Just wanted to show you guys how ridiculously well KeyShot 4 is handling translucent plastics (polyamides, acetals...).
In both images the part (a fixing clip) has the exact same material applied.
In the second image I placed small spheres with area lights underneath the clip. Finally we can simulate LED's behind those milky plastics! ;)
Dries
Variation of the same clip.
Also, I used the filletting feature of KS4 to slightly soften hard edges.
Dries
That's a very nice Nylon material - care to share your settings for that? I'd find it very useful indeed.
Thanks
This is the equivalent KS3 scene and material. Exact same settings, size etc.
By putting both KS3 and KS4 images next to eachother, it's quite noticeable how much the translucent material has improved: no more black contour edges, better diffusion of light...
Dries
fantastic!
merci, very interresting.
Well if this doesn't sell KS4, I don't know what will.
Awesome stuff Dries & KS-team !
Shame I can't realy join the b..
*grrr-forum-grumbl*
So as I was saying:
... the beta testing. Darn company IT-rules ... (I would need the IT-guy to come over to install every single beta update. It's hard enough getting him to install the KS3 updates already)
Very nice indeed! Thanks for the KSP file too, Dries. :)
Beautiful... I would be grateful if you could share the KS4 scene - to get an idea of light placement and intensity etc :)
Cheers

KS4 scene has exactly the same lighting. :)
Same HDRI, same environment settings, no pins, no local lights.
Dries
pssst .. he probably meant those area lights ;)

Dooh... :o
:D, yeah, Phillipe hit the nail directly on the head... ;)
Much appreciated Dries

very nice pics....and yes the new translucent shader is just amazing :)
Thanks Dries!
Very nice pics~~！！！
Great work.
Great example of the new translucent materials in Keyshot 4.
Thanks for sharing.
It's a keeper... :)
Tim
Thanks for all the kind words! :)
Here you have another shot. This time with a warm IES spot light from the top and a cold spherical area light in front of the 'ECO' mark.
Dries
More of a studio approach for lighting this clip. :)
There is very little EV lighting in this scene (brightness 0,135). There are 4 area light panels in this scene.
Also a little animation of the original scene settings...
Dries
VERY NICE !!!
A few shots of another very specific clip. ;)
Dries
Superb!!!i love those material render!unfortunately i cant try because i have not ks4
Do you have to change the material if you render it on a white table top? Or will that material work well in a assembly rendering?

The material is quite good as it is. :)
I applied it to a little assembly I grabbed from grabcad.
The white material is exactly the same as the the clips I posted earlier. No material settings changed. The assembly has the same scale as the clips (original size in mm).
note: I'm not to sure that these PA parts would actually work on a steam engine in real life... ;D
Dries
Very nice!
Thanks!
Here's another shot with a bit more spunk.
Dries
Sweet
thats all very beautiful and nice, but translucency in ks4 has still bugs, and the new point and ies lights are worthless when it comes to shadows... i hope there will be an update soon....
i think you can only appreciate all that with a nice 16core machine ;-)
cheers

Can you be more specific about the "bugs" with the translucent material?

It's true that translucent materials take longer to resolve when rendering with area lights than rendering with just an HDRI. I thinks that's normal behavior.
Also, the images above were rendered on a 6 core machine (3930K) and still rendered pretty fast.

iam a really huge fan of keyshot, especially because it made it easy for me as a 3d newbie to get great results in a short period of time. iam in design industry since the early 80s mainly graphicdesign, ui and photoshop composing and stuff, i even did software dev. eons ago for kai krause, so i know quite a lot when it comes to betas, updates, et cetera. when i get a software update, after some time i decide for myself if its a "good" update or a bad one. sure keyshot 4 has a lot of totally cool new features, but that gets me nowhere if i cant use my 3d mouse like i could before and if the software crashes about 2 times an hour. so at the moment keyshot4 is quite unusable for me, apart from the fact that if you want to use the new features everything takes x10 as long. also features like the ies light that i really really have waited for eagerly, turned out to be useless for serious stuff because of the hard shadows, i really hope that the next minor update puts keyshot where it was... usability wise... :-)
attached you find the translucency bug, its just a ball with translucent material in startup hdri...
That look really good

I do get that faceted look too when applying my PA material on the sphere OBJ in the KeyShot resources folder.
However, I don't get it on any other geometry that I create myself.
Maybe there's an issue with the sphere model, when applying specific materials?
Dries
You will need to increase the samples for the material.
If there are crashes, then please report them to support@luxion.com.
Very Nice!
