    Cool R2-D2 Free 3D Blender Model Conversion Ver 1-0

    Original 3D model created by: InnovationByLayers (Jason McMains) in Autodesk Inventor Assembly (.iam) format.

    Conversion of model and new Blender Cycles renderer materials by PixelOz (David Guzmán).

    This is an R2-D2 model conversion to Blender 2.6* format from an original model that was created by 3D modeler Jason McMains that he placed in the public domain. It has close to the 1 million triangles mark cause it was originally a parametric solid Autodesk Inventor model and I did a high poly res conversion so the model looked high quality. Still it is not a super detailed, rounded edged model, it is not as efficient as it could be due to the algorithmic tessellation in the conversion from a solid model to a mesh model for Blender but overall it is a very good quality model and it renders fairly fast in Cycles.

    Anyway its curved surfaces look very smooth even in close ups due to the high poly mesh conversion. I was looking for a good quality R2-D2 3D model to convert it to Blender format but most of the free ones out there were very loose and had many, many errors like missing parts, many, many things out of the correct proportions and shapes, etc. and the good ones were very expensive. This particular free model created by Jason looked very good to me cause I know how R2-D2 looks pretty well because I have seen hundreds if not thousands of pictures of him in the web and I have the blueprints from the R2-D2 Builders Club which I believe are the best out there on the Internet.

    I placed the model against blueprints views from the front, side and the top and the model matches them very closely. I believe that this model is of a quality that is equivalent to some commercial models out there and I decided to use it for the conversion. I spend about a week in the process fixing the triangles and everything (the standard conversion process) and giving it Cycles renderer materials cause it was time for me to start to use the new renderer more fully and in more photo-realistic renderings it is way faster than the older one anyway.

    I did a few small improvements to the model in Blender (added a few missing details like the optional restraining bolt, etc.). There is far more information about what I did in the accompanying PDF documents including info on how to easily change the robot to the 2 legs position and there are many more details about the model overall and its Blender materials. I hope that you enjoy this model.

    Note: To generate a render that looks exactly like the one I did you need the same environment texture that I used and it is available for free in Deviantart. The accompanying PDF documents say were to get the texture and how to place it again in the file (a very simple process). If you just click render without giving the environment a reflection texture the render will come out looking pinkish cause it is the default color that Blender uses again when it doesn't find the assigned studio033.exr HDRI reflection texture in the textures folder.

    Address in Deviantart to the free texture pack (HDRi Pack 3) that contains the needed studio033.exr environment reflection texture created by Deviantart member zbyg:

    1 million triangles, wow. And Blender handled it, cool. Your version one images look great - what was the render time?

    I have handled scenes with many more triangles in Blender. I have handled and rendered scenes with close to the 3 million triangles, I think I can handle and render up to about 4 million but above that it kinda starts to get problematic in my PC. The render time for each one was about 1 1/2 hours at 2048 x 2048 resolution at 600 samples. With 800 samples it takes about 2 hours at that same res but it rendered smooth enough for me for the purpose at 600. Hardware is Intel i7 920 2.66Ghz, 6GB DDR3 1.3 Ghz Mem triple channel. Computed with the CPU with 7 threads (I leave the 8th free to be able to do other things with the PC while it renders).
