can we import datasmith without creating automatic lightmap ?

can we import datasmith without creating automatic lightmap ?
can epic add option for users who want to use full dynamic lighting
and give control in importing option to select or deselect lightmap option ?

There is a new feature in the Unreal Engine/Datasmith 4.22 release that you may find helpful:

  • Specify a custom Lightmap UV channel to be used - Datasmith previously auto generated Lightmaps for all objects, resulting in 2 extra channels no matter if users have created their own Lightmap UVs. The new Datasmith Attributes modifier allows for overriding that behavior on specific objects, typically the ones that have been manually Unwrapped for Lightmaps.

if your goal is to prevent lightmap unwrapping for saving import time, it is not possible now but in 4.23 this will be possible.

Hi, is it possible now? I don`t see such option when I try importing a file

We postponed the option to disable lightmap unwrap to 4.24, sorry about that !

it will completely disabled
or only in importing with datasmith

i hope someday we baked in ue4 without lightmaps (with sparse or voxel probe tech)
