hey guys, i'm wondering if anyone can help me with this!
so i'm converting a hair 4t3. bones are assigned, LODs made, etc. i'm importing hair LODs into TSRW and for some reason i can't have BOTH the very high and high LODs. i can import either one first with no problem, but when i try to import the other one it gives me the "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" error. the medium and low LODs work fine. i'm using version 2.0.86.

if anyone has encountered this before and knows how to fix it lmk please!

How high is the polycount? If you have high poly plus morphs, it probably won't work. Even adding morphs to some high poly TS3 hairs won't work. You may also want to try a newer TSRW... but keep 2.0.86. I find that each version of TSRW has it's own short falls, while each may work better on certain other things.

There is also a trick, to import .wsos thru the edit project contents screen in TSRW. Where you export as package. Right click the geom you want to replace, and then click import and import your .wso that way, and see if it works.

I know this is an old post, but you are an actual lifesaver for this. I was getting so frustrated because no matter how much I decimated this mesh TSRW would not let me import anything into High LOD without crashing. But this worked! Thank you so much!
