vray grass

If you are using v-ray and don't use the VRayDisplacmentMod, then you should switch to mental ray! I use both, but v-ray is very powerful at performing geometric displacement, and is superb at creating organic objects; even grass looks good with displacement. Mental ray is good at displacing small polygons of geometry, where V-ray is good at displacing detail over large polygons. For this reason v-ray 1.50 sp1 is much more successful at creating grass for very large sites; a big plus!

The shader is simply just a VRayMat, with a grass map in the diffuse slot. Then I applied the VRayDisplacementMod modifier to the object. I instanced the image map from the shader into the displacement modifier.




VRayDisplacementMod settings:
• For something like grass it’s very important to use 2D mapping rather 3D mapping.
• I instanced the image map from the shader into the Texmap.
• I changed the amount to 4” to have taller grass blades.
• I increased the resolution to 2048 for better quality.

BillBoard Generator 2.62

A simple script that facilitates the creation of vertical planes for use with trees/people images billboards.

1.Select a diffuse map (tree/person image)

2. Select a matching Alpha map of the same map. or press the lock icon if you use a TGA/TIFF image with an embedded Alpha channel.

3. you may resize the plane to a desired height or width (great for specific people heights).

4. Press the Generate! button.

Once done the script will place a vertical plane with the tree or person in 0,0,0 .

You may change some parameters both before and after the billboard is created.

If you check the Random checkbox - each time you press the Generate! button - a billboard of slightly different dimensions will be created. You can also determine the max/min offsets.

The defaults for the billboard name and its material can be modified only prior to its creation.

You can Pick Point in Viewport < to specify the exact location of a newly created billboard. If you already have one selected - picking a point will move it to that new point. You may reset it to the world zero point by pressing the Reset button.

If you need more than one instance of this billboard - use the scatter engine. Enable it , Type the number of duplicates and define a rectangular area where the billboards will be generated. Scatter uses the Random function if it is enabled.

You may also modify the Shadows casting and reception and visibility parameters of the billboards.

The Orientation command will orient the selected billboard to an object - preferably a camera.

To download the script , go ahead Mr.Nir sullam's website who has kindly given us permission to put this on our blog

particle flow for hedges

tutorial for making hedges

This tutorial was written by Mr. Nir Sullam from Orvatsel , Israel. I thank him since he has given permission to reproduce his tutorial in this blog

http://www.orvatsel.com/max/hedges/
For our tutorial we need to have (or prepare) a leaf to use for our foliage. (you can use these 2 images)



You can create your leaf plane by either creating a plane and then create a material to apply to it OR you can use my free Billboard Generator to do this automatically.



You will get this: (you can change the size of the leaf with the Height spinner)




Create a BOX with a L: 200 units W: 50 & H: 80



Under the Create Panel > Geometry > Particle Systems Create a PARRAY object.


This is what you should see:




Select the PARRAY object.
- Under the Basic Parameters Rollout:

1. In Object Based Emitter - Press the Pick Object button and click on the BOX object
2. In Particle Formation - Select Over Entire Surface.
3. In Viewport Display - Set the Percentage of Particles to 10% or less - setting a higher value may halt your system.

- Under the Particle Generation Rollout:

1. In Particle Quantity - set to Use Rate and set the number to 1000 or more - this actually sets the number of cloned leaves over the entire object - the more the better but do not use too much if your system is not too powerfull.
2. In Particle Timing - set Emot start to -300 and Emit Stop to 30 and Life to arount 50-100.
3. In Particle Size - set the size to your needs. it may depend on various parameters.

- Under the Particle type Rollout:

1. In Particle Types - Set to Instanced Geometry.
2. In Instancing Parameters - Press the Pick Object button and click on the LEAF object
3. In Material Mapping and Source - set to Instanced Geometry and press the Get Material from: button.

- Under the Rotation and Collision Rollout:

1. In Speed Spin Controls - Set Phase to 90 degrees.

Basically - That is All !

This is how it looks:



Select the BOX object and make it unrederable (object properties)



Now render.

Here are two examples: one with a lower rate (around 300) and another with 1000 - obviously denser but more time consuming.





An awesome thing you can use this process for is to create irregular shapes and apply it to any object you create:
