questions with correct answers
What does projection do? (Cameras) - Correct Answer-Projection toggles the camera's capability to simulate perspective. What does perspective do? (Cameras) - Correct Answer-Camera will render objects with perspective intact. Simulate a real-world view. Scene needs to have depth of field. Commonly used in 3D games. Larger foreground objects block smaller background objects when the camera is straight on and you can't see around corners. What does orthographic do? (Cameras) - Correct Answer-Camera will render objects uniformly, with no sense of perspective. Objects don't need to have depth of field. Objects are flat. Commonly used in 2D games. All objects in the foreground and background are the same size and are visible, you can see around corners, and the whole world/ scene has a slight angle to eat. NOTE: Deferred rendering is not supported in Orthographic mode. What is FOV Axis? (Cameras) - Correct Answer-Field of View Axis, (When Perspective is Selected) it's available in Horizontal or Vertical What is FOV? (Cameras) - Correct Answer-The camera's view angle, measured in degrees, along the axis specified in the FOV Axis drop-down. What is Clipping Planes? (Cameras) - Correct Answer-The distances from the camera to start and stop rendering. What does it mean when a clipping plane is near? (Cameras) - Correct Answer-The closest point relative to the camera that drawing will occur.
What does it mean when a clipping plane is far? (Cameras) - Correct Answer-The furthest point relative to the camera that drawing will occur. What is occlusion culling? (Cameras) - Correct Answer-enables the occlusion culling for this camera. This means that objects that are hidden behind other objects are not rendered, for example if they are behind walls. Occlusion Culling is a feature that disables rendering of objects when they are not currently seen by the camera because they are obscured (occluded) by other objects. What does a culling mask do? (Cameras) - Correct Answer-It includes or omits layers of objects to be rendered by the Camera. Assigns layers to your objects in the inspector. What is the culling mask used for? (Cameras) - Correct Answer-is used for selectively rendering groups of objects using Layers. What is a background? (Cameras) - Correct Answer-It's the color applied to the remaining screen after all elements in view have been drawn and there is no Skybox. The light component - Correct Answer-Lights determine the shading of an object and the shadows it casts. Render mode (Light component) - Correct Answer-Use this drop-down to set the rendering priority of the selected Light. This can affect lighting fidelity and performance. Auto (Light component) - Correct Answer-The rendering method is determined at run time, depending on the brightness of nearby lights and the current Quality settings.
Not all packages in the Unity Asset Store are free, some are free, but many come with a price. You can browse and filter for packages by category when signed into the Unity Asset Store. A history of packages that you have downloaded, for free or purchased, are stored under the My Assets menu in the Unity Asset Store. (Package Manager and Unity Asset Store) - Correct Answer-TRUE Scale Factor and Convert Units (Importer options) - Correct Answer-Adjust how Unity interprets units. When you optimize the file, you compress mesh data in Unity to reduce its size, which can improve performance. (Importer options) - Correct Answer-TRUE You CAN'T enable specific FBX settings, such as Import Visibility, or Import Cameras and Import Lights. (Importer options) - Correct Answer-FALSE, you CAN Unity DOESN'T supports importing models from most popular 3D applications, such as, Blender, Maya, 3DS Max, and Cinema 4D. (Importing OBJ and FBX files) - Correct Answer-FALSE, it DOES What is the first material parameter in the standard shader? - Correct Answer- Rendering mode What does rendering mode do? (Materials) - Correct Answer-This allows you to choose whether the object uses transparency, and if so, which type of blending mode to use. Opaque (Materials) - Correct Answer-Is the default, and suitable for normal solid objects with no transparent areas.
Cutout (Materials) - Correct Answer-Allows you to create a transparent effect that has hard edges between the opaque and transparent areas. In this mode, there are no semi-transparent areas, the texture is either 100% opaque, or invisible. This is useful when using transparency to create the shape of materials such as leaves, or cloth with holes and tatters. Transparent (Materials) - Correct Answer-Suitable for rendering realistic transparent materials such as clear plastic or glass. In this mode, the material itself will take on transparency values (based on the texture's alpha channel and the alpha of the tint colour), however reflections and lighting highlights will remain visible at full clarity as is the case with real transparent materials. Fade (Materials) - Correct Answer-Allows the transparency values to entirely fade an object out, including any specular highlights or reflections it may have. This mode is useful if you want to animate an object fading in or out. It is not suitable for rendering realistic transparent materials such as clear plastic or glass because the reflections and highlights will also be faded out. Albedo (Color and transparency) - Correct Answer-Controls the base color of the surface. Specifying a single color for the Albedo value is sometimes useful, but it is far more common to assign a texture map for the Albedo parameter. This should represent the colors of the surface of the object. It's important to note that the Albedo texture should not contain any lighting, since the lighting will be added to it based on the context in which the object is seen. Alpha (Color and transparency) - Correct Answer-This value of the Albedo color controls the transparency level for the material. This only has an effect if the Rendering Mode for the material is set to one of the transparent modes, and not Opaque. Picking the correct transparency mode is important because it determines
What are probuilder shapes? (Prototyping and Greg boxing/white boxing) - Correct Answer-High poly shapes; they can have many more polygons to their structure, and therefore allow us to create shapes that demand more structural complexity. What are the standard Unity shapes called? (Prototyping and Greg boxing/white boxing) - Correct Answer-Primitives Physics systems can be added, and we can add scripts to control characters, such as the player capsule primitive, to run and test a Greybox prototype. (Prototyping and Greg boxing/white boxing) - Correct Answer-TRUE Object mode in pro builder (cube button) - Correct Answer-when you select in Object mode, you are selecting the entire Mesh. Vertex mode in pro builder (3 dots connected by lines) - Correct Answer-Select vertices (the point where two or more angles meet, for ex. The corner points of a cube) and perform detailed editing such as vertex splitting and connecting. Edge mode in pro builder (triangle shape) - Correct Answer-Select edges and perform semi-complex geometry editing, and edge loop modeling techniques. Face mode in pro builder (polygon shape) - Correct Answer-Select faces of an object to perform basic tasks like moving, extruding, or even deleting them. What does curve mode do in the animation window? - Correct Answer-It displays a resizable graph containing a view of how the values for each animated property changes over time. All selected properties appear overlaid within the same graph view. This mode allows you to have great control over viewing and editing the values, and how they are interpolated between.
An animation curve CAN have multiple keys - Correct Answer-TRUE What do tangents control in an animation curve? - Correct Answer-They control the shape of the curve between the keys. You CAN edit Position, Rotation, and Scale of an object's animation. - Correct Answer-TRUE You CAN edit a single key or multiple keys when working with curves; however, manipulating multiple keys is limited. - Correct Answer-TRUE You CAN edit multiple tangents at once. - Correct Answer-FALSE, you can only edit one tangent at a time. How do you create sharp changes in an animation curve? - Correct Answer-Choose one of the Broken tangent modes. What is Dope Sheet Mode? - Correct Answer-It's the animation window showing the keyframe positions of all animated properties within the animation clip. How do you set your image as a sprite? - Correct Answer-1. Click on the asset to see its Import Inspector.
- Set the Texture Type to Sprite (2D and UI).
- Set the Sprite Mode to Multiple to slice several elements and click on the Sprite Editor button. Filter Mode determines how crisp or detailed your sprite will extract. When importing 2D pixel art, set your Filter Mode to Point (no filter) to force texture pixels to become blocky like small, 8-bit, pixel art. Otherwise for larger, more detailed, painted, or 3D modeled art, set your Filter Mode to Bilinear
Why is UI Scale mode important? (Rect Transform and Canvas) - Correct Answer- It's important for consistency across all devises and dimensions! How do you add terrain to your scene? (Rect Transform and Canvas) - Correct Answer-GameObject > 3D Object > Terrain Diffuse Texture (Terrain Layers) - Correct Answer-Represents the base color Texture of the Terrain Layer. Normal Map Texture (Terrain Layers) - Correct Answer-Contains the normal information for your Terrain Layer. What are the RGBA channels of the Mask Map Texture? (Terrain Layers) - Correct Answer-R = Metallic G = Ambient Occlusion B = Height A = Smoothness (Diffuse Alpha Becomes Density) Specular? (Terrain Layers) - Correct Answer-The ________ highlight color of the Terrain Layer. Metallic? (Terrain Layers) - Correct Answer-The overall metallic value of the Terrain Layer. Smoothness? (Terrain Layers) - Correct Answer-The overall smoothness value of the Terrain Layer
Tilling? ( Terrain Layers) - Correct Answer-The _______ settings that apply to all Textures the Terrain Layer uses. Baked (Light Modes) - Correct Answer-Unity pre-calculates the illumination from Baked Lights before runtime and does not include them in any runtime lighting calculations. Baked Light never changes, it is baked in real-time. Realtime (Light Modes) - Correct Answer-Unity calculates and updates the lighting of Realtime Lights every frame at runtime. Unity does not precompute any calculations for Realtime Lights Mixed (Light Modes) - Correct Answer-Unity performs some calculations for Mixed Lights in advance, and some calculations at runtime Why are the complex calculations performed in advance by Baked lights so helpful? (Light Modes) - Correct Answer-It reduces shading cost at runtime and reduces the rendering cost of shadows. When are Baked Lights useful?(Light Modes) - Correct Answer-They are useful for lighting things that won't change at runtime, such as scenery. Baked Light Behavior (Light Modes) - Correct Answer-Unity bakes both direct lighting and indirect lighting from Baked Lights into lightmaps. For more information on using lightmaps, see lightmapping. Unity bakes both direct and indirect lighting from Baked Lights into Light Probes. For more information on using Light Probes, see Light Probes. Limitations of Baked Lights (Light Modes) - Correct Answer-You cannot change the properties of Baked Lights at runtime.
Mixed (Light Modes) - Correct Answer-They combine elements of both real-time and baked lighting. You can use this light mode to combine dynamic shadows with baked lighting from the same light source Indirect multiplier (The Light Component) - Correct Answer-r value to varies the intensity of indirect light. Indirect light is light that has bounced from one object to another. The Indirect Multiplier defines the brightness of bounced light calculated by the global illumination (GI) system. If you set Indirect Multiplier to a value lower than 1, the bounced light becomes dimmer with every bounce. A value higher than 1 makes light brighter with each bounce. This is useful, for example, when a dark surface in shadow (such as the interior of a cave) needs to be brighter to make detail visible. Shadow Type (The Light Component) - Correct Answer-No, Hard, Soft, and each one requiring additional processing as it progresses. No Shadow uses the least processing and Soft Shadow the most, because it is the most realistic. Culling Mask (The Light Component) - Correct Answer-Use this to selectively exclude groups of objects from being affected by the Light. For more information, see Layers below. What is a Cookie? (The Light Component) - Correct Answer-It's a mask that you place on a Light to create a shadow with a specific shape or color, which changes the appearance and intensity of the Light. They're are an efficient way of simulating complex lighting effects with minimal or no runtime performance impact. Effects you can simulate with them include caustics, soft shadows, and light shapes What are some light modes? (The Light Component) - Correct Answer-Render Mode: Use this drop-down to set the rendering priority of the selected Light. This can affect lighting fidelity and performance.
Auto: The rendering method is determined at run time, depending on the brightness of nearby lights and the current Quality settings. Important: The light is always rendered at per-pixel quality. Use Important mode only for the most noticeable visual effects (for example, the headlights of a player's car). Not Important: The light is always rendered in a faster, vertex/object light mode
