LuxCoreRender v2.1beta1 released

Post by Dade » Mon Oct 29, 2018 12:58 pm

Beta1released

New LuxCoreRender v2.1beta1 release is available.

v2.1 release notes are available here: https://wiki.luxcorerender.org/LuxCoreR ... Notes_v2.1

LuxCore new features:
  • File name resolver
  • New texture: Divide
  • New texture: Remap (bring a value from one range into another range)
  • Three new textures for accessing the object ID: raw object ID (range 0 to 0xfffffffe), normalized object ID (range 0 to 1), object ID interpreted as color
LuxCore bug fixes:
  • Fixed a bug in OpenCL Bloom plugin
  • Fixed clamping of denoiser output, which was happening in some scene setups
  • The Linux binaries don't use SSSE3 instructions anymore so they now work on some old CPU
  • Fixed a bug in OpenCL code for imagemap wrap black and white
  • Fixed a difference between OpenCL and C++ code in SchlickBSDF_CoatingSampleF() affecting all glossy-related materials
  • Fixed a problem in variance clamping with TILEPATH
  • Fixed a problem in Glossy material OpenCL code
BlendLuxCore new features:
  • Add option to use the Bidir engine for viewport rendering (useful in scenes with very complex light paths, where RT Path preview does not work well)
  • New option in the math node: Divide
  • New textures in the utils section: Remap (bring a value from one range into another range), Object ID (can be used to randomize a material across multiple objects)

found a bug - when using the bidirectional engine, enabling the samplecount AOV stops the sampler from doing anything - 0k samples/second, 0 samples, however it still shows rays/sample correctly. Not sure if this is a blender plugin specific bug, or a bug with luxcore itself.

BiDir has support only for a very small set of AOVs and it doesn't includes SAMPLECOUNT AOV. It sounds a problem inside the scope of Blender plugin.

So how's the CPU usage for people using windows and beta1 with opencl? I'm still getting only 15-20% on cpu when rendering with opencl(alphav4 goes to 100%)

EDIT:
Also a small question, with beta1 in a relatively complex night scene I get:
CPU: 280K rays/sec, ~6.5 rays/sample, 780 samples in 8 minutes (or something very close to those numbers)
OpenCL(no cpu): 290K rays/sec, ~6.5 rays/sample, 860 samples in 8 minutes

with alpha v4 I thought since opencl works can use cpu I would get double(or near the performance) but I got
OpenCL(with cpu): 420K rays/sec, ~6.5 rays/sample, 1120 samples in 8 minutes (so far from double the performance)
I also noticed that it takes quite a bit of time to get to 400+ rays/sec, I probably would get more eventually but it was accelerating very very slow.

Same here on Linux Mint....with opencl hybrid....cpu usage goes to max 21%.
