locking material images in position

[David Johnson]

I made a block for a sign on a fence that needs to be placed every 50 feet or so around the perimeter of the fence.

The sign is made from a 3dface with dimensions of 12" x 28" with the material made using a photograph of the sign.

The image looks perfect when rendered from the drawing the sign is made in.

When I insert the block into the fence drawing and render it the image shifts.

It looks perfect in the fence drawing when viewing from autocad with shademode set to realistic; and in the walkabout window.

I edited the x offset of the image for the material in the fence drawing to get it aligned in one view, but when I copy the sign around the fence the image has a different offset for each sign.

The image is offset again when I change views.

Can the material be locked to reference the insertion point of each block so it doesn't shift?

I am hoping I don't have to make a different block and material for each sign location and view.

Have you used mapping?  If not, try going back to the original sign drawing and using Mapping to fix the texture coords. to the object.  I recommend the Quick Mapping button on nXt's Materials tab-- a Planar or Box option will work fine for this.  You may need to reset the Offset in the material def back to 0.0.

the mapping worked.

thank you.

Decals should work for this as well.  They're used all the time for this sort of thing.  Something silly went wrong in the process.

I would use decals to make signs rather than materials.

[George Ioannidis]

Ditto.

I tried using decals.

I have two signs, an ownership sign and a safety sign.

The ownership sign worked as a decal, the safety sign didn't.

I am still using a block for these signs.

In the block drawing the safety sign renders fine.

I attach the decal to the sign in the fence drawing the safety sign doesn't work.
