This page gives some basic information on IPR within Houdini as well as on how to incorporate the interactive renderer into your workflow.
|
Before starting an IPR, make sure a camera is set. You can set several cameras and then switch between them.
1. Create ROP
Create a V-Ray Renderer node and a V-Ray Renderer IPR node. This can be done in several ways:
|
For more information, see the Rendering page.
2. Configure ROP
Configure the render settings within the Export Tab and the IPR Tab of the V-Ray Renderer node. To navigate to the specific tabs, do one of the following:
|
You can have multiple V-Ray Renderer and V-Ray Renderer IPR nodes with different settings in a scene. |
|
3. Render
Start the IPR in one of the following ways:
|
If vray/vray_ipr nodes aren't created in the out Network, clicking the IPR (VFB) button on the V-Ray Shelf creates a vray node and starts interactive rendering in the VFB. If necessary, configure the render settings as explained above. Clicking the Render button or the Show VFB button, also automatically creates a vray node if none has been previously created. |
|
You can have multiple cameras in a scene. Each camera may be configured to use specific parameters and show the scene from a different angle (or just part of the scene). To select a camera, open the VFB and Shift+Left-click on the Start interactive rendering button.
|
You can have multiple IPR settings in a scene. To select different settings, Shift+Left-click on any of the IPR (VFB) or ROP Parm buttons in the V-Ray Shelf and select the settings you want.
|
In addition, the IPR rendering refreshes whenever the Region Render area is redrawn.
|
V-Ray for Houdini supports interactive rendering in Houdini's Render View. To benefit from this feature, go to Render View > Render button.
Note that the Use V-Ray Frame Buffer option must be disabled. |
You can also use the Render Region option, if you go to Scene View (viewport).
