Hey guys,
Good morning. I am trying to get the attached jpg to display on the curving surface in the attached Rhino file - like a billboard but not flat.
Trying Decal but it doesn’t seem to have an option that would work. Any thoughts would be appreciated. Thank you.Hi, I had the same problem a couple of weeks back, use _Picture (surfaces menu) then bend to suit.
Is there no way to use decal to apply it?
well, another way would be to lay it on as a texture. Your receiving surface has to be a proportional size to your jpg.
More specifically? When I layed it on as a texture using the Materials tab/ create Custom material and then attach the image to Color as a texture, it distorted where the surface curves.
I’m sorry, not sure what’s happening there, I don’t get that. You’ll have to wait for somebody more knowledgeable.
Hi Cosmas - the problem is that the UV of the surface is compressed in the middle, stretched at the ends - here is a checker pattern applied:
To get the UV evenly distributed you can do a couple of things -
Just Rebuild the surface to a lot of points. - Rebuilding evenly distributes the UV space. However it makes the surface more complex in this case and inexact if that shape is critical, so…
Rebuild a copy of the surface and use the copy as a custom mapping object on the original.
In this case, it looks like you also need to split that surface on the vertical isocurves and rejoin into a polysurface before applying the custom mapping object - that looks like a bug, to me.
