RenderThrottleIray

Stop Wasting Time--Start Rendering With RenderThrottle for Iray!

RenderThrottleIray is a render optimization preset manager add-on for Iray in DAZ Studio.

RenderThrottle provides a new preset type, one for DrawSettings, then allows you to apply a DrawSettings Preset, a RenderSettings Preset, and switch Draw Style with a single click!

RenderThrottleIray introduces an exciting new workflow by allowing you to quickly switch between responsive interactive viewport renders, and final quality offline rendering with a single click. Interactive Lo; and Interactive Med Presets start an Interactive Viewport render with low Max Samples; which will keep you from killing your computer while getting interactive feedback from Iray. The Render Hi preset will give you a beautiful high quality render (but you will have to wait).

With RenderThrottle, you can use optimized Iray Draw Settings for quick feedback while editing materials, cameras or lights and then with a single click, kick off a final quality render.

Stop wasting time--Get the most out of Iray, and start rendering with RenderThrottle for Iray!

User Guide

Installing Actions

After running the Daz installer, you should have a Scripts/RenderThrottleIray folder in your Content Manager:

You can use the presets here, but installing Custom Actions allows you to have easy access to RenderThrottle.

1. Double-click !RenderThrottleIray Install Actions Script
2. You will see new icons in the Render menu and Main ToolBar.

Presets

There are two types of RenderThrottle Presets; Interactive and Render

• Interactive Presets will start Iray in the active Viewport
• Render Presets will stop Iray in the active viewport (if running) and launch a Render.

When applying a RenderThrottle Preset, 3 things happen:

1. A corresponding RenderThrottle file is loaded which updates various DrawSettings
2. A corresponding RenderSettings Preset is loaded (These presets are found in Scripts/RenderThrottleIray/Render Presets)
3. The Interactive or offline render is started

Interactive Lo

Most responsive Viewport rendering (low Max Samples; Interactive Mode).

Interactive Lo

Medium quality Viewport rendering.

Interactive Hi

Hi quality Viewport rendering.

Render Lo

Lo quality render.

Render Med

Medium quality render (close to DS defaults).

Render Hi

Final quality renders.

Reset

Restore default Render Settings; cancel any interactive render.

Customizing Presets

RenderThrottleIray allows you to create your own presets (If you are comfortable saving RenderSettings presets and editing text (json) files).

The presets in the Render Presets directory are NOT encrypted and can be read/edited as plain text so you can see what they do.

Note: You will have to re-install the product to get back to factory defaults (unless you make a copy before making changes). Be careful as you make customizations.

As an example, you can download, an alternative "RenderThrottle Reset" preset that only stops the render--no RenderSettings or DrawSettings preset applied.

RenderThrottle_reset_empty.zip

RenderSettings

You can change the RenderSettings applied by updating the corresponding .duf file. For example, if you want to customize the "RenderThrottle Render Hi" RenderSettings, you can save a RenderSettings preset over the file at Scripts/RenderThrottleIray/Render Presets/RenderThrottle Render Hi.duf. When you then invoke "RenderThrottle RHi" from the Render Menu or Toolbar, this preset will be applied.

DrawSettings

The DrawSettings presets are the .json files in the Render Presets directory and are simple Parameter Name, Parameter Value pairs and can be edited in order to make customizations.

Technical Notes

• In order for the Interactive Presets to work, Daz Studio requires that the DrawSettings pane be visible. If it is not part of your favorite layout, you may want to include DrawSettings so the Pane does not pop-up when using the presets.
• When using the Reset preset during an active render, the application may take a minute to cancel the render (This is also the case when done without RenderThrottle).
• Don't use all the actions or what to move them? Use F3 to customize.

Supported Versions

Daz Studio 4.9+
