Brightness and
Falloff — [Text
only] — October 2012, Updated October 2013.
Bryce features Linear Lighting Workflows which is a pre-requisite to get physically
plausible results. This means that materials and light sources work linearly. Light
sources can have linear and square falloff and they almost behave as such. This PDF
shows what light intensities can be expected to reach objects at different distances.

Soft
Shadows — [Text
only] — February 2018.
An object lit casts shadows on the lit surface on which it stands. Depending on
the size of the light source and its distance to the object, the edge of the shadow
fades, gets blurred, the edge gets soft at the transition to the lit surface. Hard
edged shadows appear unnatural. 7 pages, 36 pictures (3,540 KB).
Linear
Workflow — [Text
only] — March 2014.
The document Brightness and Falloff shows that the lights in Bryce have linear
properties. Here it is shown that Bryce renders linear and encodes only RGB images with
Gamma, but not the ones exported as 96-bit. If images are loaded into the Picture Editor
for materials, they are linearised. Bryce works completely with linear data like every a
modern renderer. This is shown in this document. 3 pages (321 KB).
Parallel Gel
Light — [Text
only] — October 2015.
All Bryce lights accept gels (cookies, gobos). With them, light can be given a form,
or cast shadows. It is also possible to render embossed objects. Additionally, the
somewhat unfortunate control of the Distant Light is discussed. (1,224 KB).
Specular to TA
Light — [Text
only] — May 2016.
Diffuse light illuminates the objects usually. Specular can assume the function of
the light, even objects can act as light sources if the scene is rendered with True
Ambience (TA). 6 pages, 21 pictures (5,128 KB).
Hypertexture Obscure
Light for Indoors — [Text
only] — November 2017
Square Parallel Lights with hypertexture boosted ambience can be used as light sheets
to illuminate rooms and individual walls if the scene is rendered with True Ambience
(TA). An alternative to dome lights and fill lights. 8 pages, 32 pictures (1,623 KB).
Lightless
Bright — [Text
only] — June 2021
A scene lit without any light source, renders very fast. Interesting results.
4 pages, 19 pictures (1,915 KB).
