How to Auto-Generate Lightmaps for my Blender model?
SPOILER: Im new to Game development and 3-d modelling so be patient with me :P
So the meshes i made in blender when exported to unreal, were becoming "black" in color when i built the lighting. The problem i found was that i wasnt addding any lightmaps to my mesh. (i had no idea what a ligthmap is) I searched around the net to find out how to make/add light map to my mesh and found the solution on how to do it in blender. But i also found another video: https://www.youtube.com/watch?v=UnUn4nRoh-E in which unreal can auto-generate lightmaps for your meshes at the time of import
Here is my test mesh
When i import this mesh into unreal as an fbx i get the import menu in which there is a ticked checkbox that says "Generate Lightmap UV's":
But the mesh still doesnt have any lightmaps and still gets dark when i build the lighting, however it worked for the guy in the video (unreal auto-generated lightmaps for his mesh): Here is a SS of the blank lightmaps for my test mesh after exporting to unreal(both the channels, 0 and 1 are blank):
What am i missing here? how do i make unreal auto generate lightmaps for my blender mesh NOTE: no extra settings have been made for the blender mesh, i just opened it and extruded the faces of the cube in random directions and exported it as fbx Thanks for sparing time to read! i would really appreciate some help asap
I think you forget create UV0 in Blender. The geometry that you want to import into UE4 should contain UV0.
Use this tutorial for create UV0 in Blender.
And try again to import the corrected model.
