Why Blender?

• Lightweight

• Complete

• Powerful

• Free

We use Blender for all our 3D

Workflow• Modeling

• Setup Scene with background image loaded into the 3d view for modeling reference• Create cube, loop cut in the center, delete half, Instance duplicate the half cube and flip along the axis.• Model character• Merge the two halves together.• Create UV layouts and assign textures to the model

• Rigging• Create basic skeleton to skin to the model to (this is the skeleton that gets exported for the game)• Duplicate basic skeleton and add in IK controllers where needed and any other controllers that may be

needed• Add Location and Rotation constraints to basic skeleton to follow the joints of the IK skeleton.• Create vertex groups with basic skin skeleton to the model• Put skin skeleton on another layer so It doesn't get in the way

• Animation• Create actions using the Rig• Bake In the IK to the actions• Remove all unneeded channels from the action set• Delete IK based Actions• Delete IK rig• Remove all the constraints from the skin skeleton

Blender 2.4

• Usable real-time IK even on slower machines

• Cleaner, more usable

• Demonstrates how much can be changed

Very important release

benteye Development Environment*

• built to ease the pain of cross-platform Java

• drag and drop design

• support for multiple file formats

• library of pre-made algorithms, or add your own

*planned features only

M3G

• Over a year of development and testing

• complete implementation of features including proper Skinned Meshes and exact textures

• complete compatibility with all major vendors and manufacturers

• performance tuning based on target device

• very efficient export for minimal filesizes

core API*

• GUI

• Controllers

• Loading/unloading

• Global variables, objects, and media

• Scene changing

• Data classes

• Replay

• Persistent Storage*planned features only

benteye Workflow*

• export from authoring environment

• import into benteye Development Environment

• create all the controllers

• create layout for levels using imported files

• link all controllers to all their scene partners

• export the application

*planned features only

Why Blender?

• Blender allows developers to stay competitive

• Ideal testing and development environment

• Fully scriptable

• Has all of the basic animation features needed to create mobile games with impact.

Why not Blender?

• Developers are trained with other systems

• Re-compilation required to make changes

Ease of implementation

Why not Blender?

• Finesse required during modeling

• More advanced methods of control for Armatures

• Removal of Python requirement for linking

Ease of use

Looking Forward• Beyond Blender 2.4

• JSR-239

• OpenGL ES 2.0

• Brew, c/c++

• Next Generation Cell Phones with hardware acceleration

• An installed user base of over 25% in six months among all mobile phone users

Bight Interactive contributions

• Python Scripts

• 3D formats

• benteye Development Environment, free for non-commercial use

• Mobile specific branches of Blender

Requests

• Beta testers

• Game developers, hobby or professional

Recap

• Blender has many strengths, and is complete solution for any 3D developer

• Hindrances lie in some workflow portions of Blender

• The mobile market is a great venue for lightweight development, the greatest strength of Blender
