Hi,
I have a separated objects that has their own uv's.
i would like to know how can i merge all the UV's and make ONLY ONE UV so that
all objects will have the same uv.I want all uv's to be overlapped on each other because i don't care.
can i achieve this with 3d coat?

Thanks.

    well I think there is something missing in your explanation.

    If you don't have a problem when the uvs overlapp then why don't just combine all objects to one?

    1 uv == 1 object

    or

    1 uv layout == 1 texture == 1->n objects

    or

    1 uv shell == 1 object -> n copys of the same uv shell overlapping == n objects

    So it might be good to explain a bit more why you want to do this and that might bring some light into this

    Hi,
    thanks for the explanation.
    the reason i want to do this is because i want to reduce the draw calls in unity game.
    and for the overlapp i don't care because i have a rock texture that cover the entire uv and each
    object feeded from the same texture.

    Each separate object creates more draw calls. So, you need less objects.

    yes, you have to combine those objects to a single one and assign the material you want.

    unity comes with an combine children class i guess
