I am trying to create a couple of items, one of which is supposed to overlay on top of the other, making everything it covers disappear - from a mesh standpoint, this is working great, but I cannot get the overlaying item to display its own texture, the only texture showing is the one of the item underneath, with the overlaying texture showing beneath the alpha areas. Currently, the item underneath is classed as Skin Detail / Forehead and the item on top is classed as Earrings - I had assumed that skin detail textures would be at the bottom, and earrings nearer the top, but obviously I was mistaken. Is there a listing somewhere of the order in which the different CAS textures are overlaid on top one another, so that perhaps I can recategorise them and get it to work?

From this thread http://www.modthesims.info/showthread.php?t=556855 / this tutorial http://modthesims.info/showthread.php?t=540210 I'd think it's the CompositionMethod that controls this.

Woo, thank you PB! The problem was that both were set to 0x00 in the composition method; for future reference, 0x03 is the composition method for skin details, since this wasn't mentioned in the tutorial thread you linked me to.

Can you post that in the tutorial thread perhaps? That way it's more useful for others.

Update: turns out the composition method seems to act more like a shader than a sort order - my items are 3D meshes and they freaked out a little when I changed the comp. method, as you'd expect when changing the shader in the GEOM files.

The entry titled "sort layer" is what gives the game the order in which to arrange the textures - that seems to be purely what it does. I've not figured out the actual numbering system for it, but there seems to be one there. 0x000029CC (copied from boots) composites below 0x00003E80 (copied from a full body outfit). I suppose each type of item has its own number for its own texture layer, but one would have to look at a lot of different items to be sure.

Hello, here is some info about sort layers that you might find helpful.

I've not had much luck with the Sort Layer - once tried to fix a long top that got overlaid with some (not all) bottom textures, and the Sort Layer didn't help. IMO something else is going on in at least some cases.
