Abstract
3D modelling software has its importance and requirement priority in various fields, mostly in design sectors. Visualization, creating 3D models, representing scenes, and adding animation to objects can have their complications, but with 3ds Max software results can be expected with the large availability of modifiers, cameras, and lights made available for the modelers to create something with their creative perspective. By going through this chapter, readers can have an insight into topics like lights, camera paths, modifiers, Boolean, pro-Boolean, viewport, mesh, AEC extend by which modelers can have their desired output as a result. It also gives a glimpse of how material editors can be useful in giving a realistic look to any object or scene being created. Usage of various lights is also included with the importance of cloning objects. Cloning objects is an important aspect when modeling is considered. Casting shadows to clone objects can be interesting and complex. This chapter makes it easy by giving a clear perspective of its usage and importance.
TopIntroduction
A spot light is used when there is a requirement of a direct source of light. Being emitted by a cone, it allows us to easily have control over properties like width i.e. the area light should cover. Any object closer to a spotlight gets bright enough and harder (A. S. Baskoro et al. 2015). Target spot lights are very much useful in casting shadows as the light directly falls on the object. Shadow can be casted by enabling shadow property in the modifier list of the respected light, by clicking the shadow checkbox. A free spotlight has no targeted area. It has no specific focus. It is mostly used to create a glow effect depending on the scenario. A free direct light produces a parallel light ray over any object in a single straight direction same as the natural phenomena where sunlightfalls on the earth’s surface (I. Haryanto et al. 2015). The most common usage of a free direct light would be using it to generate sunlight in any specific environment. The colour can easily be changed and the position as well can be adjusted easily in the given 3d space. Figure 1 show shadow created by target spotlight.

The above-mentioned lights are the most commonly used sources to produce the required light effect over any object so as to enhance it when rendered.
TopObject Shadows
On creation of objects or any scene/environment, placing lights would be a task that has to be done with considering the position and accuracy. Adjusting the saturation and brightness with intensity has to be done to get the right amount of focus on the object or a scene.
Enable shadows in General Parameters and activate shadows by clicking the check box available under shadows. Fig 2 shows the changes made in light properties.(D. Fritsch et al. 2017)

TopComparative Study On Copies And Instance Of Lights:
Keeping rendering as a main factor, render time when instances are used is much less compared to copies. Copies generally require more space compared to instance as it allows to work on an object with its properties same as the original objects as in reference. When copies are made, it becomes an individual object with its own properties which eventually takes up some memory space and also much more time whilst rendering. (Deryabin et al. 2017)
