I used 3 lights in my scene. The 1st light (and also main light) is a Spot Light; I used 'Far Attenuation' with 'Inverse Square Decay because I needed real looking light, falling into dark space (dark space inside my room). Also this is a very helpful option, if you want to have a physically correct falling-off of your shadows.
The 2nd light - the volume-light-emitter - is another Spot Light. Also, I selected the [Use Light Smp Range], because I use Attenuation and deacays. And I wanted to have my volume-light's light also fall-off like the main light. This is how my Volume Light looks when I just started setting volume properties (1).
But in the end, my dusty volume light, began to look right (2).
The 3rd light is an 'Omni Light'. This light is inside room, does not cast any shadows and has an almost black colour. This kind of Black-coloured light is often named 'Light-sucker'. These lights create a 'moody' character in my scenes. I like this effect :)
Big hails to "Total Textures" once again. I dont have to look around chasing good looking walls with my digi-camera. No more walking into restricted areas, just to take one shot. ;) I took almost all necessary textures from ONE CD. A few of them, I painted by myself, like the plant textures, or the mirror.I will not write about how to split single texutres into several, if you do not remember, try to find my earlier tutorial.
But I will show you how I created the main texture for my front wall and how to create a good-looking dusty and old mirror.
Look, how I destroyed a beautitul texture. The Guys from 3dtotal, will kill me! (3DT: No we won't, we like the man ;))
I knew well, what my texture should look like. I didn't need a pure and clean concrete texture but I found a good texture to work from (to destroy), also I chose several other texture-maps. Some of them, I used as masks for scratches, some of them for old paint marks and others just for plain dirt. BUT! I needed more. I needed more details. I needed something that can make it easily recognizable that this is an OLD WALL!
And then I figured something out!
What happens when you move out from your old home, taking with you your favorites furniture, your paintings etc.? What will you discover? That you've got very dirty walls, when you take off a painting from the wall.
Those historical marks, I created in Photoshop. I created a new Layer, then using the 'Rectangular Marquee Tool' and 'Feather' at a value of 2 pixels, I filled those selections with a plain light gray color. Then I changed the opacity of the layer a little bit. And thats it.
Those writings in style of graffiti were created on simple white paper, using a black marker. Then I scanned them and using selection method 'Color Range' I delete the white color, which left only the black color of my marks.
