Getting texture to show on both sides of a plane?

RenderPretender

I'm using a beach blanket (Iray) in a scene, but the texture is only showing in one side. One can see that the underside of the folds is gray. Is there an easy way to replicate the texture on the underside?

I think you need a two sided shader (maybe nVidia vMaterials or DAZ Uber IRay supply one) or the surface modeled so the surface UVs have normals pointing outwards on both modeled sides.

For Iray there is this product.  https://www.daz3d.com/oso-janus-double-sided-shader-merchant-resource-for-iray

It does go on sale now and then too.

With a regular plane primitive, the same texture shows up on both sides of the plane - that's the default behaviour. Your beach blanket must be specifically set up not to work that way, Maybe the back is a different surface. Maybe it's not UV mapped at all. Hard to say without more information, which beach blanket prop is it?

yeah that is not normal behaviour for a single poly thickness plane

I suspect it is a flat cube with different UV mapping on the underside

look at the UV view for the surfaces

Oddly, the texture shows up on both sides before rendering, but in the render, the undersude under the folds and wrinkles is gray.
