Product Information

An open space with little or no lighting after dark where it will be safe to test the clothing at night When you configure the Roughness value for your Materials remember that most objects have some degree of shininess. Even surfaces that you wouldn't normally think of as reflective tend to show some kind of specular highlight when hit by a strong enough light source. Connect all of the Material Expression nodes to their corresponding inputs on the Main Material Node. When completed, the Material Graph should look something like this:

Displacement maps are an enhancement of the bump mapping or normal mapping techniques applied to textures. Normally an Occlusion Map is the type of image you will use for Displacement maps. The actual technique employed in Enscape is called quadtree parallax displacement mapping for optimum performance. It’s worth noting that Displacement maps are incompatible with transparent materials so the entire “Transparency” section becomes unavailable where a displacement map has been applied (including mask textures). Furthermore, the brightness of Displacement maps cannot be further adjusted or inverted when editing the texture inside the Enscape Material Editor itself. You can also use this value to mimic depth of field in mirrors. Amount The shininess of the reflection.

Orca film has a snowflake-like molecular structure that scatters the light to all sides and that does not create hot spots and this material also does not let light through. And since it is made from non-toxic materials it will not react with your grow lights or the air inside your room. White bed sheet As you decrease the distance between the car and the pedestrian, the visibility of each of the colors increases. Still, at any distance, the retro-reflective material wins the visibility contest. Roughness plays a major role in determining the shininess of a Material. The Roughness input takes a value from 0 to 1.

The sphere on the far left has a Roughness value of 0, and the light source is reflected as a sharp, precise highlight. As the Roughness value is increased from 0 to 1, the highlight becomes blurrier and the sphere appears less shiny. This option can be great for large-scale sealed grow operations but for small-scale cabinet grows it usually is an overkill and it is too hard to properly attach this polymer to all the walls without cutting it in multiple places. If you have no other option then you can also line your grow room walls with white bedsheets as they are quite reflective and easy to work with. Have your observer (“driver”) assistant(s) hold the brightest flashlight; stay alongside them to help rate the visibility of the test assistant. C3 anti-detection film is another variant of Mylar and it is a material that has been specially designed not to let any heat trough. Because of that it can be a great addition to grow rooms that are constructed in cold climates. But you have to be careful in hot climates where you will need a lot more ventilation to counteract that heat as well as those light reflection properties.

The best radiator reflector on the market is the nifty radiator reflector kit from Radflek which provides enough reflective foil to insulate between 3-6 radiators in your home (depending how large they are of course). These fabrics are coated to make them reflective in different ways. It is applicable to any casual wear or active sportswear with custom reflective patterns, for aesthetics or safety in the dark. Compared with silk screen printing, it is much brighter and has better washing performance.

the left mirror has a Gloss of 0.98, the middle is Gloss = 1.0, and the right one has Gloss of 0.90. Extra: Do you think pedestrians can accurately estimate how visible they are at night? To find out, ask people if they think a driver in a car can see them if they are dressed in the specific colors you tested. Compare their estimates with the test results you obtained. This menu allows you to choose a color that should be added to any semi-transparent areas of your material. Very much like colored glass. Roughness affects the shininess of a Material regardless of the Specular value. Even when the Specular value is set to 1, the specular highlight will still be blurred to invisibility when the Roughness value is 1. Adjusting the Specular value will have no effect on the Material if Metallic is enabled. In Fig. Demonstration of the Fresnel effect., this behavior is demonstrated for a perfectly reflective Material

however, the reflections could become noisier. Samples Number of cone samples averaged for blurry reflection. The Specular input can also have an effect on the shininess of a Material. Pushing the Specular value closer to 1 will make the reflections or specular highlights of a Material appear brighter and stronger. Lowering that value closer to 0 will weaken the specular reflections until they are almost invisible. This foil looks like a great way how to reflect the light but it really is not a great option because this foil tends to wrinkle and crease a lot and all those wrinkles and folds will create an uneven light distribution that can even burn your plants. In this science activity you will put three different “colors” (bright, fluorescent and retro-reflective) to the test. Which one do you think will increase visibility most in poor light conditions?

The default specular value of 0.5 accurately reproduces the measured specularity of the vast majority of real-world objects. Therefore, you should not need to modify the Specular value for most of the Materials you make. You can of course increase or decrease the specular value as an artistic choice, but straying too far from 0.5 can make the Material less physically plausible. Air has a refractive index of 1.0 – so light rays travel through it in a straight line -, water has an index of 1.33, window glass 1.52, and, for example diamonds have an index of 2.42 – they bend light quite heavily.

The lower the Roughness value, the more mirror-like the Material will appear. When Roughness is 0, the Material behaves like a perfect mirror. Another great thing about orca film is that it has also some anti-mold properties and the company states that it can reflect up to 95% of the visible light spectrum! There are various versions of this material that you can get but the best ones are those that have some kind of a texture that will help with light reflection and will stop wrinkles from forming.
