Bloom lighting is used to give lighting a more realistic look, giving shiny halos of light to particularly bright objects, as is seen with most camera lenses. The effect was mentioned in the developer blog for RuneTek 5 as one of the additional graphical effects that will be possible in HD mode with the new engine. Note that bloom lighting does not work with all graphics hardware and drivers, and may fail to work in either OpenGL mode, DirectX mode, or both. Bloom is not supported in Software mode.

Simulated bloom effectsEdit

There are instances where particles are used to simulate bloom effect around specific points of light. The halos of light found in these are NOT bloom effect. They are particles, and they register in the particle count output, which is accessible through the developer console. Here are a few examples of areas and objects where bloom lighting is simulated using particles:

• The 10th anniversary cake.

  

• The spirits in the 2011 Easter event.
• The pumpkins and candles in the 2010 Halloween event.
• The trees and candles in the 2010 Christmas event.

TriviaEdit

• Zanaris was originally meant to be updated with bloom effect with Fairy Tale Part III on 13 May 2010, but technical difficulties had postponed the implementation of bloom lighting.
• There have been numerous cases of turning bloom lighting on causes the game to crash upon entering a world. To resolve this, log back in to the lobby and turn the bloom off before logging into a certain world. In fact, most computers with inferior graphics cards cannot handle bloom and will crash the game instantly. Some players have confirmed that using the "Fixed" screen mode allows the use of the bloom effect after all.
