EoH - Modular Tunnel Pack

Summary

This pack contains a collection of rooms, pathways, doorways, entrances, and other items built to modularly create tunnel systems. 

Originally designed for use on EoH Vietnam Servers

Description

HOW TO USE:

>Snapping
- Each object contains "memory points" which enable the move and rotate tools to snap the prefabs to others
- Take two prefabs, select the move tool, and under the tool options window turn on the options of "What to drag" and "Where to drop" under point to point snapping to "Bone"
- Hold B while selected to one of the prefabs, click one of the white cubes that appear, drag that cube over to the cube on the other object

>Creation
- It is reccomended to start from an entrance, place one in, use the Hole feature of the Terrain Tool to create an opening for the entrance, and adjust prefab positioning to fit the created hole.
- IMPORTANT: You will need to place some sort of prefab in-between the terrain and the tunnels to block incoming light, the terrain seemingly does not block light from my testing, I used the "GridPlane_100x100" prefab for my testing, ensure you disable the rigidbody component on it to have no issues with colliders.
- Branch off from this entrance by snapping other prefabs to this entrance's memory point
- When you wish to add a room, cap off your pathway with the appropriate doorway, the memory point further back on the doorway should be snapped to the end of the pathway, and the doorframe you wish to use in the room should be snapped to the front memory point of the doorway
- Other doorframes in the room should either be utilized via more pathways (and accompanying doorways), or capped off with either the "Blocked_Doorway" or "S_Blocked_Path" prefab. 
- IMPORTANT: The ending of all pathways will not line up with doorframes, this can be remedied via using one of the included "Masks", which are an outline of the standing/crouching/prone shapes I've made, just snap it into place with the memory points. These can also be used to cover any gaps that appear in putting together the tunnels.
- Exits will invevitably end up misaligned from the grid that you use to create your entrance, you will need to place other vanilla prefabs and/or shape your terrain to accomodate them.

>Other
- All bugs or issues can be reported to =45= in the EoH discord via ticket or DM
- All objects within the pack intended for use inside tunnels are fitted with probes, intentionally set to be quite dark. However I did not figure out how to make prefabs placed in the tunnels to decorate them be similarly darkened, if you know how or if I can fix this on my end please contact =45= in the EOH discord via a ticket or DM.
- You are free to do anything allowed under the APL-SA license with this pack, retexture, override, utilize, etc. however you wish for your own projects. All I ask is credit as I made everything in this pack myself except the textures.
- Updates are planned, but are not a priority to me at this time. I will be trying to implement some very shallow LOD work at some point as 1.0.0 does not contain any. Eventually planned is some method of traps to be implemented as these are orignally designed as the infamous "Vietnam Rat Tunnels" for EoH Vietnam. I will attempt to make updates to the pack not cause issues with existing usages.
- I've made a video tutorial showcasing the creation of a small tunnel system for those who would benefit from visually watching the process, it is quite long but can be watched at 1.5-2x speed fine. https://youtu.be/y1rZXEIEKvs?si=gPvO_LBWGeIsyJ77
