_manifest

_manifest is important file. Its needed if you want ymaps to proper spawn objects.
Theres only one manifest for RPF.

<MapDataGroups>

Here you definies all static collisions for each #map. Thanks to that when loading/unloading #map by script, static collisions will be loaded/unloaded at same time as #map.
For example:

<MapDataGroups>
<Item>
      <Name>here ymap name</Name>
      <Bounds>
       <Item>here static collision name</Item>
         <Item>here second static collision name</Item>
     </Bounds>
   <Flags/>
       <WeatherTypes/>
       <HoursOnOff value="0"/>
       </Item>
</MapDataGroups>

<HDTxdBindingArray>

Its used for textures parenting.

To set texture parenting (switch between high resolution and low res)
1. For #dr with embedded textures
In manifest under <HDTxdBindingArray>
set:

<Item>
   <assetType>AT_DRB</assetType>
   <targetAsset>name_of_ydr_with_embedded_textures_here</targetAsset>
   <HDTxd>name_of_ytd_with_high_res_textures+hidr</HDTxd>
</Item>

2. For fragments (YFT)
In manifest under <HDTxdBindingArray>
set:
<Item>
<assetType>AT_FRG</assetType>
<targetAsset>name_of_yft_here</targetAsset>
<HDTxd>name_of_yft_here+hifr</HDTxd>
</Item>

3. For objects with external textures
In manifest under <HDTxdBindingArray>
set:

<Item>
<assetType>AT_TXD</assetType>
<targetAsset>name_of_ytd_with_low_res_here</targetAsset>
<HDTxd>name_of_ytd_with_high_res_textures+hi</HDTxd>
</Item>

In #typ hdTextureDist value set distance for display of high res textures

<imapDependencies>

<Item>
   <imapName>interior_ymap_placement_name_here</imapName>
   <itypName>interior_ytyp_name_here</itypName>
   <packFileName/>
</Item>

<imapDependencies_2>

<Item>

and/or

   <manifestFlags>INTERIOR_DATA</manifestFlags>
   <itypDepArray>
       <Item>ytyp_name_here</Item> <- define here all #typs for objects used in interior
   </itypDepArray>
</Item>

<Interiors>

<Item>
   <Name>interior_collision_name_here</Name>
   <Bounds>
       <Item>interior_collision_name_here</Item>
       <Item>hi@interior_collision_name_here</Item> <-if you have hi@ or ma@ collision put name of it too
   </Bounds>
