So I'm trying to use a projected texture from camera on a grid as a matte object. The texture has an alpha but when used as a matte object it will only use the grid geo as the matte. Is there anyway to use the texture applied to the grid as the matte?

What decompression software does that need? I've never seen that file format before. Is that for linux? Can you compress it for mac or windows?

no compression
it's a regular .hip file you need only houdini to open this
created on H9.5.231, WinXP 32
do you have any problems opening it?

Got it. There was a weird extension added when I tried to download it on my mac. On linux it's good.

The texture is not matting out during render. Only visually in viewport.

here is the render from that file, i don't know if it's what you want, but it's matting the background objects by texture alpha
