Noisy reflection I have a question about the reflection on the wall. There is a wall and an object. Wall - glossy colored ceramic tile, without figures. Tiles should be self-colored and smooth, but a reflection on the wall looks like a single points of light, or as noise. I want to get a smooth reflection. How do I make a reflection without noise? Sorry for my English. Example:  http://www.mediafire.com/view/sp7rc8azzx7aed6/03_copy.png Used texture:  http://www.mediafire.com/view/6i16iuwuz1jojbo/3.png |

Re: Noisy reflection The easiest way to reduce noise is to create a twice (or more) larger image and reduced it once the image is computed with an image software. ---------------------------------------- Emmanuel Puybaret, Sweet Home 3D creator |

Re: Noisy reflection The twice larger image and then reduced looks much better. Thank you. For comparison - original:  a twice larger image and reduced:  |

Re: Noisy reflection Hmm... that may serve as a workaround, but when you're rendering an HD image which takes several hours to complete, the last thing you want is to multiply the rendering time by 4.  ---------------------------------------- If a long walk every day were healthy, mailmen would be immortal.  |

Re: Noisy reflection As said before, it was the easiest way. The other way would be to increase antialiasing with the following parameter passed to the JVM (see also this message): -Dcom.eteks.sweethome3d.j3d.PhotoRenderer.highQuality.antiAliasing.max=3Rendering will go slower but not as much as computing a larger image. ---------------------------------------- Emmanuel Puybaret, Sweet Home 3D creator |
