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.
