I am using the SteamRoller script available for download over at ScriptSpot and it is both a life AND time saver! Highly recommended.
I am having some issues with flattened and uwrapped channel info not showing up in UE4. Some meshes are just fine and I see the flattened and unrapped lightmap information in UE4.12.5 just fine. On the problem meshes, I see no flattened and uwrapped channel info even though I see this info in 3ds Max. In Max, diffuse maps/materials are on channel 1 (0 in UE4). When I use the SteamRoller script, flattened and uwrapped information is on channel 3 (2 in UE4) in the Max dialog. This works just fine for some 3d models without a hitch. On the problem meshes, there is no flattened and unwrapped information on channel 2 (3 in Max/SteamRoller) or any UV information whatsoever. Why does this work on some meshes and not on others? Some of the 3d models are not “dumbed down” - saved as meshes or editable polys in Max. Does this affect what the script is doing? I thought exporting to FBX removes any information that is in the modifier stack on models still being modified.
Please see attached screenshots.
Your help and the help of others is greatly appreciated in advance. THX
