One of the best ways is to organize them as you would in real life - by switches or circuit breakers. If you have a lot of lights in your scene, you’ll want to keep them organized by instances, groups or layers. To adjust the color of your light to the actual color temperature of your particular light, use this website that translates color temperature into color pixel RGB values.Here are some helpful tips to help you set up your scene and work with Light Mix in V-Ray 5. When I got my linen set the way I wanted to, I was able to see the glow from the bulb through the translucent shade. I then created a new emissive material that I applied to the light bulb. However, (back to rule #2, I didn’t use the emissive material as the light source to light the scene, hence the rectangular light). See the Lighting Tutorial for more info) Because I wanted the lamp shade to be something semi-transparent (a linen in this case) I knew that you would see the actual light bulb and thus wanted to give it an emissive material to give the effect of slowing through the linen. Because I want the light to go both up and down, I simple click on the check box that makes this light double sided. Wireframe of Lamp - Notice Rectangular lightĪs you can see, I have a rectangular light (the golden colored rectangle) that fits inside the lamp. In this case, I used the following image.
First thing I do is take a screen shot (if doing a CPU monitor ) or google your favorite tv station or program and search through google images until you find something that you want to put on the TV screen.
With that being said, let’s look at how to make that material. Even during the daylight and with the lights on in the room you can still see the light being emitted from the TV or Monitor. Now turn the lights on and look from the same views. That is EXACTLY how tvs work, LED TVs, LCD Monitors, etc. This should seem fairly obvious when take the time to think about it.
You’ll notice that it sends a massive amount of light out projecting from the screen. Then move to the side of the object or better, move behind it if possible. If you sit in a dark room, turn on a tv, or open your laptop. Let’s take a look at the TV screen first. You’d also be able to remember that I mentioned that about 1000 words ago at the beginning of this post, so congrats on either or both accounts. If you said the TV screen and the light bulbs on the wall sconces, you’d be correct. Essentially, we need more light or to increase our light in the scene? The increase of render settings will increase our rendering time (potentially substantially i.e 10-100 times) As a result, it’s suggested for best results, let’s use a light in the scene and only use emissive materials for the glowing that they’re meant for. Notice the “Splotchy-ness” and uneven lighting quality around the objects? That’s because our render settings are fairly low for the amount of light that is needed to calculate.
Now to better show the emissive quality, I’m going to turn off the lights and the environmental light, leaving the material as the only thing in the scene emitting light (I know, I know I told you never to do this in Rule 2 above, but take a look and you can see why never to do this). Now let’s create an emissive layer and look at the default parameters. First I’ll render the scene that I’ve been using previously with a default material. There are a lot less parameters than the previous two layers, and luckily, they are all fairly straight forward. Now let’s jump right into it! First we’ll create a new material (which I’ll cleverly name “Emissive Material”). Do not use these materials as the sole lighting for a scene.These materials will increase render times, possibly to extreme amounts.I will bring up a few things to keep in mind when using a material that uses an emissive layer. These types of material can be used to create effects such as a neon sign, a glowing lamp shade, or a tv/computer screen. An emissive layer allows the material to emit light. The emissive layer is the final tutorial on the various layers for Vray.
Ok, so I just finished my Architectural Registration Exam study session, my wife is out for a while, and I’ve got a few hours before I’m meeting my sister and her boyfriend for dinner, (for those keeping track of my day)…let’s see if we can finish up the last material layer…Emissive Materials.
