Sample Scenes

Here, we provide various scenes, ready for use in Bella GUI (and in some cases, Maya), to help you get familiar with Bella.

Bella scenes are provided as .bsa/.bsx, or as .bsz if they have dependencies. Upon opening a .bsz file in Bella GUI, it will be unzipped (.bsz is just a zip file) with the contained .bsx file being written next to the .bsz file, and with dependencies being written to a res directory, also next to the .bsz file.

Maya scenes are provided as .ma where possible, or in a .zip when they have external dependencies. In the latter case, the .zip contains the .ma file, and a res directory with the dependencies.

Rhino scenes are provided as .3dm with embedded resources.

SketchUp scenes are provided as .bsz for use in Bella GUI, and SU8 .skp for use in SketchUp.


CORE MATERIALS

This scene compares the core Bella material types: lambert, conductor, dielectric, and the common conductor+layer combination. The materials are driven using a single color node.

SMART MATERIALS

This scene compares the Bella Smart materials. The materials in this scene are driven using a single color node.

CERAMIC

This scene demonstrates the Bella ceramic material parameters, which are just color, specularity, and roughness. The materials are driven using a single color node.

PLASTIC

This scene demonstrates the Bella plastic material parameters, which like ceramic, are just color, specularity and roughness. Materials in this scene are also driven using a single color node.

METAL

This scene demonstrates the Bella metal material parameters. A metal may use either the "Custom" mode, in which color is chosen by RGB input, or it may choose from a built-in list of complex IOR presets.

URETHANE

This scene demonstrates the Bella urethane material parameters, which are translucence and roughness. As with the other scenes, materials are driven using a single color node.

DERBY CAR

Nothing special, this is just a simple derby car which demonstrates some methods of creating materials, texturing, using image based lighting.

Download for Bella GUI, or for Maya. Here also is a video tutorial for the Bella GUI, which uses this model.


Skateboard Wheel

This is just a simple scene that can be nice for working with various materials.

un-dispersion of dispersion

This scene demonstrates the Apollo solver's ability to solve very complex caustics. A beam of light is split using prism, then re-combined by the same prism, before arriving at the camera, which looks along the same vector as the light beam.

Candy-coat Test

This model is from an experiment, to emulate the candy powdercoat seen in this reference:

The Bella version is at right, and the file available for download will not render precisely the same, because it uses a different HDRI, and because in the image above, I played with levels to try and mimic post-processing apparently done to the reference. The downloaded model will render like this:

This scene uses the Apollo solver, and applies both denoising and sensor bloom at the end of rendering.

Concrete house (SketchUp)

This model includes a house and trees, both downloaded from 3D Warehouse.

Note use of the Bella Sheet material, which allows rendering single-thickness glass panes. These would cause trouble with a true dielectric (glass) material, since it would appear to the light as though the interior of the building comprised a volume of glass.

Museo (SketchUp)

This is an original SketchUp model of a small museum lit by sky dome & sun. In addition to the skylights, the walls at the far end of the scene are slats to let light into the space.

Porsche 907 Longtail (Rhino)

This model comes courtesy of McNeel & Assoc. built by Kyle Houchens using Rhino 7 SubDs. It demonstrates the use of various types of materials and related nodes.

Download for Bella GUI or for Rhino.


Ring

This is a Rhino scene demonstrating the use of several Bella materials & techniques generally applicable to jewelry rendering.

Download for Rhino, or for Bella GUI.

And here is a second version, with slightly different lighting, and white background.

Download for Rhino, or for Bella GUI.


Butter

This is a scene demonstrating two types of subsurface scattering in Bella. The stick of butter uses the randomwalk Subsurface material, and the wrapper uses a Sheet with Layer+Scattering, with scattering albedo texture-mapped to simulate oil-saturated regions.

Download for Rhino, or for Bella GUI.


Digital Emily

This is a scene set up for rendering the Digital Emily model from the Wikihuman project. It demonstrates how to use the Bella Subsurface material to create realistic skin for the model.

The skin material is not complex, and has been set up to yield a convincing look, regardless of the lighting used.

To demonstrate, the only difference in the following images is the HDRI used to light the scene -- not even one other parameter has been changed.

A slideshow at higher resolution is available for viewing here.

Since redistribution of the assets (OBJ file & textures) does not appear to be allowed by the Wikihuman project, we are providing scenes fully set up, but with geometry & textures removed. Detailed instructions for how to download & import the assets back into the template scene are also provided.

Download the scene for Rhino (instructions here), or for Maya (instructions here).


Preview Scene 1

This is a standalone version of the Bella GUI's material preview scene.
