Texturing/Shading (cont.)

To map the porcelain jar tags, first I placed the tag onto the main texture, in order to place an appropriate adjustment. Once the first tag is placed, I duplicated the jar, and I replaced only the tag texture. I used only three different tags, when I placed it in the scene, I rotate the jars in order to show a half of each word in the tag, and this made it look like many different tags due that not all are fully readable.
This way saved alot of time, instead of placing/adjusting a new texture for each jar, and the results are non-iterative, too.


DirtyNut (an automatic dirty) was used for the stone elements to give a more credible aspect for the stonework since this shader places dirt where two surfaces are contacted. This kind of dirt could be created using BodyPaint but this automatic dirt was faster than painting it in the stone walls maps.

BodyPaint was a great help to paint any textures (like the book texture) directly into the objects becauset some objects canít be textured using the typicall mapping projections (plain, cylindric, cubic, etc). BodyPaint allows to paint in all directions and so, I can paint the sheets edge and the sheets body for the book paper object, or retouch some woods (selves and table) which not looks nice at borders using typical projections.


The most unknown material for me was the volumetric shader for the fire/smoke (Pyrocluster) but finally seems I get success with the appropriate parameters.

Lighting

For this scene there are four main sources to simulate. The Sun, the Sky, the Fireplace and the Stove. Each source needs some lights to show its full and rich nature.

(For Photoshop users, I suggest downloading all the images that follow and place them in separate layers (sorted) in a single document. Hidding/unhidding the layers will show a more noticeable changes between stages, rather than seeing it separately.
Itís like start from a black photographic studio and turn on each light group when the next layer is activated, try it it's fun :) )
