Yes, I did test that. In fact, the image I shown is rendered under a unbiased condition. Also, Russian Roulette is enabled in the image that I shown. I have set BOUNCE_DEPTH to -1(which makes my renderer to ignore bounce limits).

Have you tried setting FACTOR_CUT_OFF to 0 (introduces bias, LuxRender is unbiased)? Have you tried excluding techniques like Russian Roulette, to see where the culprit may be?

Or maybe you cant get it to look the same, like the whole image gets to light to get the centre the right brightness, then maybe some angle calculation is not the same.. just some ideas to try out | |

Edit in some code
|
| Jan 22, 2016 at 15:03 | comment | added | Mary Chang | I have edited in some code. Hopefully it helps. Also, here is the whole repo. More code could be found here. (Please use the "dev" branch. It's where all the new codes are.) bitbucket.org/Seanstone5923/simpleray5cpu. OK, I'll fix the camera as soon as possible. | |
| Jan 22, 2016 at 10:20 | comment | added | David Kuri | Still it might be that you are using a different photometric quantity somewhere, that your tone mapping is still different despite Gamma 2.2, that you're missing a pi somewhere, or any other reason. It's hard to tell, please give some more details about your shading, show some code etc. Besides, the camera is not the same in both images, you might wanna adjust that too :) | |
| Jan 22, 2016 at 9:49 | comment | added | Mary Chang | Pretty sure, because and Lux uses diffuse IES data on light sources by default and I only support diffuse material. Also, both light sources have the same strength/color of 6.0. | |
| Jan 22, 2016 at 9:27 | comment | added | David Kuri | How sure are you that the light source is parameterized in the same way? | |
