Exporting an Object as *.fbx with multiple UV channels for importing into 3DS Max

[anewbieuser]

Hi I am new to Blender, I am trying to export an object with multiple UV channels so that I can import it into and use it in 3ds max. Please see the snap shot attached. When I import the fbx into 3ds max, I cannot see all the UV mappings in different channels which I can in Blender. Is there anything I can do to fix that?

Welcome …

i’m not sure about the capability of FBX with multiple UV channels… at there seems to be som issues with tis if you search on the tne

For example only usign two ??

Wrong UV after .FBX export in Blender 2.8

yeh as of now there is no manual way to re-arrange blender UV maps. In UE4 if you import as .fbx (grouped) it will only pick the first 2 UV maps, if non-grouped it will keep all the UV maps but your objects will be seperate (usually you want to use .fbx to pack multiple .obj’s into 1 and keep their respective UV maps). There is an add-on called “Asset Creation Toolset for 2.8” which, has many cool tools, allows you to change the UV name/order: https://gumroad.com/mrven?recommended_by=library#

but then it also seems to be fine here:

Exporting FBX/OBJ file with multiple UV maps--only active UV exports correctly

To my knowledge OBJ is not capable of storing more than one UV map - that’s a limitation of the file format, not of Blender. So, OBJ is “out” for what you want to do. FBX, however, should be perfectly capable of saving more than one UV layout and indeed it seems to work just fine with your file. After exporting your file to FBX I see this e. g. after importing the FBX into MODO… [image] … and this is the FBX import dialog from 3D Coat - again showing all three UV layouts: [image]

Also i seems to be a bit weird how tu use mutliple UV’s in MAX attaching a UVW map modifier for every channel ??

thanks for the prompt reply and welcome. I tried deleting the other UV mapping thatI do not need and export to fbx then import to 3ds max again, but the remaining UV does not show up as shown in Blender when imported into 3ds max… I wonder why.
