Some modded poses created in Blender are able to be paired very quickly using Lighty Lights tools. Follow these steps:
1. Enter photo mode.
2. Select the pose you want for the first character dummy (either in the photo mode dropdown menus or via QSAT).
3. Select the corresponding/paired pose for the second character dummy (this can be repeated as needed for poses made for more than two individuals).
4. Using the Lighty Lights tools (in the PM tab), position one character in the final position in which you want them to be.
6. Scroll back up in the same (PM) Lighty Lights tab, and select the next character you want to match in the pose from the dropdown menu.
7. Return to the clickable entry saved in Step 4, and then click it (i.e. the entry for the first character whose position you set). This should snap the second character, selected in Step 5, into position and align them correctly with the first character dummy.
8. If any micro-adjustments are needed, you can use the PM tools to manouevre the dummies as needed for a perfect fit.
9. Take photos!
