Texture across multiple objects

[Kevin McAllister]

Is there an easy way to map a texture across multiple objects so it feels like its a continuous image? Imagine something like one of those changing billboards where all the individual strips make a complete image.

Kevin, here's a thought: what about one large object with the texture and then a bunch of smaller frame-like hollow objects directly over the the first?

From the VW2010 Help:

Use World Z For Origin

Sets the texture?s Z origin to be relative to the world Z origin, rather than to object space. This allows seamless texture application across multiple layers for all mapping types. Multiple objects with this parameter enabled render seamlessly along the Z axis.

Align Selected Mappings

Aligns the texture mapping of multiple selected objects, giving them the appearance of a shared texture. Multiple objects with this parameter enabled use the mapping parameters of the first selected object, and the texture appears seamless across all selected objects. The shared mapping depends on the objects currently selected and can change with a different selection of objects. This parameter is available for planar, cylindrical, and spherical mapping only. It is not available for perimeter mapping or when Auto-Align Planar Mapping is enabled.

Set the mapping to Planar, Turn on both of the above (and turn off Auto-Align if necessary) and you should get what you are looking for.

Thanks for the advice. I will give it a try.

Looking to use (for a long time...) the Align Selected Mappings check box in the Object Info Palette. 

Used GOOGLE to search the Forum back to 2010 ... No such luck on how it actually works

Created a test file with two textured extrudes and tried as many combinations in the Object Info Palette as I could think of.

 

 ¿   Align Selected Mappings check box appears to ALWAYS be greyed out - What is the magic combination (VW_RW Designer 2020) ?

 

¿ Anyone have any thoughts ?

For fine detail, make use of per face texturing and adjust mapping individually

Have not needed this for a while, but thought I would try this cheat again.

Mapping to faces of several disconnected objects by converting them to a single object.

 

Back "screen" shows full image texture on a single surface.

Foreground objects have same texture mapped to extracted faces:

• Extracted the front surfaces (created 3 NURBS surfaces)
• Connected them w/ 2 lines on layer plane.  Extruded the lines .001 units.
• Convert the extrudes to NURBS surfaces.
• Add solids - creates a single object from the 5 sources.

Apply texture > Plane mapping. Orient as needed via offsets.

I'm pretty sure you can omit this step since Solid Additions don't need to be contiguous. But otherwise good approach 👍

 

You can even then delete the object used for the plane mapping from within the Solid Addition, and the mapping should be retained for the other objects.

[Benson Shaw]

I just tested. For this one, I think the connecters were needed. Middle flat surface accepts texture with different rotation. ???? Switching normals no help. Same with Shell the faces as Solid addition. @Andy BroomellDid you make this one work with only the SA?

 

I have had success with Shell. Extract the multiple faces, then Shell them together at zero or vey thin depth. The Shell, similar to the Solid Addition, is a single, but non contiguous, object which can take the texture as one big image. Didn’t work in this example. Maybe flat to curve is problem.

A mapping cheat….I should have known…:-)

Question ?

 

¿ Is this a bit complicated ? - Try extruding several items at one time ... (See attached)

Good if all are from same extrude command.  But also need solution for contexts where surfaces are not from extrudes or from same extrusion.

This one I traced a poly along bottom edges, Extrude down, Convert to NURBS surface, Add Solids
