At this stage, we focus more on details of the scene. _ Omni light is used to create lighting for those street lamps. We add some more details into the scene such as street lamps and interior lights. That should take care for the environment light. This will not affect the final image since we will change to a higher setting later on. The render’s quality looks really bad because of the low setting. The shadow is filled with purple color and there is light coming from the sky. We also add a single Target Direct Light with a blue color to simulate the light from the sky. To make the image look much brighter, simply increase the value of GI environment from 1.0 to something like 7.0, and also change the value of Exponential colormapping some. It looks very dark at this point, but the lighting is starting to show the effect of the sky. _ Light cache with Subdivs at 200 and sample size at 0.02 _ Irradiance map and Lightcache for 1st and 2nd bounce At this stage, we use a very low setting for the test rendering in order to get a quick preview of the image. In the Environment tab in Vray setting dialogue, a sky bitmap is applied into GI and Reflection/refraction slot and leave the value at 1.0Īfter that, we can go ahead and test render. A lot of purple in the shadow, cooler color from the sky and warm color for the street lights these are the things we need to aim for in the final image. We experience the color of the sky when it is at late afternoon and find a good high-res of the sky at that moment. Starting with environment light first, it is a good practice to spend some time looking for reference images or photos of the lighting. This is one of the effective ways to give the image extra realism.īesides that, some of the materials in the scene have Vray DisplacementMod such as the brick side walk and grass. The point here is to create more highlight for the images at night time. The materials have a lot of reflection and highlights. There is no tweaking in the materials at this point yet until the lighting is done.Īll the materials in the scene are optimized by using Vray materials. TexturingĪll the materials are applied to the model. The scene is also lit by a lot of light coming from the retail stores, restaurants and cars on the street. It is a late afternoon/dusk kind of lighting when there is still light from the sky and a slightly warm color from the sun. At this point, the overall lighting is sketched out. Every element in the entire model is organized into layers.
This will be a very busy scene in the evening when there are a great number of highlights and shadows. Unlike interior lighting where you have to spend more time to make sure every detail in the room is lit perfectly, exterior lighting is easier to set up but still challenges the artist. It brings not only the look and feel for the image, but also helps to visualize the design in reality. Lighting is one of the most important parts in 3D visualization rendering.
