Problem with material tiling...

[Evil Eddie]

I'm fairly new with Rhino so I've only just begun to experiment with materials. When I use textures for architectual renderings like walls and floors the picture I use for the material is streched over the entire surface, no matter how large the face is. Then I saw "Michas Starterkit4" where the chess-texture used for the wood is really only 4 squares and is then copied onto the entire face. I can't find out why it isn't posible because as far as I can see, I'm using the same options. Then I tried using the wood-material created by Micha on a new suface and the 4 squares are streched over the whole surface. Can anyone tell my why? (I've added a picture of both the old and the new surface, which is equipped with the same premade material)

Re: Problem with material tiling...

If you select an object and open the object properties window, than you find at the roll down menu a Rhino mapping option. Per default each surface has standard UV coordinates. This option tool allow to change mapping type and repeat/offset/angle.

Closed objects like a box has a "packed" texture often, so that not all surfaces show the same texture. The command unpacktexture bring back the typical per surface UV coordinates.

For the checkerboard you have two ways:
- change the UV coordinates by rhino mapping tool
- or set at the Vray texure interface a new texture repeat. The Vray texture UI allow to change the repeat/offset/angle only, not the mapping type like box/spherical/planar.
