Chrysler believes that it’s offering of this 3D Educational Toolkit to the public at no charge to be the first of its kind in the industry. This gesture is intended to provide an impetus for 3D Visualization classes everywhere and as a means for their instructors and students to hone their skills without the requirement of an additional vehicle data fee. In this way, Chrysler hopes to see its data provide the material for quick growth of 3D Visualization Education to match this rapidly expanding industry. As a leader in automotive visualization Chrysler realizes the importance of developing the creative talent that can work with their data. It is in their interest to have a steady supply of artists that can do the increasing amounts of CG imagery and animation for their expanding marketing needs. What is There to Download? – 3D Vehicle Geometry back to Introduction There are three complete vehicle data sets: 2007 Jeep Wrangler Rubicon 2-door, 2008 Chrysler Sebring Convertible Limited, and 2007 Dodge Viper SRT10 Coupe. Each data set is broken down into smaller Autodesk Maya .mb scene files that contain elements such as exterior, interior, hard top, soft top, undercarriage, and Mopar accessories. For example, data set for 2007 Jeep Wrangler Rubicon 2-door will contain the following files: 2dr_Wrangler_Rubicon_Exterior_hrdTop_mb.mb 2007_2dr_Wrangler_RepresentativeUndercarriage.mb 2007_Wrangler_Rubicon_Interior_Maya.mb 2007_Jeep_Wrangler_A7_Seats_Maya.mb 2007_2dr_Wrangler_Mopar_Parts.mb 2007_Wrangler_Hard_Top_Updates_MAYA.mb 2007_JK72_SoftTop_wDoors.mb What is There to Download? – Backplates and Domes back to Introduction Each vehicle set also includes 2D-backplates and HDRI domes. These high dynamic range domes and high resolution backplate images are provided for you to practice creating photorealistic renderings using environmental reflections and image based lighting. These are just suggestions, so feel free to experiment using your own backplates and domes. For example, backgrounds and domes for 2008 Chrysler Sebring Convertible Limited will contain the following files: What is There to Download? – Reference Materials back to Introduction About Chrysler Vehicles: Realize that vehicle classes such as Wrangler, Viper and Sebring each have several trim levels to them. For instance you can get a Jeep Wrangler as either a Base model, Sport, Sahara, or Rubicon. These are considered the different trim levels of a Jeep Wrangler. A vehicle can be configured in a lot of different ways: you can choose the exterior paint color, the interior color, type of seats, whether it is equipped with Navigation system, or Mopar accessories.

These exist as images, text documents, .PDF, power point, and spreadsheets files. Much of the reference material is used to determined how to make the render product correct. We highly recommend you practice using reference materials as it is an essential part of the job of Automotive Visualization artist. Reference Materials for 2007 Jeep Wrangler Rubicon 2-door will include the following files: Color Charts 07 JK Sahara & Rubicon (Cloth opt.) - Khaki (J3).doc 07 JK Sahara & Rubicon (Cloth std.) - Dk.Slate Gray-Med Slate Gray (DD).doc 2007 JK Color Compatibility Chart.doc 2007 JK Interior Color & Trim Summary.doc Component Graphics Clusters Logos-Badges Radios Grain Chart 2007 JK Wrangler Grain Chart.pps Material Samples Exterior Colors Grains Interior Colors Interior Fabrics Soft Top Fabrics Quarter Scales 2007 JK72 Wrangler E5 First Row Bucket Cloth.pdf 2007 JK72 Wrangler E5 Second Row Bench Cloth.pdf Wheel Charts 2007 JK Wrangler Wheel Chart.xls Reference Images 01-12-06 2007 JK72 Wrangler Media Site Photos 04-04-06 2007 JK72 Wrangler Rear Seats Restraints 06-02-06 2007 JK72 Wrangler Undercarriage 07-01-05 2007 JK72 Wrangler Rubicon Hard-Soft Tops Tires TT7 LT255-75R17 BSW Off Road BFGoodrich Mud Terrain.jpg What is There to Download? – Reference Materials back to Introduction Color Charts The color charts indicate what combinations of trims have what kind of color availability. In the Trim summary chart example below you will notice that all the Jeep Wrangler trims come in either color code DD or JJ. DD refers to a two tone interior color scheme of Dark Slate Gray and Med Slate Gray. While JJ refers to a Two tone color scheme of Dark Khaki and Medium Khaki. Color Compatibility Chart: This chart refers to what exterior paint colors are available on each trim level. Interior Color breakup charts: These are charts that specify the color that parts of interior geometry should be for a particular interior color code for a particular trim. Normally the parts in the 3d geometry are assigned materials shaders for one available interior trim color. Example Interior color breakup file: 07 JK Sahara & Rubicon (Cloth std.) - Dk.Slate Gray-Med Slate Gray (DD).doc What is There to Download? – Reference Materials back to Introduction Component Graphics Included are images that can be used to texture the radio navigation screen, to texture the instrument panel cluster if the cluster wasn't included as geometry, and related logos and badging that may not have been included as geometry. Grain Chart These indicate what type of bump texture gets applied to the various interior parts. Some bump textures have names such as Millennium or Machine Weave, CPM501, CPM526, CPM493. Below are examples of grain chart for What is There to Download? – Reference Materials back to Introduction Material Samples Material Samples are used to create texture maps for vehicle interior, and include the following categories of materials: • Convertible Top Fabrics: scans of fabrics used for convertible top • Exterior Colors: scans of exterior paint samples and digital multi-angle readings of LAB, CMYK and RGB values of exterior paint • Grains: scans or photographs of interior plastic grain textures • Interior Colors: digital representations of interior colors based on RGB values • Interior Fabrics: scans of cloth, leather, vinyl, carpet and flooring materials • Interior Finishes: decorative finishes used on interior Instrument Panel, Door trim, etc. Convertible Top Fabrics: Interior Colors: Exterior Colors: Interior Fabrics: Grains: Interior Finishes: What is There to Download? – Reference Materials back to Introduction Quarter Scales These PDF documents indicate how the seats should be constructed. They provide information about seat code, material application, and general seat shape. Quarter scales serve as a good addition to reference photography of seats. Wheel Chart Wheel charts are useful to identify which wheels are available on a particular trim and which tire gets put onto the wheel. What is There to Download? – Reference Materials back to Introduction Reference Photography Extremely useful are the photographic images of the Exterior, Interior and mechanicals that can be used to develop photorealistic material shaders, identify geometry not provided within the geometry data such as cargo nets. One note of caution is that the reference photography is not always 100% product correct or shot with interior parts that have had grain applied to the parts. Tire Photography Photography of the tires can be used to created texture maps to provide detail to the tire's sidewall. Chrysler Educational Toolkit - System Requirements and Technical Tips back to Introduction System Requirements: To assemble a full vehicle requires a large amount of memory. A computer with a 64bit operating system and 4GB is recommended. Computers with less RAM can still work with the data: it might be that only selected parts are loaded and rendered then assembled in an image layers or as composited animation layers. Software: Autodesk Maya 8 or current version of the software is required to be able to open and translate the geometry files. Other software packages may be used for final rendering or animation. Please see the list of recommended software packages on our web site, as well as links to student versions of those software packages, available to be downloaded on your machine. Technical Tips: There are variety of 3D Computer Graphics programs capable of creating automotive CG imagery. To use the Chrysler .mb files in other 3D programs requires the files be translated to a format that the software can read. To translate the files to other formats you will need a Autodesk Maya 8 or current version. Maya is capable of translating the .mb files into a variety of formats such as .FBX and .obj. Many companies working with the data use additional software to successfully translate the files to other formats. These would include Deep Exploration from Right Hemisphere, and Polytrans from Okino.
