Hello
This morning I tried the new version 1.1.240.1
The Little export UVW problem was my fault: the import option UVW coordinates, was unchecked.
I think is a little problem with the opacity value "d"
Now all materials have the opacity map
But in 3DsMax all value is at 100 ! result everything is transparent
and i need to disable or change the value to 0 to have opaque texture
(i have take a look in. MTL and all "d" value = 1.000000)
edit : i have check in 3dsmax the option "force black ambient"
and that work ,the opacity is good render
