Hi,

I didn't find any infos about carpet on the forum. Do you have some advice. to have a "volumetric" carpet

Seriously, any advice about the shader (to simulate good fibers) ?

Will Kray support diplacement ( microdisplacement) in a futur version ?

thanks

Carpet and fur is a problem at the moment in Kray. We will have to wait for the next release to have some solution for this one...

Hi! Will microdisplacement in the kray in the future or so and remains a problem?

We must wait for displacement and fur generator (this is on the list ) now we can use instance (this is not ideal tool but better then nothing...)

For carpets, grass and such the instances are quite good solution...

kray instance ideally suited to grass, but I need to create a relief on the object using the displacement map, such as in the figure are made columns.

Without micropolysh displacement is hard to do this.
You can try to do this whith subpatch mesh and displacement map but the polygon count increase considerablely

this is bad example but yes for this you need displacement map. You can tray and play with dpont's relief map node. maybe you can get away for not so closeup shots.

Can you show a simple example?

Hi Ruslan,

I posted this on another forum regarding Relief mapping, its in Italian, but you can see how the node is arranged and you can see how a 2 poly wall creates a pretty good result, it is a tad slower than regular bump map though, and the shadows it casts are hard shadows (good for sunlit exteriors particularly)

Hope that helps

** edit **

here I posted a quick kray anim as well : http://www.lwita.com/vb/showpost.php?p= ... stcount=17
so you can see the shadows are relative to the light/camera angle, which is loads better than regular bump mapping

looks very good!
We can download it? I saw info does`t work on x64....

Hi _mats_! Thank you very much!

Hi Johny,

The page to download the DPKit is this: http://pagesperso-orange.fr/dpont/plugi ... des_2.html

On the left column look for Relief Map. I read it's description and I didn't saw any info saying it will not work on x64. In fact the node exists on the x64 version of the DPKit.
