Architecture<br />

Lighting the scene<br />

Balancing the interior and exterior<br />

First, we need<br />

09 a global diffuse light<br />

(sky light). That was achieved<br />

by simply adding a map to our<br />

environmental override in the V-<br />

Ray render window. It’s a simple<br />

bitmap I downloaded from<br />

CGtextures.com. Note that this<br />

is not a light source, so it doesn’t<br />

produce any shadows.<br />

Now put in the main light source that<br />

10 stands in for our sky here. It is going to be<br />

a VRayPlane positioned above our scene facing<br />

down and tilted a bit towards the camera.<br />

Attached to it, there is a VRaySky which is put<br />

in the Reflection/Refraction override.<br />

12 hours<br />

render time<br />

Resolution:<br />

2,250 x 3,000<br />

Modelling<br />

the scene<br />

As you can see, there are<br />

no complicated models<br />

in the scene (except for<br />

the trees which are not<br />

modelled by me). I am<br />

really bad at this and<br />

everything you see in<br />

this image is made from<br />

primitives with the<br />

fewest and most basic<br />

of tools. Even the leaves<br />

on the ground were<br />

scattered manually<br />

instead of using the<br />

Scatter tool. I always<br />

want to get over this p<strong>art</strong><br />

as soon as possible. This<br />

is probably one of the<br />

main reasons I stick to<br />

architectural renders: the<br />

geometry is always the<br />

least complicated, as<br />

opposed to a car or<br />

anything more organic.<br />

The three lamps on the ceiling will provide the main light in the room.<br />

11 For these, I used VRaySpheres as lightbulbs. We need some supporting light<br />

sources from each side. I used small VRaySpheres with a Radius of 0.1 metres. I also<br />

needed three VRayPlanes to light the ceiling around the wooden walls on the left.<br />

And here is the result of the lighting. It’s a bit bright, but that’s okay since<br />

12 the override material is white so, once it’s all textured up, it will be balanced<br />

out. I p<strong>art</strong>icularly love the night shots because of this ambivalent lighting: the blueish<br />

outside colours complementing the warm colours of the interior and vice versa.<br />

This shot of the house from another angle provides an alternative<br />

13 perspective and is a good example of the balance between the two colours<br />

– the warm and the cold – and how well they can work together.<br />
