Texture converter issues when converting to RDR2

Hi, I have some trouble when trying to convert textures to RDR2 format. It works fine with ytd with not too much textures in it, but when there is a lot of them (more than 800 for example) the converter just doesn’t work. Is there a way to fix this ? Thanks for your help.

PS : I’m trying to edit inventory_items.ytd.

Edit : After some testing 410 textures seems to be the limit. Hope we can increase it.
