This lesson contains the detail view of glade creation process. The lesson is reckon on 3DStudioMax users and also is based on Grass-O-Matic plugin for 3DSMAX. The lesson consist of six parts, where you Can learn how to create: a ground surface with lichen and naked regions, illumination of bright sun day, grass of different types, flowers and stones.

Quick tutorial covering some basics of maxscript, generating and controlling objects etc. Might be useful for people wanting to get their feet wet with scripting.

Max Script Basics

Brand new tutorial in a series of Maxscript for beginners – here we introduce basic terminology and generating objects and managing them through basic mat and scripting lingo.

This series is designed to move artists into more technical subjects easily and apply them to appropriate subjects for real production.

this script converts all scene VRay materials to max’s standard material.
it keeps diffuse color and diffuse map. right now it works with multi sub-object materials if you guys found it useful .

Script

for o in geometry do
(
if classof o.material == VRayMtl do
 (

  tt = Standardmaterial ()
  tt.diffusemap = o.material.texmap_diffuse
  
tt.diffuse = o.material.diffuse
  o.material = tt
 )
if classof o.material == Multimaterial then
 for m = 1 to o.material.numsubs do
 (
  if classof o.material [m] == VRayMtl do
  (

  tt = Standardmaterial ()
  tt.diffusemap = o.material[m].texmap_diffuse
  
tt.diffuse = o.material[m].diffuse
  o.material [m] = tt
  )
 )
 
)

In 3dsmax7 Mental Ray 3.3 gained a new shader called “Ambient / Reflective Occlusion” what can this be used for? Well, traditionally within Mental Ray GI has been handled photon mapping and Final Gather. In this case a GI effect can be generated via a shader, and in this way this system opens up some flexibility in how you generate your GI.

So what does this shader do? Quite simply it shoots out rays from the pixel that is being shaded in a hemisphere based on the normal of the pixel. It then traces these rays to the scene bounds or to a fixed distance defined in the shader and if it hits a piece of geometry the ray is flagged as occluded. Mental Ray then works out the average number of rays that were occluded and uses this to work out a blend colour between the BRIGHT and DARK values setup in your shader. On the right is a diagram of a typical pixel being shaded.

In the example shown you can see that our shader has thrown out a total of 5 rays. If the BRIGHT colour were white, and the DARK colour Black, we would have two DARK rays and three LIGHT rays. So our pixel would be shaded as 40% occluded, or in other words a grey of 40% black would be used. Due to the way Monti-Carlo sampling works, 5 rays would not give us a very good average, pretty much in the same way as a sampling of 5 people in a survey would not give a very good average opinion of Mr man in the street. So for a better quality render you would expect to use 24+ samples.

The following tutorial will show the user how to Model a Hosta plant a by creating several sub models to formulate the entire composition of the plant. Additionally, applying pre-created textures using the material editor and UVW/UVW Unwrap modifiers will be covered. read more

Welcome back to my tutorials. This month we’ll move on an other side of CG, and we’ll try to find a very fast way to create a good underwater scene. So, let’s start with the 3ds max unit setup, we’ll use some physically correct features of Mental ray, so we need it. Set the scale at centimeters, and the assign renderer to Mental Ray. read more

In the past tutorial we worked on procedural shading and particles to re-create a lava flow, now we make some steps inside the lighting world trying to achieve a photorealistic interior lighting during the day, the night and in all the other hours of the day. Thia tutorial is a very fast and efficient way to produce these kind of results, it’s clear that it’s not the only way. read more

Caustics are really great light effects that you can observe in liquids, glass objects and gems. We are able to simulate this effect with 3D Studio Max perfectly. This tutorial about Caustics will work only if you enable “Mental Ray” ! (This tutorial was made in Max 8). read more

Welcome back to our tutorials. While I’m working on more interesting, (we hope), educational stuffs for you, it’s time to start a new tutorial’s lineup. This week we’ll start understanding something about fluid dynamic in a mixed pipeline using Next Limit Realflow and Autodesk 3ds max. The tutorial can be accomplished with other 3D software and Realflow. read more
