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! thumbsup
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.
Mental Ray Displacement (with file download!!!!) 0111

Start with a Mental ray material shader.
This is pretty much easy to follow.
These are the material settings.
Mental Ray Displacement (with file download!!!!) Mat013


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!
Mental Ray Displacement (with file download!!!!) Dgs10

Second, on the Extended Shaders under Displacement, I've used a Height Map Displacement.
Mental Ray Displacement (with file download!!!!) Mat110

For the Height Map I've used a Cellular map. The numbers here are variable.
Just tweak them to your preference.
Mental Ray Displacement (with file download!!!!) Mat210

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

Mental Ray Displacement (with file download!!!!) Render10

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.

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. Smile

Hope this helps.

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. Smile

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. Smile

@ 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.

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.
