Mental Ray Displacement (with file download!!!!)

Hindi kasing tindi ng mga tutorials ni Sir Edosayla but nonetheless useful for those wanting to learn mental ray.

This not different from Jeff Patton's displacement technique. Mad props to Jeff!
This is applicable for carpets and grass. But this time we'll be making a simple grass displacement.

Here in my example is a simple plane.
I've added a tessellate modifier.


Start with a Mental ray material shader.
This is pretty much easy to follow.
These are the material settings.



First, on the Basic Shaders I've used a DGS Material on the Surface slot.
And on the Diffuse slot of DGS apply the grass material.
Make sure that Glossy Highlights is black, unless you want glossy grass/carpet!


Second, on the Extended Shaders under Displacement, I've used a Height Map Displacement.


For the Height Map I've used a Cellular map. The numbers here are variable.
Just tweak them to your preference.


Lastly, Under the Renderer tab, on the Shadows & Displacement rollout:



1. Edge Length - The higher the amount the faster the render but then you lose

the finer details.

2. Max Displace - The height set in here should be higher than what you

specified in the Maximum height in your displacement to avoid errors.

3. Max Subdivision - I've used a small amount here because I have tessellated my plane already.

4. Smoothing - Uncheck it. We don't want smooth grass.

And here is the outcome.

ano kaba sir .. galing nga eh.. keep posting sir sa mga tutorials ..

Hehehe, basta ba ikaw ay laging may pino-post din na mental ray tutorials!

tnx sa tutorial sir!godbless!

wow!!! galing nito! mukhang completo na tayo sa mental ray ah. thanks bro!

sir, isa tong kapaki-pakinabang na kaalaman!!! salamt!!

galing tnx

Walang problema. Check mo yung mga video tutorials series ni sir Erick a.k.a edosayla. Marami kang matututunan.

nice tnx po

baka pwede po step by step po, ano po size nung plane? or kung ano man ung ginamitan nyo ng tessellate modifier, di kasi same ng result sakin eh, pls? thanks

mga bosing eto result ko patulong nmn pano, cnunod ko step by step di ko alam bakit magkaiba tyo output, pm nalang po or reply dito maraming salamat po

Baka pwede mo i-post yung settings na ginamit mo dyan sa render mo. Marami kasing factors kung bakit hindi umubra sa iyo.

Gaya nung material. Sa blank na material slot click and use DGS na material. This step is essential.

Yung plane ang nilagyan ng tessellate modifier. Step by step na yun. Try mo ulitin yung procedure, taking note na wala ka lalampasan sa mga steps.

Keep practicing. Makukuha mo rin yan.

Hope this helps.

ung size ba ng plane sir hindi factor? naka 3000x3000 ung unit na ginamit ko jan eh, baka mshado maliit ung diplacement?

to create a scene its very important na gumamit ka ng real world scale para ma achieve mo ang tamang settings ... try to do it on a scaled dimension para ma check mo kung ok or hindi

Spot-on sir Eric! Tumpak! Working with real-world scale helps. Hindi uubra ng tama ang settings kung hindi tama ang scaling mo sa scene. You will have to tweak until kailanganin mong gumamit ng mga "old-school" tricks para ma-achieve mo, which is may I say long method.

Heto mas maganda basahin. Mas detalyado ang mga instructions. Hope this helps. http://3dsmaxrendering.blogspot.com/2008/05/ultimate-mental-ray-grass-shader.html

Ok, for those finding this little instructional a little bit crazy to follow here is the Max file for download. It's in 3dsmax 2009 version. You can do whatever you want with it. You can scrutinize and dissect it and get the hang of setting up displacement for yourself.
Have fun with it and enjoy.

galing sir thanks

thanks for sharing sir. newbie here.. explore muna ako para madami pa matutunan..

salamat sir, malaking tulong 'to.

wow! cool galing sir... salamat sa dagdag ka alaman sir.......

@ all: Walang anuman mga bro. Palawakin niyo pa kaalaman ninyo. Baka pwede nyo i-upload mga trial renders ninyo sa displacement dito at madiscuss natin kung anu-ano pang pwedeng baguhin o i-tweak sa settings para mas mapadali pa ang pagrerender ng scene na merong displacement.

thanks master logik more please ...

Kulit din ni sir Eric. Alam mo na to di ba?

hehehe isa pa master ha ... hehehe sabi na nga thanks e hehehe hintay lng natin mga kapatid marami pang tinatago yan si master logik

May mabilis na setup para sa displacement ng mental ray. Sa loob ng Arch & Design, sa pinakailalim makikita yung Mental ray Connection, sa Extended Shaders, i-click yung lock icon para magamit ang Displacement map.

Piliin ang 3D displacement(3dsmax).
Ilagay ang displacement (bitmap) image sa Extrusion map.
Pihitin ayon sa kagustuhang taas at lakas gamit ang Displacement Length at Extrusion Strength


Enjoy!
