There is no X-Ray module for Vape v3/Vape Lite.
There is however a different version of it, which is more stable/allows you to search for not just blocks;it's called "Search"
If you cannot find this, it's not in the "Render" section like you would probably expect. Check for it in "GUI" on Vape v3. For Vape Lite, it's quite obvious where it's located.
To search for ores, just insert the block name you want to find. (i.e. diamond ores, "diamond_ore")
Use chams to see playersI think what OP was trying to get at was to add in an x-ray module to Vape, as this is the suggestions forum. While I understand Search exists, I feel like a wall-hack module with opacity configuration and a whitelist of blocks to view would be very useful.
