Re: Light cut off problem when using Bidir and Metropolis. How to fix?
I tried enabling the auto smooth option under the Object Properties > Normals section, no change. Note: For time being, it's not implemented for the latest Blender versions - only works with Blender 2.83 LTS :!: Bypass - Use Edge split modifier. auto smooth alone should work, only custom normals ar...

Note: For time being, it's not implemented for the latest Blender versions - only works with Blender 2.83 LTS :!: Bypass - Use Edge split modifier. I tried the 283 version of blender to get the smoothing to work. But unfortunately this doesn't affect the end result. The artifact visible on the top ...

Re: Light cut off problem when using Bidir and Metropolis. How to fix?
No, I didn't, I see now the top circle artifact reflected on the sphere. I will check. It may be some kind of precision/limited color resolution problem: your "room" is a sphere too and normal interpolation may be a problem (for instance, does it happen with a cube too ?). I tried enablin...

Re: Light cut off problem when using Bidir and Metropolis. How to fix?
When the scene is contained in a cube instead of a sphere the artifact is not visible. Tried with several cube room sizes and nothing. But I can't be sure if it's not there 100%. To me it looks like it might be caused by the indirect light reflected from the metal ball somehow. Not exactly because t...

Re: Light cut off problem when using Bidir and Metropolis. How to fix?
I knew that using mesh-lights is not super efficient but, being equivalent to using the same number of lights as triangles... that I did not expect. :shock: I wanted a sphere light for this scene so that it sends light in all directions. I did not check if a point-light could do that. Also I was not...

Light cut off problem when using Bidir and Metropolis. How to fix?
Hello, I am new to Blender and LuxCore. When trying to render a scene with LuxCore using the Bidir Engine and Metropolis Sampling... A Light cutoff artifact appears on a Diffuse Background Surface visible in a specular reflection. I made a comparison render with the Path Tracing Engine and it shows ...
