Decals on Irregular shapes

[David Austin]

What is the best way to put a decal on an hour-glass shape?

[Roy Hirshkowitz]

You only have two choices of projections-- try both and see.  Neither will be perfect, but one may be a little closer to what you're going for.

I believe it is time spherical decal mapping be introduce, unless there is a way to do it in AR3/4 and have nxt see it and render it thus.

[Chas / Aug Posekany]

The only way I've found is to convert the decal into a material to the proper scale and use material mapping to place the decal.

I did a set of billiard balls in this way, was cumbersome to set up but renders fast and looks good.

[David Austin]

Yes-I created a material and applied it. Cumbersome but it eventually worked.
