Hi
during the rendering, the GI cache is used to estimate the GI in each shading point. A user-defined number of GI samples (RED::OPTIONS_RAY_GI_CACHE_INTERP_SAMPLES_COUNT) is requested from the cache around the shading position. Then, the GI samples are averaged together to compute the estimate. The greater the samples count, the softer the interpolation. Be careful as if you use too many GI samples for interpolation, you can produce light leaks (light passing through obstacles).
When the number of samples is too high (orange case), GI is interpolated from both sides of the wall and light leak is visible), otherwise (blue case) most of the interpolated GI samples are on the correct side of the wall and light leak is not visible.
Hi, I often also have this problem with light leakage. Could you explain how to change the number of GI samples?
Hi,
You can change the OPTIONS_RAY_GI_CACHE_INTERP_SAMPLES_COUNT value in the Rendering Settings dialog:
Best regards,
Thanks!
