● Prototyping must be done fast
● Prototyping should give an overview of the production tools needed
● Prototyping should give an overview of the possible market (playable)

Enhancements to go further● Logic Bricks
– A great tool for fast development
– Become hard to read when the complexity increases
– SOLUTION : implementing the ability to turn the bricks into a full python scripting (Python Event Handling – this point is actually being discussed...)
Intro > What > How > BLENDER in a commercial context > End

Enhancements to go further● Custom tools implementation (python scripting)
– Python exposure of some functionnalities (For example the NODAL features)
– Blender UI access from python
– SOLUTION : it seems to be part of Blender 2.5 new API

Enhancements to go further● Project oriented development
– Lack of global project overview (multi-blend files projects)
– Source control integration inside blender
– SOLUTION : ability to turn the folders view into a project management window that takes a root folder as the root of the project.

Enhancements to go further● Lighting and shadows performances
– During our developments we had to :● Reduce a lot the number of lights in huge scenes
● Lower shading complexity for the materials
– SOLUTION : Rendering optimization by reducing the scope of action of the lights.
Reducing the scope to the area displayed around the camera focus, or whatever... (+ « defferred shading » in Blender ?)

Enhancements to go further● Protecting the IP (intellectual Property)
– Actually BGE doesn't allow to export a project into a full binary distribution : Graphics ressources and linked .blend files stay editable.
– So we provided a video to show our work
– SOLUTION : To extend the binarization applyied to the main .blend file to the others (the linked ones) and to encrypt external datas.

Enhancements to go further● Some other minor issues
– Recurrent loss of relative paths for highly linked huge projects
– Loading time very long at files opening (but quite good « ingame ») and crashes sometimes
– Characters physics behaviour very hard to manage
– SOLUTIONS : We are looking forward to using Blender 2.5 which should fix some of those problems.

BLENDER in a commercial context
A larger use of Blender in the game industry ?● Development of bridges with the principals game
engines (even when they're not Open Source)– Requires actors to be more involved in collaborations
(more intensive use of standard formats...)
● Deploying a more complete support– Personalized support together with Blender
specialists/ingeneers for companies who need it
– This could be both more people using Blender and more revenues for the Blender Foundation

CONCLUSION
Our experience with Blender ● Blender is a great tool and it takes an important
place into our production pipeline● Thanks to it, we reached our goal : producing and
showing our first playable Demo● With some advanced features and services, it
could become a software of choice for a complete game development pipeline (it is already the only one that combines creation of both the world and the game)
Intro > What > How > BLENDER in a commercial context > END
CONCLUSION
FINALLY● Even if we are testing it under GraphicAll.org, we
are looking forward to having access to the 2.5 stable release !!
● We see in Blender a stable and reliable tool– Big and skilled community– Fast development

CONCLUSION
More informations about our BGE experience● The video of our first game prototype on our web
site : http://klakos.com● Some extras for BGE adepts
– A « Hack'n Slash » template V0.1
– A complete tutorial addressing « terrain splatting » methodes we used (nodal way)
– A tutorial showing a sample of RT objects multi-texturing with nodes and vertex painting
