render.

It is only rendered once....

*frowns*

[jespi]

No its not. You can read from my quote. You have to render three times.

[pluMmet]

Ahhh I see.. you guys are right

[alexxx_95]

maybe for the "black" render it's like a channel render(quick), but for the white render and the mirror render , it's not the same.

[pluMmet]

The color render is once but the 3 layer renders are separate.

I wonder if they take as long as a normal render?
