Live Home 3D for iOS Tutorials – Speeding Up 3D Performance


In this video we will share some tips on how
to speed up the app performance while working in 3D. By default, the app works with enabled Lights
and Shadows option. It means that all light sources, shadows and reflections will be present
in a 3D view. The more light sources and reflective surfaces you add, the more time it takes to
render a scene. Depending on the project, you may notice that
your movement became a bit more sluggish. That is a sign that some optimizations are
required. Here is what you can do: Disable Lights and Shadows option. By doing
this, you increase the speed of your movement in 3D, while the render quality remains sufficient
for the normal work. You may always enable this option again when
good quality screenshots or videos are needed or you simply want to see a scene in the best
quality. But you really do not need photorealistic image during modeling routine. In most cases disabling Lights and Shadows
option solves all issues with sluggishness, but if it doesn’t, consider doing one of
the following: 1) Make sure the scene is not overloaded with,
so to say, “heavy” 3D objects. These are objects that contain excessive number of triangles. Usually such items are imported into the project
from online 3D resources, these objects may significantly decrease movement speed. Even
opening such projects, after saving the work, may become painfully slow. Extremely detailed items should always raise
your suspicion. The Type and Representation dialog lets you decrease the object’s level
of detail and improve the program performance as a result. 2) Draw walls carefully. Red circles on the
floor plan indicate places where walls join improperly. Fixing these issues will speed
up your project. 3) Objects shouldn’t plunge into the floor,
ceiling or walls. To be sure that an object is properly placed, activate the Glue By (appropriate
object side) option, and move the object around to let it snap to a floor, ceiling or other
nearby surface. If you keep the Lights and Shadows option
enabled and still want to speed up work in 3D, here is what you can do: – In the app Preferences set Shadow Casting
Lights to Nearest 2 or Nearest 4. This way, you limit the number of light sources that
are taken into account when rendering the current 3D scene. – Turn off light sources located outside the
room you are working on, and those which aren’t critical for the current 3D scene. You can
control light sources in the Light Properties tab of the Inspector. – Don’t use too many reflective materials.
The program performance can decline if you apply reflective materials to a large number
of objects. – Hide objects that aren’t critical for your
current work, or those that are invisible from the current point of view. Use the Project
Tree to make objects visible and invisible. For example, if you have several trees outside
the house, hide them while you are editing the interior. – Deactivate the Cast Shadows option in the
Inspector where possible. Shadows may not be visible in the following circumstances:
when a flat object is attached to a bigger one (picture on a wall or rug on the floor);
an object is very small (pen on a table); one object is inside another (books on a bookshelf,
or a TV set in a niche), there maybe other cases as well. Well, that’s it for now. We will continue
with useful Live Home 3D tips and tricks in our next videos to make your work as smooth
as possible.
