put a poster on the wall...?

[Ziska]

Is there any way to place an image (like a poster) on a wall (or any other extruded surface)?

I know I can use an image for a fill in 2D or a texture in 3D- but that tiles the image.

Sorry if this has been covered a million times already....

TIA

Use a texture. do not check the 'tile' box. Scale the image (by trial & error) to get it to the correct size.

Thanks, I was afraid of that...

Is this also the only way to get signage into Renderworks? I normally have a lot of logos to deal with and people get upset if the graphics get scrunched....

Hello Ziska:

Model->Create Image Prop.

Uncheck Create Plugin, Crossed Planes, and Auto Rotate to Viewer.

This will create a texture mapped 3D polygon that you can place wherever you want. You can use this for pictures, signs, rugs, etc. If it is created as a plugin you are limited to rotating around the z-axis because it is a plugin.

Dave,

Thanks- tried that too. Another silly question-

How does the image prop differ from a texture?

I still don't seem to be able to laminate it to a curve or other non planar shape.

Thanks,

Ziska

There is no need to use trial and error to scale the texture, if you already know what size you want it to be. The Size field in the Edit Texture dialog is the width of one repetition of the image shader, so you can put 36" in the Size field if you want the texture to be 36" wide.

Alternatively, if you know a particular part of the image is a specific size, click the Set By Image button next to the Size field. In the dialog that follows, the line segment you see can be set to a particular length, so if you know a part of the image is supposed to be 8" tall, move the start and end points of the line segment to match and type 8" for the length. The Size field in the Edit Texture dialog will then be calculated from that.

The Scale field for mapping is only really necessary if you don't have a specific size in mind and/or want to set the texture size by "feel". Or if a particular object needs to have its own distinct size relative to other objects that use the same texture you can override the texture size for that one object.

p.s. This is different for image fills (Kristen's suggestion), which is the way to do it if you only need 2D.

The image prop is texture-mapped geometry. If you choose Crossed Planes the geometry is a group of two 3D polygons. Otherwise it is a 3D polygon. The image prop automates the work you would have to do to get the geometry to match the image's aspect ratio. If it is a plugin it can auto-rotate.

If you want to map to a curved surface, create a texture that has a non-repeating image color shader, apply it to the surface, then use the Attribute Mapping tool to place it where you want. The texture should be given a realistic size for a poster, like a couple of feet wide.

If you have any image editing program (PhotoShop, etc.), you can at least shortcut the trial-and-error scaling. For example, if you want a 24x36 poster in your model, go into Photoshop and scale your source image to be 2"x3". Then you can bring the image into VW and scale it by a factor of 12.
