But this case is not even a rare, it is probably unique, and this may be an exterior visualization, in which the diffuse glow of the sky is simulated by the special parametric HDRI map named VRaySky. A special case is when the scene is really having no sources of direct light and it is fully illuminated by the secondary illumination. If we create at least one light source in the scene, the default lights will be disconnected immediately. However, the property of the default secondary lights of 3ds Max is such that they automatically shut off when the any source of light are in the scene. To tell the truth, the correctly set lighting with a good scene geometry almost never give the unwanted surprises on the rendering, and in most cases you don't need to set anything but final resolution.ĭefault lights are needed for the viewport and rendering, without light sources, set manually by the user, to look not solid black, but with the geometry of objects, already lit by default auxiliary light sources. This is true not for V-Ray only, but is an absolute concept for any rendering application. Only in some situations, when the rendering has some parasitic artifacts, we need some slight tuning to get rid of them. We got to fully concentrate on the actual scene setup. But, there are some hints and tricks, which you will learn from this tutorial and there is nothing difficult in them and they all will be explained.Īt first, we have to make clear that there are starter settings, that may be beginning of the any rendering, for not to draw our attention each time to any possibly incorrect options. Like, actually, the separate settings for interior and exterior as well. phase option and to look intently at the Irradiance map sample passes, supposedly controlling the calculation process and many other shamanistic superstitions.Curiously enough, but there are no really universal one-size-fits-all setups. Then to begin the Irradiance map calculation with the enabled Show calc. That firstly you need to run the rendering in a test mode, with the visible samples of the V-Ray sampler on and, by a sample map, long and boringly try the optimal settings to soften and eliminate aliasing to loose the much time for trying than to start the competently tuned rendering. Other think there is no any magic and all you need is the long and difficult work with the renderer parameters for each new scene. That there supposedly are some settings, just like the "magic wand", which by checking some ticks in covert places lets to have the amazing results despite the actual quality of the 3d models, correct lighting setup or beauty and realism of the present scene composition.
Only the chosen people know the secret checkboxes and values that allow creating realistic 3d renderings, which hit the awards and admiration of the all observers. Its also about artistic intent - so I assume you are going for an early morning feel.One believes there are some simple setups, which are carefully hided from them by professionals by keeping the tuning secrets in a strict confidence.
IES files are usually free from manufacturers websites.Ĭhange your camera settings for now to Auto and let Vray take care of exposure and white balance until you are ready to tackle that. Its also worth downloading IES profiles for spots, this will give you actual cone and penumbra values of real world lights.
So in you set scene, you might want to place some fill light in the exhibition space to spill into the cafe area. Yau also have to think like a photographer and consider fill lights and secondary lighting, particularly in parts of the scene that don’t receive any environmental lighting. Its worth using a Dome light with an HDRI image for general scene lighting (its also very efficient as Vray offers adaptive Dome lights now so you don’t have to put portals in the windows. I see you have set the main lighting from the Sun and Simple portal lights in the windows. The emissive material on the globe lights needs to be set to 50 or some such or choose a different lighting method like,a sphere light or turn each globe into a mesh light, this will give you much more control over the effect and appearance of these fittings as you can separate the light from the material, so as these are likely to be frosted / translucent glass you can Geta more realistic look for these pieces.
So in your case changing the Scalar value of 80000 on the spots to 100W (for the exhibition spaces) immediately makes things look a bit more realistic with more balance in light and shadow.
Straight off, I would always recommend that you change the light scale from the default scalar to Watts, which allow you to balance your lighting using real world values.
