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.

My solution about this problem is: try another texture. Yesterday I got another street texture of a colleague and this one seems to be almost moiré-free. A full resolution version of this image can be found here. With Luxology the challenge of grass and water seems to be solved. Street materials are in my opinion, stil very difficult to get realistic.
Hi Louis,
Try these texture, and let me now if it solf the problem!

Louis,
Yes, and here is an pattern map.
Units master, Size locked and x=3.00, parametric, bump about 50
I often find moiré can be elliminated by reducing the resolution of and softening the patternmap.
