vRoom v1.2 (build 154) for Lightwave 2015.3 (Currently only available upon request)

Changes in 1.2

  • Mac OSX release.
  • New radial mode to simulate the interiors of circular or curved buildings.
  • New room geometry stretching options to make simulated rooms larger or smaller.
  • Greatly enhanced FPrime integration. Users can now alter all variables, that do not require a geometry rebuild, interactively. Other variables are protected from being altered.

Download and demo

Below is the download link for vRoom. To use vRoom demo, please run Lightwave in Discovery mode (i.e. without the dongle in place).


Changes in version 1.1

When compositing into some plates, it was noted that the insides of buildings appeared very dark and no detail could be seen. With this in mind, the user can now specify a solid colour (with random hue and brightness variance) and use this instead of image library interiors.

In the event that there are no internal images to be looked up, this colour will be rendered instead. An option to randomly shift the hue of window garnish images (blinds, curtains, etc) has also been added.

Here's a brief example of a building that uses only a single image (for the blinds):

vRoom v1.0

vRoom is designed to simulate the interiors of buildings and the glass panes through which these interiors are seen. Previous to vRoom a Lightwave artist had three choices when it came to the windows on a building:

  1. Have completely reflective windows that you cannot see into.
  2. Have nothing inside their building.
  3. Laboriously hand craft each room and using regular mapping techniques.

Option 1 is sometimes suitable, but not always and even if it is one must handle the subtle glass distortion effects needed for a convincing render. Option 2 can result in faster turnaround times but it has obvious drawbacks, particularly in the case of the high rise example building shown below. The building looks incomplete and lifeless. Option 3 will partially get the results desired, but only after a substantial investment of an artists time. However, if changes are then desired, all rooms must then be re-edited. vRoom was made to solve this issue by creating a shader that will automate this laborious task and give artists options that were previously unavailable.

The same shot with vRoom applied:
