Deeper Concepts
- Object Library Categories, stored in Resource Kits. The files are stored in there in the appropriate file. The ini is the parameter for the max file to get object settings.
- Resource Kit Manager to add items to a kit or modify them.
- Materials assigned in the file or allow Dynamite to assign materials with material IDs.
- Move the pivot point to the ground level, center of the vehicle.
- In the XZ plane the vehicle needs to be facing you.
- Make sure the transformation is reset to make the current one is normal, Dynamite will ignore any translations, rotations or scaling.
- Negative values make the vehicle go backwards to the direction of the shape to track.
- Exporter configuration file can be changed.
- Textures are assigned by u and v direction, u is normal to the object and v is tangential. (U-Tile, V-Tile)
- U-Tile value of -1 indicates how many times it’s repeated across the link.
- Using subassembly Type it will apply across multiple links.
- ID is the material type.
- Negative ID will flip the materials.
Optimizing Mental Ray
- Think of visualization as a photographer (Set the settings for exposure)
- May need to change the exposure control (EV) from the one Dynamite VSP uses.
- Final gather lets you get indirect illumination.
- Anti-aliasing will give better precision for viewing objects, say in Min 1 to Max 16
- Soft Shadow Precision, blur affect on shadows. Higher values for long shadows, esp. for lots of shadows.
- Glossy Reflection Precision probably isn’t needed for a infrastructure scene, probably use a smaller precision to get quicker rendering (Not all the way down).
- Glossy Refraction Precision, lower it down to get down.
- Look at slides to get the differences in render times. Shows the difference in quality and render time comparison.
- Use difference values for still images and animation.
- For animation render the final gather first and then the objects, not quite clear on this, need to look at the paper for the class.
- Daylight system can add clouds, steps in handout.
Rendered Output for Design Analysis
- Sight Checker, can see how far an object can be seen. More of a test to visually prove the design works. Not really a design tool.
Object Paint in 3ds Max Design
- Tool to add trees to a scene.
Wrap up and 3D Movie
- Can do a 3D movie, need to look on the web for links to create them.
