Interesting info there :) thanks for that. What do you do in 3dc to invert the green channel?
John
You can do 2 things
- convert the green-channel "by hand" (this is what i mostly do): Using gimp, load-the normal-map; then use the colors->curves tool, select the green-channel and turn the ramp-up into a ramp-down.
- or (which seems to do the same): in 3dcoat's Edit->Preferences, choose "Maya" for the normal-map-export item (see image. the default is "3ds-max, lw"). This probably the easiest way if you are using only 3dcoat/poser.I use the lengthier approach with gimp mainly because i want to use the normal-maps from within blender, too, and for that i have to invert the red-channel, also, and there is no equivalent option in 3dcoat for that. So, since i have to do some manual adjustments on the anyway, i do them both by hand. And besides, after an update to 3dcoat (which happens quite often) the preferences are back to default and i have already forgotten about it...
Cheers man :) that is extremely handy to know :)
