Rendering, lighting and shading

Preview and High-Quality Rendering

Two rendering modes are available in PocketStudio:

  • Preview
  • High-quality

To switch between modes, press the F2 key.

You can switch between these modes both in the scene editor, the sequence editor, and the player/rendering views. In other words, you can see the scenes, the sequences or you entire movie in either one of these modes.

Preview
High Quality

Here is short description of these two modes:

  • Preview: the preview mode use the same kind of technology than the technology used in most if not all real-time rendering engines, including or especially video game engines. This preview mode has the advantage to be the fastest possible way by which GPUs can render 3D scenes today. However, it is not easy in this mode to simulate lighting or rendering effects that contribute to the feeling of photo-realism (such as depth of field, motion blur, reflections, soft shadows, subsurface scattering, etc.). For this reason, this mode is ideal for blocking scenes (a process called layout in animation), animation, lighting, camera or shading adjustments, or previewing scenes or sequences with real-time framerates (above or equal to 30fps).

    The preview mode is also the mode of preference for things such as VR and AR for which, real-time framerates (framerates greater than 30 frames per second, up to 60 or 90 ideally in the case of VR) are necessary.

  • High Quality: if photo-realism is important and speed is not critical, then the high-quality rendering mode offers a suitable built-in solution. It is built upon a technique called ray-tracing which is slower than the preview mode but produces images of professional film quality. As this technology progresses, we shall get real-time ray-tracing on highly complex scenes in the foreseeable future.

    If you want to use the high-quality rendering mode, you will need a Nvidia RTX compatible GPU (many Nvidia GPUs from the current generation whether from the GeForce consumer line or the Quadro professional line do). Ray-tracing is a high-memory consumption technique: the higher the memory of your RTX GPU the better.
