How to load all props from GTA DLCs

Can somebody tell me, how to add props to FiveM from GTA DLCs?

You can check how i made it for the hospital props in this release. Its the same way, you need to extract the files with open IV and to stream them to your server. I made it for the hospital props but its the same logic for all the dlcs. Hope it help. [Release] Hospital props

To be honest ive put this in but you still fall through the floor at pillbox hill, I can not find a fix for this anywhere, I have also tryed bob74_ipl but still dosnt work

Im looking for the doors to be able to open and not fall through the floor do you know a fix @ All_Sor

Would be massively appreciated!
