-===== Buffer =====+===== Buffer Group =====
  
 +The buffers in LightWave 3D 2018 are set up in groups. Selecting one of them will show a different set of buffers in the following pop-up control.
 +
 +The following buffer groups are available by default:
 +
 +  * **(standard)** This is a group of the basic buffers the renderer produces.
 +  * **(extra)** These are mainly shading and volumetric related buffers created by the renderer.
 +  * **(custom)** Any custom AOVs added by the user.
 +
 +Light buffer groups will show up in this pop-up as well.

-The ambient occlusion options control how LightWave3D computes the ambient occlusion buffer. exrTrader will just pass these settings to LightWave, it does not compute the buffer.+These options allow you to edit the per buffer settings that LightWave provides in the Render Properties/Buffers tab.
  
-Ambient occlusion is computed by shooting multiple rays into the scene for every surface. If the ray hits something, that will darken the currently sampled surface spot+These settings are saved by LightWave with the scene and are provided here as well for convenience
-=== Mode ===+=== Adaptive Sample ===
  
-The mode can either be Infinite or Ranged.+This determines if the buffer is used by adaptive sampling to check if a pixel needs more samples. This is done by comparing the pixel values in the buffers using the Adaptive Sampling Threshold set in the Camera Properties.
  
-Infinite causes the rays to proceed until they hit something regardless of the distance.+=== Noise Filtering ===
  
-Ranged causes to rays to only take a certain distance from the surface spot into account, anything beyond that will not darken the surface. +This will allow the noise filtering in LW to affect this buffer as well. Noise Filtering has to be active in the Render Properties/Render tab as well.
-=== Range ===+
  
-If the Mode is set to Ranged, this will set the maximum distance of the AO sampling rays. Anything beyond that distance from the sampled surface spot will not be taken into account. +=== Reconstruction Filter ===
-=== Use Transparent Shadows ===+
  
-This option allows the ambient occlusion rays to take the transparency of the surface they're hitting into account. It will also increase the render times.+This allows you to pick a different reconstruction filter on a per buffer basis.
