I'm trying to export some texture maps as pngs. Some of them should be 16 bit and some should be 8 bit, but although I changed them in Image -> Mode -> 16 bit/channel. The exported image still says 32 bit, i can only get 8 bit by checking the "smaller file option". How to export them in the bit I need? please help

Just different conventions for indicating bit depth - bits per channel or bits total. 8+8+8+alpha=32.

The "smaller file" option gives you 8 bits total, indexed color.

When people talk about "8 bit/16 bit texture map" do they mean total or per channel? Kind of confused here, in the original tif. file it says total 8 or 16. I'm just trying to convert the tif. to png. or change colours but otherwise with original everything but not sure how to do that

That would normally refer to per channel.

In Photoshop bit depth is always per channel.
