Bizarre Mesh Issue with All Non-SOS Base Human Cocks - Giant Red Exclamation Point

[IvanVancheskov]

So I'm running into a really weird problem where each additional cock I've installed shows in game as giant red exclamation points. 
It does this for the attachable version, the strap-on version, and the SoS selectable version.
It does this for two cocks that I've installed: TRX - Futa, and SoS Futanari CBBE. 

SoS Schlongs, when toggled for a female, simply don't appear. They work just fine for males, and all creature cocks appear to be functioning as expected.

Is this because I'm running the LE version instead of the SE? I've been extremely hesitant to upgrade to SE because there are a handful of mods that just flat out don't exist anymore. I don't blame mod authors for not reviving a 2012 project to bring it into SE but it does mean I'll loose a bit attempting that.
Would/Can I downgrade these mods to the LE version if that's the case, or is something else at play here?

I've done a complete reinstall of all my SoS, Sexlab, and body/skeleton impacting mods without much luck. I -do- use Vortex to load the mods. 
I know it can be done, I've seen some really good Skyrim machinima porn over the years whose upload date would necessitate LE edition, the question is, what's gone wrong with my install and how do I fix it? I've never seen an error quite like this before. Screenshot of issue attached, any help is greatly appreciated. 

I can post my mod-list and load order if needed but it's very long so I'll leave it out for brevity.

Convert the mod with Cathedral Assets Optimizer (TES5 profile)

Also convert bmp files to something like .PNG/JPG so that we don't have to download it to look at it.

If you are running LE then make sure all your mods are the LE versions.

What you are describing is missing mesh.

If you are using Vortex it should show you if you have problems with a mod.

 

Forget about Cathedral Optimiser - it is irrelevant here.

 

Open up your bmp in paint and save as jpg. Drag the jpg here and place in spoiler tags. Either by using the 'eye' icon above or typing

without the spaces. Do the same if you post FNIS output, load orders any other type of list.

@Grey Cloud Vortex hasn't reported any issues, neither has LOOT. But this is the result.

Looks like an incompatibility issue. I'm probably going to bite the bullet and go and get the SE version of skyrim. It looks like the majority of my mods have either been ported, remade, or have an equivalent anyway. Untamed will be lost but it looks like that's about it truth be told. Oh well. C'est la vie.

That big red warning marker means your missing mesh files. If your wearing something then you need to check the mod and make sure it's installed correctly and that there are no required files that it needs.

It also indicates SE mesh in place of LE. While the file exists, LE cannot read it. CAO rarely helps, the only reliable fix I've seen is to use Bodyslide to convert the mesh. Even Nifskope has failed.

@Pauduan That's what the issue ended up being. I'm guessing most of the LE futa mods have just been deleted or lost. I made the jump to SE anyway. Happy with the choice so far.
