simlab composer lite .... awesome

Thanks for the answer and sorry for my late one My first need is for a simple stucture let say a "corrugated" cardbord composition .

I never go above 220,220,220 for whites.(sometimes even 205,205,205 when the scene is brightly lit in exteriors). When the white material has a lot of reflection and/or refraction (glass) assigned, you especially need to be careful not to use high RGB's, because you risk to break the law of conservation of energy. Reflecting/refracting more light than you put in is physically impossible and will always look wrong.

Thanks every one ...

hi! it is really wondeful to see what sketchup community is doing to improve it even with "little" rubies like this one..and for free...A GREEEEEEEEEEEEEEAT THANKS.

okay; this aspect seems to have been drastically imporved with 7.1 , it's a great move on the right direction... i've tested some orbiting moving with a large model, and everything was good... working on it will probably confirm this... good work Google team. keep enhancing this aspect of Sketchup...

Are you wanting to write a ruby script to do this or to use a ruby script to do this?

...thanks for the quick answers.
