Making a room...basic but importiant questions

[Arnold Grove]

When doing interiors (in my case..no outside light source) do you guys like to make a simple box and reverse the normals?

 

(when i select my polys and flip normals.....I still see both sides)

 

 

OR

 

do you use the loft command...which i learned in the Smith book...but when i do this....my floor area shrinks because of the thickness of the wall from my loft ref shape.

 

I had it 2 feet think so I could take the roof off and make other renders of the floor plan from above. Using a box flipped wont look right as it will give me flat walls..I need thickness to these for these floor plan renders.

 

But using the loft I loose the floor area which screws up all my other geometry because the walls contacted in from the shape, it shrinks the room in. So thats a problem with things on the wall...lights, etc

 

I always try to find these answers before i ask but Im sort of lost. thanks

I like using the first method. or using poly modelling to create only the absolutely necessary faces. To see trought the "inverted" faces, right with the object selected, go to properties and check "backface cull".

Polymodeling also, select element, flip. voilá!

check this out, i know it'll help a lot.

right click your box, goto object propertys and make sure backface cull is ticked.

in the future to stop this happening, goto customise, preferences, viewport tab, and tick backface cull on creation.

found it..thanks guys....im not sure why bu the object display properties was greyed out...so I had to hit that little option button 'by layer'

 

these ies lights are increadable...you can waste hours of time just having fun....but another question...

 

 

when i use the 750 watt bulb...i just dont get the nice terminator on the wall...Im using 200 and 400 watt bubs...w/ gi on i loose that nice arc of light...the whole point of ies is to recreate real light...but do you guys use ies to get that look on the wall and use fill as well?

 

thanks for all the help...ive learned tons in the last few days from the push!

Some time ago there was a thread of the accuracy of the calculation of the GI from vray vs the acuracy of a ray tracer or something like that. some one ws looking for an explanation on whether it was acceptable or not, academically talking. The case, is that the GI from vray is not necesarly perfectly acurate. What you are doing i re creating that effect you are looking for. You have some photometers you could use to measure the decay of your lights.
