Patchwork 3D 2023 X6

The dimensions and resolution for the image to be rendered are provided in the Dimensions zone.

The Format drop-down list, available for all types of snapshot except cubic VR panoramas, provides access to the most commonly-used sizes and formats. Certain formats, such as User Defined or User Defined in Units allow the dimensions to be provided directly as values. By default, Patchwork 3D proposes the format Defined by Viewport.

Custom formats can be added to this list from the User Presets tab in the Patchwork 3D Settings.

Each editor offers the choice of rendering engine to use: OpenGL, Raytracing or Iray.

The Files zone contains the controls for the creation of an image file.

In this zone you can set:

The following file formats are supported for video output:

The following file formats are supported for video output:

Layered Image Options

The functionality of exporting captures in PSD or PSB file format allows you to export different layers of a view. Each of the exported layers is saved to a layer in the PSD or PSB file.

Snapshot with OpenGL or Raytracing rendering engine

To export a multilayered image, click the button Configure Layered Export to open the Layered Images Options window, then choose the layers to add to the PSD or PSB file from the following layers:

• Composable Image containing three layers: a background, a multiplicative layer, and a layer of the product’s opaque surfaces,

• Composited Image,

• G-Buffer,

• Wireframe,

• Z-Buffer,

• Lightmaps.

Note

The settings defined in this window apply to images exported as PSD or PSB file formats only.

The maximum size supported by the PSD file format is 30,000 pixels in any dimension with a maximum weight of 2 GB.

The maximum size supported by the PSB file format is 300,000 pixels in any dimension.

You can choose to export a layer for each of the following options:

• Export only PSD or PSB file. The editor exports the selected layers to a PSD or PSB file format. In Photoshop, layers will be represented as layers.

• Export only layers as images. The editor exports the selected layers to individual images. The destination directory will receive all the images of the layers in their respective folders.

• Export PSD or PSB file and layers as images. The editor exports both the selected layers to a PSD or PSB file format and to individual images. The destination directory will receive all the images of the layers in their respective folders.

  Example of exporting a video using the option Export PSD or PSB file and layers as images.

Once the settings have been made click on the button OK to save the settings and then press Render at the bottom of the editor. In the window that appears name the image and change its file extension to *.psd or *.psb.

Samples of layers from an exported PSD file: lightmap, wireframe and G-buffer views.

Samples of composable layers and composited image generated using Composable Image and Composited Image options respectively.

Using Composable Layers

The following composable layers can be obtained using the Composable Image option:

• A layer with the background of the snapshot,

• A multiplicative layer. When applied to the previous layer, areas corresponding to transparent surfaces are colored,

• An additive layer which adds opaque areas and reflections on transparent surfaces to the final image.

Example of view reconstruction: over the background layer (left) the multiplicative layer (result of the process shown in the middle) is applied. Then the additive layer is applied on the resulting view to reconstruct the final image (right).

The compositing technique described above allows the substitution of the background while maintaining a correct filtering by semi-transparent surfaces. This would be impossible to achieve with a transparency based on an alpha layer.

However, this technique is not compatible with the use of post-processes. Therefore, post-processes are disabled for rendering of composable layers.

Snapshot with Iray rendering engine

If you have selected Iray as Rendering engine the Iray only layers zone will be available for you to select from the following layers:

• Alpha

• Normal. The rendered image displays a texture of normals.

• Object id works like the G-Buffer. The rendered image displays a different color for each surface used by the product.

• Material id. The rendered image displays a different color for each material used by the product.

Example of a snapshot with Iray rendering engine and the parameter Material id activated.

Once the settings have been made click on the button OK to save the settings and then press Render at the bottom of the editor. In the window that appears name the image and change its file extension to *.psd or *.psb.

The Internal Render Info zone summarizes various settings. The applicable elements from among following information are displayed:

Various options are available in the Snapshot zone, depending on the type of output:

Once all of the settings have been defined, click on the Render button to start the generation of each snapshot used to compose the required output.

You can also Add to Snapshot Batcher to delay rendering until later, or Replace current Snapshot Batcher item with the current settings of the open snapshot editor.
