Quick3DCloset® User's Guide

This option allows you to create photorealistic images of the design.

Once the project has been finished, proceed to making the render with the lights and perspective you want.

The window below will let you configure the render options:

The available options are:

1. Resolution: Increasing the resolution will increase definition. If you select the “Customize” option, you will have to add width and height values manually:

NOTE: To save time, it is recommended to do the tests in low resolution and increase it when the outcome is as expected. If the lines of the door frame are staggered, it will be necessary to increase the resolution.

2. Quality: There are 3 available options: Best, Good and Low. The best quality will take more time to render. Below you can see images of the 3 qualities available:

3. Reflection: Here you can increase or decrease the reflection in floors and walls. (NOTE: the reflection value changes the light. The higher the reflection is, the more light the render will have.)
   Below you can see two images of the same project: one without reflection and the other with maximum reflection values:

4. Lights: This option allows you to increase or decrease the lights of the render. (NOTE: If it looks good in "3D mode" but the render is light or dark, it is easier to adjust the lights using this bar. When changing "Quality", it may also be necessary to readjust the lights a bit by using this option.)
5. Advanced: This section allows you to configure advanced aspects of the render such as:
• Show ceiling: This option will show the ceiling in the render.
6. Hardware acceleration: Hardware acceleration is only possible with compatible graphics cards, specifically from the Nvidia RTX 3050 family and higher. Hardware acceleration will be available only for the slow and very slow rendering modes.
• None: No hardware acceleration. Exclusive use of the CPU for scene generation. 
• Nvidia OptiX GPU: The render will utilize NVIDIA's OptiX technology whenever the graphics card is compatible. This hardware acceleration option has a significant impact on scenes with high reflection and refraction loads. 
• Nvidia CUDA GPU: CUDA stands for Compute Unified Device Architecture. It allows offloading the calculations necessary for rendering to the graphics card processors, relieving the CPU. The use of CUDA acceleration is recommended for simple scenes with few reflections or when the card is not compatible with OptiX technology.
• Nvidia CUDA GPU + CPU: Hardware acceleration will be used through CUDA technology in parallel with the CPU.

After setting up all the render parameters, click on (), and a new window opens (V-Ray Frame Buffer) where the render itself will be created. It may take some time to open the window, depending on the complexity of the kitchen.  

This window allows you to:

• See a color render in progress. 
• Save the color render, once completed.
• Apply color corrections to the rendered image such as exposure, contrast, saturation and many others.
• See a list of renders created and review past renders individually or two at a time.
• Save information about the rendered images such as time it took and others.

The options in this window are explained in the “Edit Photos” section.

NOTE: If you click on the render button during a "2D view", the window below will appear:

NOTE 2: Clicking on the "Photo" option with the "multiple window" mode will ask you which one you want to "render":

When you click on this button, the following window will display with all the "renders" made to compare the parameters and the final result. Notice that once the project has been closed, this list will disappear, so you may have to save the render(s) you want. (NOTE: If no render has been made, the window will not be displayed):

Here you can find the following options:

1. List of images: A list with all the renders made and their parameters (quality, resolution, lights, etc) will be shown on the left.
2. Preview: A preview of the selected render will be shown on the right.
3. Save as, edit and remove image buttons: Here are the commands to edit, save and delete a selected image:

4. Zoom buttons: These commands allow you to increase or decrease the image size in the preview [2]:

When clicking on the "Photo" button to generate a photo-realistic image or when clicking on "Edit photos", the “V-Ray Frame Buffer” window opens with the following features:

• See a color render in progress if you clicked on "Photo". 
• Save the color render, once completed.
• Apply color corrections to the rendered image such as exposure, contrast, saturation and many others.
• See a list of renders created and review past renders individually or two at a time.
• Save information about the rendered images such as time it took and others.

NOTE: To 'load' the image, double-click on it in the 'History' field [4]. This will allow it to be edited using the tools available in [5].

The following options are available in it:

1) TOP TEXT MENU

The text menu at the top of the Quick3DCloset - V-Ray Frame Buffer window contains the main options. Most of these options are also available directly from the toolbar for easy access.

First of all, it is important to note that when a render with medium, slow or very slow quality is generated, a series of independent channels are created that contain render elements such as reflection, refraction, noise, blur, etc. By default, the image is shown with all channels mixed (RGB), but we can see each channel separately. This is useful for professional image editing. These channels are also called layers.

VFB Settings

The settings mainly control visibility, location of stored renders and presets, amount of disk space to use and navigating within the VFB.

Bottom buttons

• Save and close – Saves parameters configuration and closes the VFB Settings dialog.
• Close – Closes the VFB Settings dialog without saving the changes.

Render View Tab

The Render View tab controls zooming, panning and comparing of rendered images. Some of the options are available only when “Show Advanced Settings” is enabled.

• Zoom Multiplier – Zoom multiplier factor when we rotate the mouse wheel. The default value is 2.
• Resize VFB on Resolution Change – When enabled, loading an image from history or starting a new render resizes the render window to fit its resolution. 

The following values are available when the "Show advanced Settings" option located to the right of the tabs, is activated:

• Zoom:
• Outside Margin – The fraction of the displayed region allowed to be outside of the displayed image. Useful when panning the image while zoomed in.
• Compare:
• Compare Fit Mode – Specifies how to fit the compared images when their resolutions are not the same. You can choose between Horizontal, Vertical and Center.
• Split Hit Tolerance – Specifies a number of pixels around the split lines when deciding they are close enough to be dragged with the mouse.
• Center zoom on Split Line – When enabled, zooming in/out, while in history compare mode, is centered around the split position(s).
• Keyboard Pan:
• Use VFB 3.x keyboard pan – When enabled, keyboard pan is in image pixels. When disabled, keyboard pan is in fractions of the displayed image.
• Keyboard pan display fraction – Specifies the number of pixels (or fraction of the image) to pan with the keyboard.
• Keyboard pan shift multiplier – Specifies a multiplier for the pan amount when the Shift key is pressed.
• Bucket outlines – Controls the appearance of buckets in VFB during rendering.
• Different color by bucket – Each core from local rendering machine receives its own color for the bucket outlines and machine name. Each DR render server will have its own single unique color for the markings.
• White – All bucket outlines, names of DR render servers and local rendering machine are in white.
• Black – All bucket outlines, names of DR render servers and local rendering machine are in black.
• None – No bucket outlines and markings are displayed during rendering.
• Resize VFB on Resolution Change – When enabled, loading an image from history or new render start also resizes the VFB to fit.

Render Region Controls Tab

Not available in Quick3DCloset

History Tab

The History tab controls the render history settings such as location, amount of disk space to use and visibility parameters. Some of the options are available only when "Show Advanced Settings" is enabled.

• Enabled – Enables/disables render history, where the V-Ray VFB keeps a history of previously rendered images.

• Recent –  Shows a list of recently used locations for loading layer tree presets.
  
  

Shortcuts Tab

The Shortcuts tab displays a table, containing all Shortcuts for navigating through the VFB image as well as controlling the panels of the new VFB. Please note that the VFB window must have the current focus for the shortcuts to take effect.

The shortcut controls available with the keyboard and the mouse are explained below.

2) VFB TOOLBAR

3) OPTIONS AT THE BOTTOM OF THE VFB WINDOW: PIXEL COLOR INFORMATION

4) RENDER HISTORY

The Quick3DCloset VFB keeps a history of previously rendered images, and lists each with a number, thumbnail, and textual details in the Render history panel. Up to four images can be called from the history to be compared in the VFB (as shown below). History files are stored as .vrimg files in a user-specified folder. Render history settings can be configured in the VFB Settings window.

The keyboard keys from 1 to 9 can be used to quickly load the first 9 images from the history to the VFB.

The History panel with notes/name, resolution/time, and shortcut key info displayed. Right-clicking on an image in the VFB history brings up a pop-up menu with some useful options:

5) LAYERS

The redesigned Quick3DCloset - V-Ray Frame Buffer includes a suite of color corrections and tools for adjusting the image. The tools are added as layers and displayed in a layer tree. You can enable or disable a particular tool using the visibility icon () to the left of its name.

The following options are available at the top:

By default, when Quick3DCloset is installed, the following layers are shown depending on the render quality. As we have seen previously, more layers/effects can be added by pressing the "Add a new layer" button: 

• Stamp: – Allows adding text to the image.
• Display correction: – It is used to modify the exposure of the image. When displaying or hiding this layer, it acts on the rest of the layers shown below:
• White Balance – Correct the white balance moving the dial from a low value of 3000 (cold, bluish image) to a high value of 10000 (warm, yellowish image). Recommended values are typically around 6000.
• Color Balance – Correction allows you to select dominant color between Cyan and Red, Magenta and Green, and Yellow and Blue. This correction can apply to the entire image or can be applied selectively to impact Shadows, Midtones or Highlights.
• Hue/Saturation – Correct Hue, Saturation and Luminosity of the image.
• Exposure – Make corrections to Exposure, Highlight burn and Contrast.  These corrections can be applied in conjunction with the Force Color Clamping for better results.  The recommended value for Highlight Burn is around 0.75. With lesser values, the image tends to lose volume.
• Lents Effect – Opens the lens effect control panel, explained.
• Denoiser – It does not work with Fast render. Removes noise from the image by blurring the dots. Its value can vary between 1 (maximum blurring, and therefore noise elimination) and 0 (no blurring).
• Source: RGB (for fast quality) or Source LightMix (for medium, slow and very slow quality). The Source LightMi option shows a list with the lights of the render and allows you to modify their intensity (raising or lowering it) and their color.

Each layer has a context menu. Right-click to display it:

VFB Shortcuts

These shortcuts navigate through the VFB image. Please note that the VFB window must have the current focus for the shortcuts to have effect:
