Hi !

Mapping is giving me headaches lately : any attempt to tile on planar surfaces will produce crazy results :


I disabled realscale of course, and tried "surface", then "planar" and even "box" mapping, but it always produces this awefull result
Her's the files to replicate the bug : https://smc2.box.net/shared/static/daqofbtva5.rar

The "ghost" bug with single surface SSS is still there too.

Cheers,

If you look at your textures (in the plugin Material Editor) you will see that they are not tiled; check the Tile X and Tile Y boxes to make them repeat.

Holly tiles !

I never realized there was these buttons.
What 's the point in their existence anyway ?

They exist in order that you may either tile, or not tile, your textures.

So thus far you were slapping every material onto Geometry "as is"?
Don't worry I'll not tell it to anyone...

Hey ! Come on guys !
I'm not THAT stupid !
I use tiling all the time ; either from the definition of the material, or in the Rhino mapping parameters.
What I don't understand is the interest of having a "Tiling/OFF" toggle when you can do just the same by setting the U and V values to 1....
I mean appart from making me look silly in the face of the world ?

Decal masks, for example. If you set U V values to 1 the map still tiles beyond the "projector" or mapping gizmo to the infinite.

Sorry Olivier, I answered that question the only way I knew how. As Fernanado says, where the tile value sets the texture size relative to UV space, it is the tile on/off switch which determines whether or not it will be repeated. If you are wondering why Rhino 'shoots' the edges of a non-tiled texture off into infinity, as seen in your screenshot, I really couldn't say. If you rendered that plane in Maxwell, you should see that the grass texture only appeared in the mapped space, with the untextured material showing elsewhere.

Sorry Olivier!
I have to admit that I didn't read carefully and thought you were asking why there are the Tiling-Controls inside the Material-Editor at all.

Ok, this is all starting to make sense.
I realize I never really made decals in the way they are supposed to be done.
I always used a surface mapping with tiling set to 1 on a surface, and then placed that surface as a "sticker" on a bigger surface.
Anyways, this leaves us with a nice fat display bug in Rhino when used in conjunction with Maxwell material meant not to be tiled, doesn't it ?

I guess I'll post this on the Rhino NG.

No, it's not related to the Maxwell plugin, this is just how Rhino works. You can produce the same effect with a Rhino texture (in V5) if you check the 'Decal' option.

Ok, Ok..
All this makes me wonder why Rhino bothers with decals since in fact you can get the same effect with the "no tiling" trick...
