Today I tried to render an image with some street materials. One material gives a moiré-effect (see image). I tried to increase the anti aliasing quality, unfortunately without any result. Does someone have a solution for this?
MicroStation v08.11.07.74. (Luxology) Antialias filter: gaussian Antialias samples: 254
I made some good experiences wenn I change the isometric-perspective into a camera-pespective with a lower camera viewpoint.
The less logical solution is editing in Photoshop.
Hi,
If you either post your dgn to our ftp site or emai it to me I'll take a look. You can also modify the Shading rate for the material which is in the Material Shading effects section. If you lower this number it will increase the antialiasing which occurs for rays which hit just this material.

in older versions there was a MipMap (or Multilevel) Texture Interpolation which usually helped in similar situations, it produced slightly blurring on texture. this was removed since introduction of Luxology, not sure if it is now set as default method, but you could either simulate it in PhotoShop or simply increase AA in Luxology (which, of course, takes time)

Hi there, I think moiré is a general effect from overlaying meshes which do not match together,one mesh the floor, second mesh the resolution of the rendered image, I would try to make the stones much larger or the resolution higher to minimize the effect.
