Subdivision and a texture surface hatch

[JMR]

Hi all,

 

How do I control the direction of a (texture) surface hatch when applied to a subdivision? Attribute mapping doesn't work and I don't see any controls in the OIP?

 

It doesn't matter if I select the whole subdivision of just one face.

I have to check, but this seems odd.It might require using the split tool and multiple textures.

Ok thanks. That answer was exactly what I was afraid of...  🙂

 

As a workaround I can change the subdivision object to eg. a 3D polygon and then map that. However, having to do so doesn't make any sense - what's the point of a subdivision object if it cannot be mapped=rendered properly?

 

...Or am I missing something obvious? Or is this something that has been completely overlooked?

Keep in mind that Subd and textures are sometimes not the best friends. Mapping is getting better but every now and then, depending on how a specific texture pattern runs...well...I am glad people are looking into it.

if you convert, keep a copy of the subdivision for future edits. I'm not an engineer, but I can see how mapping directions on faces could be an issue.

I cannot apply the mapping to a subdivision object even manually, that's the problem. Automatic operation would be great, but now I just want access to mapping controls.

I think I've had the same issue. I generally use simple procedural textures. I recall trying to get a wood grain. but I could not control the direction, so I modified the design.

It's a bit of a cheap rendering trick but you can always use the extract tool to pull a NURBS Surface from one of the faces. Then you can independently control the texture on just that surface. You may have to adjust the position of the NURBS surface slightly to avoid Z-Fighting. But everything should come out fine in renderings.
