UV Emmission Problem

Gidday All,
I am sure it may be a UV problem... but I am not sure why. I have a Butterfly that is "badly made triangles" but requires no opacity mask.
I also have a plane that has quads and requires an opacity mask.

I have an emmitter on a diffuse material that the emmission only show up on the plane...

Any ideas... renders fine in Maya and diffuse part of map works fine too.

Thanks in advance for any suggestions

check Your normals :) those triangles doesnt look good in terms of modeling.... try to clean up the model...

Is there anyway to make a two sided surface for OCTANE Render Material.
I know I can duplicate ploys ... reverse normals and do it that way but then I just doubled my poly count

Thanks

I'd really like to see a 2sided material as well or at least an option to flip normals in octane...that is a poly issue though so maybe we shouldn't open pandora's box just yet, or else a million modeling requests will come thru.
