Apply a Standard Material
to the surface. Then set the level of Transparency
using the Transparency
slider. (pic 1)
Note this type of material supports up to 16 levels of Transparency
when rendered. See our Knowledge Base Article
: section Expanded Settings Groups: -> TransparencyWhat do the sliders & buttons in the Standard material do?
To get a glow from the light bulb add some Emissive
. Light sources such as Spotlights
and Linear Lights
cast light on to surfaces, so surfaces that need to glow (self lit/self emissive) need to include some Emissive
amount in the material. See also above article.2.
In Build Mode
(especially) where you are building your Scene
there are reduced lighting and other effects to maintain reasonable screen re-draws. Light bounce is not visible until you add an effect that produces it such as HyperLight
(only seen on final render, not in Preview
) or Global Illumination
. These types of light bounce only produce a single further bounce. You need full ray-trace based rendering to enable open levels of bounce and reduced bounce for softness.
Materials will further add to the lighting in the Scene
when their Reflectivity
values are suitably set.
For interiors use the Indoor Style
which includes all the core effects to get the best results, it includes Sky Light
(recommended to set to High). (pic 2)3.
Yes, you would need to use Spotlights
cast no shadows so the light past an intersecting object is not clipped. OmniLights
, Fill Lights
and Linear/Area Lights
that do not caste shadows have a faster rendering performance than Spotlights
due to the shadow calculations required. See What do the sliders & buttons in the Spotlight properties do?
and Why are Spotlights not casting shadows?4.
You would, yes. You can use the Nodes Replacement
to quickly set the lights (assuming you are able to find an alternative if your AutoCAD 2017 is not able to help with making nodes).
You can Group
objects such as Spotlights
and lamp holders etc together. However, there is no features/interface developed to allow that grouping to be saved out and used elsewhere as it's own separate object. It has been suggested by some users for something similar - to save in the library a Group
for future use.
Pro users can however, use the Merge
feature to bring assets from one Scene
in to another Scene
. It currently does not include Merge
of the Group
object, but the lamp model and the lights would be merged in, thus providing for re-usability. You would then need to make a new Group
if you needed to manipulate those objects as a Group
Hope that helps answer your questions fully. Any more questions on lights just ask. And, let us know if there's anything else we can help with.
