Game Kit: Portal (C++)

Screenshots

Fully customizable Portal System

Current limitations:

• Lumen is not supported
• Recursive rendering is currently expensive; a performance update is planned

Features:

• 1:1 rendering
• Smooth player and object teleportation with velocity
• Smooth third-person camera transitions
• Laser System integration
• Cloned characters and objects on linked portals
• Projectile traversal
• Recursion support

How-To

1. Enable Support global clip plane for Planar Reflections

2. Set near clip plane to 0.1

3. Create object and trace channels and collision presets

4. Add the channels to DefaultEngine.ini

[/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. Modify assets through DA_Widget_Simple and DA_Portal

These files are derived from the UDataAsset class.

6. Set the default pawn class to BP_PortalCharacter
