I have made my own lightmap because the one that UE4 was not to my satisfaction, uh, statisfactory(?).
What I mean is that I was not happy with ‘lightmap density’ so I made my own!
However, I am having a weird problem where I cannot make it work. Well, sometimes.
Okay, let’s see, it has 3 UV maps:
- The one for the texture.
- The lightmap UV that I made.
- The lightmap UV that UE4 generates.
So, I set the Source Lightmap Index to “1” and the Destination Lightmap Index to “2”, with Generate Lightmap UVs unchecked.
It works fine the first time. However, if I exit and open it again and make it build the scene, then it goes back to the the generated one.
When I go to the, uh, “Static Mesh Properties”, it’s still set to “1” and “2”, like I did before, and if I press Build again, it just shows the generated one, again. So I have to go and set it to “0” and back to “1”, however that makes it crash, sometimes.
I looked around to see if somebody had the same problem but I am not sure if it’s the same problem as this. source lightmap index reset to 0 - UE4 AnswerHub
Thank you for reading this and for the help!
