I have never made any kind of custom content, and I was hoping someone could suggest which tutorials would be best for someone who is not that familiar with computers.

What i'm hoping to create is a jetpack that becomes invisible when worn. I don't want to make this a default replacement, and i'm guessing it would have to be visible initially so the sim could equip it.

If anyone knows of a tutorial that would help with this or a suggestion on how I would go about creatingit, I would greatly appreciate it.

You can clone EA's Jetpack using S3OC making sure the box next to the word renumber has a check mark in it, open the clone using s3pe, and then, using s3pe's grid, edit the inUse geostate of the MLOD and MODL so that instead of the number showing there it is all 0's. The inUse geostate is 0x44180715. To get to that portion of the .package just:

1. Click on the MLOD (or MODL) line
2. Click the Grid button near the bottom center of S3PE 3. Expand ChunkEntries
4. Expand [0] ChunkEntries (for the MLOD)
5. Expand RCOLBlock
6. Expand Meshes and then expand [0] Meshes
7. Expand Geometry States
8. Expand [0] Geometry States (this should be the 0x44180715) and change all fields in it *except for the Name* to
0x00000000. Leave the Name line as-is.
9. Click Commit
10. Repeat for the MODL but instead of expanding [0] ChunkEntries expand [1] ChunkEntries
11. After you've changed both MODL and MLOD click Save and then test in game.

ETA: to correct mistake on step 8

Thank you so much for this. I was a little worried about trying this but you've made this seem pretty simple. I'm off to try this right now, hopefully I can get my Superman SIM off the ground and into the air...
where he will most likely do a nose dive into the ground when he lands, but hey we all gotta start somewhere.

It is really simple but I need to make a correction to what I said above.

What you need to do is locate the GeometryState named 0x44180715 as I said but instead of changing the Name to 0x00000000 you need to leave that one as-is and change all the fields below it to 0x00000000.

You will be changing a total of four fields including StartIndex, MinVertexIndex, VertexCount, and PrimitiveCount.

Sorry for the confusion. I'm going to edit my above post so someone doesn't stumble on it and get the same confusing thing. :P

I've been looking for something similar! If you do create this mod successfully, could you pretty please consider uploading it?

I have a question related to this; how do you make other objects invisible in live mode but visible in buy/build? Things that don't have geostates mostly such as decorative objects and whatnot.

Thank you.

I'm not sure if this is actively being updated or if it's exactly what you're looking for but you can use it to make things which are visible in buy/build mode that will turn invisible in live mode:

Thank you orangemittens. I have Buzzler's excellent mod. It hasn't been updated in a while. Regardless, I still want to know how to do this for myself. Any help would be appreciated.

Sorry, but there have been some progress in this regard?
I need for my fairies hidden jetpacks .. And Im terrible in programming :/

Hello,
I followed the directions from Orangemittens and created the invisible jetpack. You can get it here --> http://modthesims.info/download.php?t=521802.
Thanks.
