IPR Functions

This is the IPRProvides artists a quick preview of the image prior to the final render, and efficiently allows for adjusting some elements in the scene such as lights, shaders and textures interactively. An IPR image contains shading and lighting data including some for visibility, in addition to the software render. window with all available functions:

IPR window move and resize

IPR window can be moved to any position, even to another monitor. To move the window drag it using the window title zone. IPR window also can be rescaled to any size, like any other system window. Horizontal size is limited by the size of the buttons in the menu bar. Vertical size is limited to 64 pixels.

Close the IPR window

User can close the IPR window with the “Close” button or closing the window like any other system window.

IPR materials and objects picking

User can select the surface under the cursor with SHIFT+Left click. It is also possible select the object under the cursor with SHIFT+Right click. Currently click over instances is not supported.

IPR window functions

Reload: Stop current rendering and make a full scene reload. This function is used if a change in the scene is not update in the IPR image.
Pause: This button pause/continue current rendering.
Redraw: Redraw the rendering without reload scene, but updating all objects transformations.
Reset: Reset the navigation to it’s initial state (current camera view in Camera mode, or default 3D view in Perspective or Target mode)
Sel Only: If enabled only the selected objects will be loaded in the Octane scene. Remember that to render instances, the instancer object and all the objects to instanced must be selected.
Full Upd.: This function force a full scene reload for every change made in the scene. It must be used to update scene while working with objects with deformations, some simulations and other complex scene changes. Must be used carefully, because reload scene may be very slow in complex scenes.
No Upd: Similar to the “Pause” function (if enabled, the IPR scene is not updated while the user is working with the Layout), but with this switch the Octane rendering is not paused. After disable this switch, the plugin updates the scene to the current state.
Mat. Upd: Enable this button to update and render the animated parameters inside the materials in real time while timeline scrubbing.
Fix Asp.: Fix the IPR window aspect size to the current camera aspect size.
Alpha: This button allow display the current alpha channel.
Half Res: Switch rendering to half resolution, what allow x4 times faster rendering
Sh.Ball: Enable the materials shaderball function. When enabled a material preview shaderball will be rendered in the IPR window.
HDRLS: Enable the HDR Light Studio LightPaint features. Only useful with the LightWave HDR Light Studio plugin.

IPR store, clone and save functions

IPR window has a Store button to store current view in a image buffer. Later at any time user can select the stored images to display them using the numbered drop-down list next to this Store button.

IPR also has a function to clone current IPR image to a new window, that can be moved to any place. Use the Clone button to open this additional window.

Current image can be saved to a JPG or TGA32 file. Use the Save button to open the file dialog window and set the image file name.

IPR focus options

IPR camera can work in three focus options, that user can select with the drop-down menu.

SceneFocus: Use current scene focus options, that must be set in the Render Target camera node.
Autofocus: Use Octane auto focus option.
DisableDOF: This options disable the depth of fieldThe distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. Although a lens can precisely focus at only one distance at a time, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions. source: wikipedia (https://en.wikipedia.org/wiki/Depth_of_field) feature.

Clay Rendering

Enable the clay rendering mode in the IPR. This buttons doesn’t change the clay rendering settings available in the Render Target.

IPR GPUs real time settings

If you have two or more GPUs in your system, IPR window is going to show a switch button for each one. User can enable or disable the GPUs used for rendering in real time without redraw the current image.
