Open a .vrscene
A .vrscene file can be opened in Chaos Vantage in one of two ways:
FIle > Open Scene > Select the .vrscene;
or you can drag-n-drop the .vrscene file directly into Chaos Vantage and it automatically renders the scene.
A full list of hotkeys are found in Help tab > Mouse and Key shortcuts.
The following shortcuts mentioned while recording this tutorial were set with the 3ds Max navigation preset.
Hold the middle mouse button to move the camera sideways (dolly).
To orbit, hold the Alt key and drag with the middle mouse button.
Ctrl+Alt+middle mouse button lets you smooth zoom in and out. You can also scroll the mouse wheel to zoom in/out.
In Free look mode, you can use the W, A, S and D keys to navigate in the scene. Press the F2 to exit the mode.
The E and Q keys move the camera up and down.
While in Edit mode, holding the right mouse button allows you to use the W, A, S and D keys for navigation as well.
With the latest versions, the shortcut for Free look mode is not F2 but `.
You can drag-n-drop any supported file directly into Chaos Vantage to load it.
When loading a scene, if the assets (textures, proxies) are missing from their original paths or the scene folder, Chaos Vantage looks for them next to where the .vrscene file is in a folder that has one of the following names:
assets, maps, proxy, textures, vray_proxy
LUT and HDRI
LUT files can be loaded from the Post tab in Chaos Vantage.
Clicking on the current LUT file shows a list of recently used LUT files and also lists all LUT files in the same folder as the currently loaded LUT.
HDRI maps can be loaded from the Load Environment button. Click on the currently loaded HDRI to show a list of recently used HDRI maps and a list of all HDRI maps in the same folder.
You can rotate the environment from the Rotation option and adjust the intensity using the Intensity option.
If a scene is being rendered and you drag-n-drop a .vrmesh or .vrscene file you can choose to Merge the new asset with the currently opened scene or Open the new file.
This example merges a few .vrscene files and adds a .vrmesh file and assigns a material from the scene to the .vrmesh.
In addition, you can rotate, scale and move each object around. First enter the Selection mode by pressing the selection (Use the Esc key to deselect all objects in the scene.) button (or hotkey Q). Select the object and press W for moving, E for rotation and R for scale. Press the Q key to go back to selection.
You can also hide/unhide any object from the Objects tab.
The Materials tab can be used to assign any material to the selected object using the Assign to Selection button.
Configuration (.vrdx) Files
Once you make changes to your scene, you can save them as a configuration .vrdx file for later use.
Go to File > Save scene config file and save the .vrdx file.
In this example, we show two interior light configurations - one for daylight and one for night/dusk light, that we save and then compare.
We use LUT files to enhance the lighting and tweak the lights' intensity and color to match a day or night feel for the scene.
Save scene config file option saves a .vrdx file with the name of the scene by default. This configuration file is always loaded with the scene.
The Save scene config file as... option allows you to save a .vrdx file with a different name and load it when needed.
When loading a scene in Chaos Vantage, the default camera stored in the .vrscene file is used.
Navigating through the scene, you can save many camera views and go back to them when needed.
Press the Save New Camera Slot button in the upper right corner (s created, which you can rename.). A new camera slot from the current view i
Another way to save a camera is to select an Empty slot and hold the Save Camera button for the drop-down menu to appear. Select the Save This Cam Slot - it saves the currently selected camera view. Then you can rename it.
You can always go back to the camera that comes from the .vrscene file by selecting Home from the drop-down.
You can render a high quality snapshot from the current view. Go to Tools > Render a High Quality Snapshot. In the pop-up window you can select the resolution and the Samples for the render. The more Samples you use, the better the quality of the render, but at the cost of render time.
You can also enable the Save as defaults option to set the current output settings as your default.
Choose the output directory, name and format.
When the render is in progress you can Stop and save the frame the quality is sufficient, or Pause, or Abort the render.
Recording Camera Movement
To start recording camera movement, go to the Tools tab > Record Camera Movement or from the record button on the bottom right ().
To mimic recording of a walkthrough enter Free look mode. The camera movement is recorded as a new camera slot in the Camera side tab while you walk around . You can tell that the saved camera slot is a recorded camera movement by the red outline around the thumbnail.
You can stop the recording from the same button ().
To preview the recorded camera movement open the Animation Editor by clicking on the EDITOR button to expose the animation tracks. Drag and drop the camera from the Camera list in the Camera animation track.
To render the recorded camera go to Tools > Render High Quality Sequence or from the teapot render icon () while still in the Animation editor. Choose the render resolution and press Start. You are prompted to select the output directory and file name.
