Tips

If you can't see your model after importing and placing it in the scene, try this:

Check the scale of your model and make sure that it is placed near 0,0,0 in SketchUp before importing it in Lumion.

a) Relocating 3D model perform the following steps:

1 If want to move a 3D model that is imported, choose the Imported models menu, and click the Select and Move free menu

2 Select the 3D model, and if need to select multiple objects use the combination Ctrl+ the left mouse button to draw a rectangular selection

3. Beside that can use the L key to scale the 3D model, the R key to rotate the object, and the H key to move the 3D model vertically

4. If want to copy the selected objects and paste them in a different location, press the Alt key while moving your objects.

Tips

If the 3D model is not moving and didn't lock, try this:

This is because the wrong category was selected. This means, for example, that to move a tree needs to select the Nature category

1 Choose the surface at the driveway, at the material library window click outdoor, choose Bricks, and apply the surface with material Polii Bricks 16 2k

2 The image on the left shows that the bricks are too big for the driveway

To solve this issue, click edit material and need to use the Map scale setting from 5 to 2, to create something more realistic and with the correct proportion

3 Lastly, click the right button to save the change material.

c) Create a swimming pool and make use of the Water material by performing the following steps:

1 Select the Materials menu Choose a water surface for the swimming pool Change water surface to Lumion material Select the surface, at the material library window, click Various, click Water, and Clear lake.

2 Lastly, click the right button to Save the change material

1 Choose a surface on the terrace, at the material library window click indoor, choose Wood, and apply the surface with material Wood floor 042 1024

2 The materials have a certain level of reflectivity and glossiness To solve this issue, click edit material and need to use the reflectivity setting from 0.7 to 1.2 and gloss setting from 0 7 to 1 3, to create something more realistic

3 Lastly, click the right button to Save change material

Tips

If the 3D model is missing faces, try this:

Before importing the 3D SketchUp model in Lumion, the idea is to find grey faces and reverse them

d) The reflection, glossiness and more, perform the following steps:

VRay® for SketchUp is an integrated rendering solution for SketchUp that allows designers to experience their designs in real time as they model, bringing them to photorealism without leaving SketchUp

An interface is a program that allows users to interact with computers in person or over a network An interface can also refer to the controls used in a program that allows the user to interact with the program.

Many things have changed in this new version of V Ray for SketchUp New features, and new icons, among other things. This tutorial offers a quick overview of the functions of V Ray Menu V Ray: Now there are more options called Plug ins SketchUp

VRAY Render Toolbar

This is the main toolbar that provides access to the Asset Editor (settings) and render buttons You can create, save, open and adjust the settings in this window

VRAY Lights Toolbar

Frame Buffer

Works the same for both static and interactive (real time) renderings The rendering is displayed as a separate window that hovers over SketchUp and can be moved to the the second monitor (if available) to keep the SketchUp window free

Closing and reopening the image buffer brings back the previously rendered image The image remains until a new rendering process is started *Closing the image buffer does not mean that rendering is finished Make sure that you press "Stop" first before closing

Viewport render

This is a new feature, similar to Interactive Render, except that it is displayed in the SketchUp window itself rather than in the floating frame buffer.

Panning or zooming, as well as making changes to the model will update the render in real time.

Viewport Render Region

You can select only a part of the viewport to render. This is a good option as it doesn't cover the whole model and allows you to work and render at the same time and see the result of your changes.

Rendering smaller regions also consume less computing power and runs faster than larger renderings.

You can switch between viewport and framebuffer rendering during rendering by clicking on one of them.

Before we start with the compositions, we should know the render settings Interactive rendering is a great way to adjust materials, lighting, and more in real time What is real time?

Real time means you can see what your rendering looks like as you change materials and lights.

We’ll start by showing the Settings I use in my Interactive Vray Renders

to Nvidia Ai

After that, we move to the Camera setting.

The Camera rollout controls the way the scene geometry is projected onto the image

The cameras in V Ray generally define the rays that are cast into the scene, which essentially means how the scene is projected onto the screen

The most important place to adjust the Camera settings is the Camera rollout. If you need to fine tune the settings, you can also use the Advanced Camera Parameters rollout

Type Specifies the type of camera Here you can set the desired output for VR rendering or standard imaging

Standard A standard pinhole camera

VR Spherical A camera useful for producing latlong images for spherical VR use

VR Cubemap A Cubic/Box camera in which the cube face is arranged in a single row It is useful for generating cubic VR output

Stereo Enables or disables the stereoscopic rendering mode Stereoscopic images are rendered "side by side" or "on top of each other" depending on the output layout option. You do not have to readjust the image resolution as it adjusts automatically.

Exposure Enables the Physical Camera Exposure. When enabled, the Exposure Value, F Number, Shutter speed, and ISO affect the image brightness.

Exposure Value (EV) Controls the sensitivity of the Camera to the scene lighting levels. The result is a brighter or darker image. If Auto Exposure (by clicking on it) is enabled, the Compensation value becomes available. When the Auto button is enabled, the ISO, F number, and Shutter speed are locked

Compensation This option is enabled when the Exposure Value (EV) is set to Auto. It is an additional compensation for the automatic exposure value in f stops. A value of 1.0 makes the result twice as bright and 1.0 twice as dark.

White Balance Renders objects in the scene that have the specified colour as white in the image Note that only the hue is considered; the colour brightness is ignored There are several presets that can be used, most notably the Daylight preset for exterior scenes You can click on the Auto option to have V Ray adjust the White Balance For more information, see the White Balance example below

Auto Values This option is available when Auto Exposure/White Balance is used It stores the auto calculated Exposure and White Balance from the last initialized render as values that can be reused in the next render by pressing the check button ( ) This option helps if you have manually set different values for the Exposure and White Balance and want to return to V Ray best suggested values (for the last render) Manual refresh is required to get the values from the last render by pressing the update button ( )

Depth of Field Turns on depth of field sampling.

Defocus Determines how sharp or de focused the image might look outside a plane determined by the Pick Focus Point command This option is also known as Focus Range

Focus Source Chooses the way the camera focus is determined

Fixed Distance The focus of the camera is fixed at the Focus Distance value Use the button on the right to select a point in 3D space to set the camera's focus distance The distance between the rendered camera and the point is calculated and the result is then used as Focus Distance This calculation is not automatic and must be repeated each time the camera is moved Camera Target The focus distance is automatically calculated before rendering begins and corresponds to the distance between the camera position and the target Fixed Point The focus distance is automatically calculated before the rendering starts and corresponds to the distance between the camera position and the selected 3D point Use the button on the right to select a point in the scene.

Pick Point Determines the position in 3D space by picking in the viewport where the camera is to be focused.

Focus Distance Affects the Depth of Field of the Camera and determines which part of the scene is in focus.

Exterior Vray

DOME LIGHT is a type of VRay Light that shines inward on the scene as if it were coming from a spherical or hemispherical light source outside the scene's perimeter. This light is often used for image based lighting with HDR panoramas as the environment.

c) Locate the Dome Light in any position into the drawing (in this example, I locate it in front of the building)

The arrow represents the direction of sun faces You can change the points of the arrow and the shadow also will be change

2) Once you’ve added the Dome Light, it shows up in the Lights Section of the Vray Asset Editor. Change the Default Background HDRI to the one you like by clicking on the Texture Slot next to Colour/Texture HDR.
