Hello.
Automatic item pickup can be set for virtually anything. You can set this in the install.xml file inside the mod.
Look for a script "Auto-Pickup Quest Items" or "Auto-Pickup Consumables" in this file.
<script type="optional">
<title>Auto-Pickup Consumables</title>
<description>Your character will automatically pickup consumables when you are close enough. This does not apply to drop from events.</description>
<table id="items">
<entity id="2,3,4......250,251">
<attribute id="bitmask03" bit="autoPickup">true</attribute>
<attribute id="autoPickupDistance">4</attribute>
</entity>
</table>
</script>There is a long line of numbers in the "entity id" line, and each of these numbers represents one item that will be picked up automatically.
Download the Reanimator program from Hellgateaus, and open the "items" table in it.
In the list of items, select the item you want and add its number (in the "index" column) to the other numbers in the line "entity id".
Essence, for example, has the following numbers: 1940, 1941, 1942, 1943
Unfortunately, no one has yet managed the automatic item dismantler for singleplayer.
