Fully customizable Portal System

Current Limitations:

• Lumen not supported.
• Recursive rendering is performance killer right now. I want to do a performance update soon.

Features:

• 1:1 Rendering
• Smooth player and objects teleport with velocity
• Smooth 3rd person camera transitions
• Contains Laser System, Lasers can interact with portals
• Cloned character and objects on linked portal
• Projectile pass through the portal
• Recursion support (update for performance coming soon)

How-To

1. You must enable “Support global clip plane for Planar reflections”

   Edit -> Project Settings -> Rendering

   

2. Set near clip plane to 0.1

   

3. You must create object and trace channels and Collision presets like this: Edit -> Project Settings -> Collision

   

   

   

4. These settings are saved in DefaultEngine.ini under CollisionProfile section.

   You need to find out to which GameTraceChannel is set to your custom traces. In my case it is set to like this.

   [/Script/Engine.CollisionProfile]
   +DefaultChannelResponses=(Channel=ECC_GameTraceChannel1,DefaultResponse=ECR_Block,bTraceType=True,bStaticObject=False,Name="LaserTrace")
   +DefaultChannelResponses=(Channel=ECC_GameTraceChannel2,DefaultResponse=ECR_Ignore,bTraceType=True,bStaticObject=False,Name="PortalTrace")
   +DefaultChannelResponses=(Channel=ECC_GameTraceChannel3,DefaultResponse=ECR_Block,bTraceType=False,bStaticObject=False,Name="PortalWall")
   +DefaultChannelResponses=(Channel=ECC_GameTraceChannel4,DefaultResponse=ECR_Block,bTraceType=False,bStaticObject=False,Name="PortalActor")
   +DefaultChannelResponses=(Channel=ECC_GameTraceChannel5,DefaultResponse=ECR_Block,bTraceType=False,bStaticObject=False,Name="Projectile")    
   

5. You can modify all assets via DA_Widget_Simple and DA_Portal. (These files are derived from the UDataAsset class.)

   

   

6. And that’s it… You can set the default pawn class to BP_PortalCharacter.
