From c9238e638fd5f6b3e4cf22d879d397dee1b09b48 Mon Sep 17 00:00:00 2001 From: Brecht Van Lommel Date: Fri, 28 Jun 2019 17:06:32 +0200 Subject: Cycles: add back control to render first N bounces with path termination It's found in the Sampling > Advanced panel and 0 by default. This helps to reduce noise in some scenes, while making others slower. --- intern/cycles/kernel/kernel_path_state.h | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'intern/cycles/kernel/kernel_path_state.h') diff --git a/intern/cycles/kernel/kernel_path_state.h b/intern/cycles/kernel/kernel_path_state.h index cdca0b1f9bf..8735e3208db 100644 --- a/intern/cycles/kernel/kernel_path_state.h +++ b/intern/cycles/kernel/kernel_path_state.h @@ -209,8 +209,8 @@ ccl_device_inline float path_state_continuation_probability(KernelGlobals *kg, return 0.0f; } else if (state->flag & PATH_RAY_TRANSPARENT) { - /* Do at least one bounce without RR. */ - if (state->transparent_bounce <= 1) { + /* Do at least specified number of bounces without RR. */ + if (state->transparent_bounce <= kernel_data.integrator.transparent_min_bounce) { return 1.0f; } #ifdef __SHADOW_TRICKS__ @@ -221,8 +221,8 @@ ccl_device_inline float path_state_continuation_probability(KernelGlobals *kg, #endif } else { - /* Do at least one bounce without RR. */ - if (state->bounce <= 1) { + /* Do at least specified number of bounces without RR. */ + if (state->bounce <= kernel_data.integrator.min_bounce) { return 1.0f; } #ifdef __SHADOW_TRICKS__ -- cgit v1.2.3
