| TIPS |
| 1. Realistic Dust Dust tends to accumulate from a particular direction, but not only that, it also tends to be more visible on surfaces pointing away from the viewer than it is on surfaces pointing at the viewer. Ensure you exploit both these effects to give the desired result, and notice that this effect is important on large flat surfaces too (it’s always easier to see the dust on the farther floorboards, at a steeper angle to your view, than it is to see it on the floorboards beneath your feet). |
| 2. Not Just Dust It need not just be dust that you create with this shader. It is just as easy and useful to create a covering of snow, or of cobwebs, or of soot, or dirt, etc. |
| 3. Use the Angle Don’t just have the dust layered from straight down all the time either.....if an object is close to a wall, perhaps more dust will be laying on the surfaces facing the open expanse of the room than those close to the wall. You can angle the direction that the dust is layered from, in order to achieve this sort of effect. |
| 4. Adding Detail To The Dust Some very fine dust may indeed appear as a plain, even coating, but chances are the dust will be a little irregular, comprised of some pieces large enough for the eye to pick out separately, as well as gaps in the dust, or areas which are thicker than normal. Use the noise parameters for the dust to achieve the sort of effect you are after, depending on just what sort of dust it is you are creating. You could also use a texture map by using TG Dusty Texture Map too, to give the dust some structure and variety. |
| 5. Removing The Dust Don’t forget that the dust need not look like dust....it is possible to use the shader to create a tarnished look, where the reflectance properties are changed, but the underlying colours remain much the same. |
| 6. Using the ShaderLab 2 Mapping Options Changing the mapping (UV/ Object / World etc) in ShaderLab 2 will alter the way the noise in the dust is generated, but will NOT alter the way the dust layer is laid onto the surface. |
