6 MODULES146· Bspline Filter: The bspline filter uses a bspline function to weight the samples.It gives results comparable to gaussian filtering but suffers less fromblurring. A value of 1.3 to 1.5 is recommended.· Catmull Rom: The catmull rom filter creates sharp images but may sufferfrom ringing, just like the lanczos and mitchell netravalli filter. A size of2.5 is recommended.· Sharp Triangle Filter: In this triangle filter variant one sample effects onlyone pixel. This way the first impression of the image looks sharper andthe image noise is high frequent.· Sharp Gauss Filter: In this Gauss filter variant one sample effects only onepixel. This way the first impression of the image looks sharper and theimage noise is high frequent.· Sharp BSpline Filter: In this BSpline filter variant one sample effects onlyone pixel. This way the first impression of the image looks sharper andthe image noise is high frequent.• Size: The pixel filter size defines the number of neighboring pixels will betaken in account to for sampling.» Options: You may enable or disable certain rendering features globally.• Optimize for Many Light Sources: In scenes with many light sources or geometrylight sources rendering may slow down. Activating this flag allowsthe renderer to optimize the light calculation by reducing the quality slightlywhich significantly speedsup rendering. While you don’t recognize the qualityloss in most situations, there may be scenes that may suffer from heavynoise when this feature is turned on. In such scenes you may need to disablethe optimization to get a clean render result.• Number of CPU Cores: Sometimes you may want to limit the number ofraytracing cores VRED uses to have some processing power left for otherapplications. This settings is a runtime only setting and it does not influenceany cluster machines.
