You forgot this :
For the render output choice, you can change it in the render panel by the select menu in the output section.
in F10 render panel on the left bottom
select render window
this is one i rarely use but nice to remember it is there
one wird question
to see the 2 sides is there a way to set up 2 camera and have it render at same time ?
i’m trying to find a way to see 2 sides same time if possible
or may be a trick like place in back at angle a mirror that would show the back
while tendering at same time then the front
may be this would work ?
what do you think
thanks
I think the single 2 sided face is a useless study.
I’m doing 3D for 10 years about and I never needed to do that.
Extrude your face and unwrapp it, you’ll gain time.
To give thickness to a more complex mesh, you have a script in the script window (mesh menu if I recall) that “solidify” your selection.
Unwrapping is really more important as you’ll use it always after 
For the 2 cameras render, I don’t think it’s possible :-s
agreed it’s not somethng you used often
but it’s available and many people ask this question in forum and i never seen very good answer on this
so that’s why i wanted to know more and how it works
it may be something usefull for cloth for instance with color on either side
but apart of that it’s easier to have 2 faces
it’s an available function in blender so i wanted to prepare a file tut showing how to do the setup for this so if anybody ask for it then i have a small tut ready to answer with some good examples for the next time this is ask on the forum
Thanks
I see, for clothes it may be usefull.
Anyway, clothes are not composed of only one face, so you still can train by mapping a ring of faces for example.
The front and back properties of the node geometry will be usefull this way.
You should start from scratch, model a ring of faces (from a cylinder for example) and map it the way I did in the sample file, using procedural textures for the example, easier 
Here is an example of the result and the setup
i still have to find a shape where you can see the 2 sides
my be like you said a cylinder at angle but you don’t really clearly see the 2 images
but i’ll try my idea of a mirror at angle in the bacl to see reflection
may be this will work
i’ll test that later today on tomorrow
today i got to solve a problem to read file with a script for data
have you done any scripting before ?
Thanks
If it’s not to use in blender yes, I do scripting all day long, it’s my job lol 
To load data in blender I can give you tips in python, but the structure of the data internal to blender are still mysterious to me.
no you’v heard about IES lamp in yafaray
not yet in blender but may be soon i hope
i want to read the text data in file which i began and it’s working anyway no problem up to now
now i got to show the data in blender as 2D graphic and then as a 3D graphic to show shape of the beam of light function of the IES curve datas
like an IES viewer for fixture data light specification if you eve use this before
it’s fun to do things that may be use for lighting
ok i got the first problem
i have a text line with several numbers that i need to separate and load into an array
any idea how to do that from text to array?
there is this command
line = line.strip().split() # break up each line into two segments
but how do you get more then 2 fields seperated by spaces?
happy blendering
I see, it seems fun, I wanted to make something similar about using the BGE to display realtime statistics.
Can you send me a sample of your data and I’ll write down the script to handle that.
I guess using an array is the easier solution, but it depends of the data, wich I know nothing about IES lol…
Maybe opening a new topic with this subject? Other pple may join if they know or search about that…
Just an idea
