Rendering Quality in Enscape

The Rendering Quality Slider

One of the main goals of Enscape is to allow our users to achieve great results without having to adjust a vast range of settings.
This is why Enscape has all the attributes that define the real-time performance condensed into one single slider. 

Make sure Enscape is running and click on the Visual Settings Window button.

The Visual Settings Window will open on the Main tab by default and the Rendering Quality slider is to be found at the bottom of that dialog.

This slider determines how much effort Enscape should put into calculating the lighting in your scene. If you ever experience a low framerate or otherwise bad performance (perhaps because you’re running Enscape on a computer with low level hardware, or a very complex project) setting this slider to a lower setting will result in improved performance.

With a few exemptions, this is the only setting controlling the actual performance when Enscape is rendering in real-time. So what are the available settings, and what do they affect?

Draft

When rendering in Draft mode, only direct light will illuminate your scene. In real life, light will bounce off surfaces, lighting up the environment. With Draft Mode, this process is disabled, ensuring maximum performance in Enscape. Reflections are also affected by this setting and  in Draft Mode, reflections will be heavily simplified, showing more of an estimation of the environment of your project than the project itself. This mode, however, apart from granting great performance, can be useful for anybody not interested in lighting their scene at all. You’ll get almost an equal brightness, regardless of where in your project you are, although the result of course won’t look as impressive.

Medium

This is where Enscape begins to show off its impressive Path Tracing abilities. Light will now bump off the first surface it hits, taking information such as the surfaces color and intensity, eventually hitting a second surface and illuminating that too. Reflections will begin to display the actual environment – although Enscape still uses a complex algorithm to determine what objects to display and what to hide according to their size and complexity, as we want to maintain an acceptable frame-rate, after all.

High

Setting the Rendering Quality “High” will improve the aforementioned procedures – lighting is calculated with even more precision, and reflections will hide less objects than on “Medium” setting.

Ultra

Lastly, the “Ultra” setting. The difference to “High” isn’t all that drastic and is essentially but two bounces of light rays are being calculated instead of just one bounce, resulting in an even more realistic image – but, frankly, you’ll rarely see the difference to the “High” setting at all. Not in non-VR, that is!

Rendering Quality in VR

Since Virtual Reality has far higher demands on your computers hardware than non-VR Enscape, we’re using techniques to make sure you’re still getting the most fluent experience possible. This is why when VR is enabled, the rendering quality settings can generally be treated as one level of quality lower.

This means the “Draft” setting will behave as a more simplified version of the non-VR “Draft” setting, “Medium” can be compared to non-VR “Draft”, “High” will introduce the Path Tracing process mentioned above, and so on.

Other Settings Affecting Real-Time Performance

In addition to the Rendering Quality slider, there exists a set of further options that can affect the performance of your real-time rendering in Enscape. These are located in Enscape General Setting’s General Settings button window’s Rendering tab and you can get more information about each of these settings here.

Optional Rendering Performance Settings

Optional Rendering Performance Settings

The real-time display in Enscape is using a dynamic resolution – the walkthrough is displayed using as higher resolution than the window size and your monitor resolution can allow. However, if Enscape detects your hardware is having difficulties maintaining a decent frame-rate, the Auto Resolution option, if activated, will tell it to downscale the resolution for better performance.

This setting does not affect any render exports, only graphics during your movement through the Enscape scene in real-time!

However, should your scene look blurry in Enscape, you might want to disable this setting to check if that’s the reason – you might have to dial down the Rendering Quality in turn, though.

Render Export Quality Settings

Apart from the mentioned settings, there’s also a few settings affecting only the export quality of still image renderings, panoramas and video files, but not the real-time performance.
To be precise, you could probably call the majority of available settings “quality” settings, depending on your personal taste, but these four will improve the output quality while either increasing render time, or output size.

All of these options are located in Visual Settings window under the Output settings tab.

The Rendering Export Quality settings

  • Resolution
    Select the export resolution for both, your still image renderings as well as your video exports using this dropdown menu. You can either choose your window resolution, any of the given presets, or a custom resolution up to 8192 x 8192 pixels. Please be aware that exporting renderings in such high resolutions can overwhelm your graphics card, in extreme cases causing Enscape to shut down.
  • Compr. Quality
    The compression quality slider  determines the output bitrate of your video files. This setting does not affect render time, only the resulting video file size. So feel free to dial this setting up to Maximum. For even higher quality, dial it all to the right to ‘Losless’ – this, however, will result in a series of PNG images – easily hundreds of them – that you can then combine to a video file using third party software. Keep in mind not to save this video on your Desktop, or you’ll have a lot of files to move around!
  • FPS
    The FPS (Frames Per Second) setting decides how many images are generated per second of your video. Twice the amount of frames per second, for example 30 -> 60, will result in twice the time it takes to render the video, but will also make for a smoother playback.
  • Panorama Resolution
    The Panorama Resolution allows you to choose the quality of the panoramas generated using Enscape. You can choose a resolution from “Low” (2048 x 1024 pixels), “Normal” (4096 x 2048 pixels) to “High” (8192 x 4096 pixels)
