Re: YafaRay rendering plug-in
@Puybaret

The version 1.4.4 fixes some kind of shadows that could appear on some complex flat surfaces with the version 1.4.3 of the plug-in, like on the door of the dishwasher in the following image.
The problem is not seen with the Ambient Occlusion lighting method but persists with Path Tracing.

Ambient Occlusion_Shadow Bias=0.005 - Ray Min Dist=5e-05 (auto)


Path Tracing_Shadow Bias=0.005 - Ray Min Dist=5e-05 (auto)


Same effect with the parameters: Shadow Bias=0.0005 (auto) - Ray Min Dist=5e-05 (auto).


This is actually a tradeoff on the parameter I changed in the previous version to avoid clear lines at the ceiling border. A few clear pixels may appear a little more in version 1.4.4 but this unwanted shadow line won't appear on this dishwasher (and other 3D objects, I hope).
With the SimpleRoom file, I always get this result.

Ambient Occlusion_Shadow Bias=0.005 - Ray Min Dist=5e-05 (auto)


Ambient Occlusion_Shadow Bias=0.0005 (auto) - Ray Min Dist=5e-05 (auto)



What could make the faces of a mesh visible in indirect rendering (Photon Mapping)?
