Seamless Portals

[Fatorice]

@Schytheron

I am facing the exact same issues as you. Tried to first write it in C++. Everything went fine until I got to the “GeneratePortalTexture()” function in the portal manager class and it all went downhill from there because I could not figure out the structure or what his custom “UExedreScriptedTexture” class looked like because never showed it. I tried to replicate it best I could by making estimated guesses. It compiled, but the editor crashed as soon as I hit “Play”. Great. Eventually I managed to get it to actually run after I changed some things in my custom implementation of the “ScriptedTexture” class.

It played, but now everything was broken. Render texture is blocked by an overlaying default texture, render texture refuses to clear itself and just overwrites itself every tick causing a blurry mess, teleporting is very inconsistent, my mesh deforms incorrectly etc. (video of the issues: https://www.youtube.com/watch?v=0gQSsQ20LHc).

At that point I just said “F*ck it!” and attempted to rewrite the entire thing from scratch using BP (but using a different portal mesh this time). I didn’t get far. Got stuck at the teleport section because my “TeleportActor” function in Blueprints applied the wrong rotation to my player every time I teleported (as detailed in my previous reply). Now I don’t know what to do… this is so frustrating.

It seems, that I’ve found the line, where it comes to crash:

PortalTexture = NewObject<UTextureRenderTarget2D>(this, UTextureRenderTarget2D::StaticClass(), *FString("PortalRenderTarget"));

Someone know a fix for it? Or how did you solved the crash problem?
