I just modeled this object that I'm going to be using in a bathroom. I tried importing it into Unreal Engine but when I do the mesh becomes black after light building. People said I have to create a UV lightmap so I looked up tutorials but first I need to UV unwrap twice since Unreal Engine takes the second UV as the lightmap. I have no clue where to start UV mapping since the urinal part dips in. I understand the top sensor part since its just circles and spheres, but its the other part I'm confused about.

  • $\begingroup$ First, just try to make any flat surfaces one face. select one face on a flat surface and hit CTRL + SHIFT + ALT + F and then dissolve the selection by hitting X and then dissolve faces. This will make some things less complicated. $\endgroup$ – Hendriks3D Jan 8 '17 at 20:14
  • $\begingroup$ Ok thank you for that it did clear some room up and removed some vertices for space in the game. However, I still need help on what corners I should mark seems so I can unwrap it because of the part it dips in. $\endgroup$ – HighKyle Jan 8 '17 at 20:18
  • $\begingroup$ That would be easier if you hadn't used the bevel modifier yet. $\endgroup$ – Hendriks3D Jan 8 '17 at 20:19
  • $\begingroup$ I haven't yet. I only beveled where it curves like this: gyazo.com/e2f87a90e9892bce2cc2c15db3ff1c87 $\endgroup$ – HighKyle Jan 8 '17 at 20:22
  • $\begingroup$ You should be read the The tutorial of UV Mapping it may can help you. And you can look more and read more many tutorial in there, thanks $\endgroup$ – M. Mansyuru Adin Nov 8 '17 at 10:03

Never mind everyone I did a UV Smart Project and it looks like this:

Would this be good for making the light map and stop the overlapping?

  • $\begingroup$ Can someone answer my question and I won't have to make a new answer for it to be at the top of the forums. Just a simple yes or no. Can a smart UV project be good for lightmapping and stop my mesh from being black when I build lighting\? $\endgroup$ – HighKyle Jan 8 '17 at 23:53
