What problems does mgmosaic have with insets?
I am trying to work with high res insets inside a low res image. When I create
the clip texture (with mgmosaic) it looks like mgmosaic simply did izoom to my
low res image to be at the same "resolution" as my high res image and then
doing the mosaic as usual - Since my low res image is VERY BIG I need a HUGE
disk for this clip texture. What I assumed to see is that level 0 will only
have the high res areas and only lower levels will have tiles from the low res
areas.
Am I missing something, or is this a bug in mgmosaic?
