HI:
I used the version of the tracking camera mode, I saw the tutorial that your team sent to others before, you can map shadows through the bulletin board, why is the shadow I mapped is pure black, and the color you map is more natural, is there something wrong?If you know, please answer for me, thank you in advance！
（Figure 1 is from you, and Figure 2 is mine）
Hi,
This could be because you only have one light source and no ambient lighting, such as a skylight, as used in Figure 1.
Notice that the shadow here is completely black in Figure 2:
While the shadow, in this case, is not fully black because the ground is made of a somewhat reflective material:
Note, that Billboard's material is not reflective at all.
Warmest regards,
