Requirements:
- A Multi-PT mod, of course
- Either FOUR or EIGHT custom PTs, depending on the mod you're planning to use. One less custom PT is acceptable, if you're planning to use the Maxis Default PT or a Default Replacement as well.

Preparations, part 1: Get the GUIDs (See picture ->)
- Double-click the .package of a custom PT, or Right-click the package and select "Open with SimPE"
- In the Resource List, find and click the OBJD resource
- In the Plug-in View, find and copy (to a piece of paper) the GUID of this PT.
- Repeat the above steps for each custom PT.

NOTES:
- You do NOT need to do this for the Maxis Default PT or any Default Replacement, because they always use the same number (0x2E17B9FC)
- If you're planning to use the PTs with my own special Multi-PT mod and Alien Experiments v1.7 or better, you also need to be sure that you have equal numbers of male and female PTs, AND you must know which GUIDs are male, and which are female.

So now you have 4 or 8 numbers, each one looking like 0x########. The number for the default PT (or any default replacer) is 0x2E17B9FC, for example. We need to convert them to something we can use...

Preparations, part 2: Convert the GUIDs to Little-Endian
- You need to break each GUID down into a Little-Endian sequence. Which means we divide the eight digits after the x into four groups of 2 digits, like 2E 17 B9 FC, and then we make the groups switch places so it looks like FC B9 17 2E.
- Do the previous step for each of the custom PTs you have.

Checking: So far, everything was rather simple, but it's very important that you now check if you have everything right. Depending on what Multi-PT mod you use, you need to have either 4 or 8 Little-Endian number sequences. And if it's for MY mod, you need to be sure that exactly half of them are male, and the others female, and also you need to KNOW which ones are which.

Now comes the somewhat more risky part: editing a mod in SimPE. If you haven't done this before, you may want to make a backup of the original mod first, just in case you blow it and need to start over. I hope to make this manual clear enough that there's little risk of this happening, but still...

Double-click the Multi-PT mod, or Right-click it and select "Open with SimPE". In the Resource List, you'll see a line "NPC - Get Alien Dad - NID". Click that line, and look at the Plug-in view (picture SimPE 001). Here's where modders do their scary work It's not a lot like making a peanut-butter and jelly sandwich, is it? Anyway, let's continue...

Identifying the lines we need to change
Looking at the next picture, you'll see that a number of lines have been marked with a color pen. Lines of the same color use the same GUID. Regardless what Multi-PT mod you're looking at, you'll always find four or eight of those groups, and THESE are the groups that we need to change, to make it use our PTs!

The tricky part: actually editing the mod
- Select the first line of one of the groups
- Look over at the right... and you'll see the Little-Endian version of the GUID for that group in the first four fields (underlined). That's why we needed our preparations: so we could replace those numbers with our own!
- Click the first of those fields (purple underlined) and enter the first part of one of your Little-Endian numbers. Hit the TAB key, and enter the next, until the whole number has been done.
- Repeat the previous steps for the other two lines of the same group, using the SAME GUID.
- Now do the same for ALL the groups in your mod. But remember: if you're using MY mod with Alien Experiments, you *must* enter the male GUIDs in the top half, and the female in the bottom half of the mod.
