A Visportal observation

[grayman]

I've been mapping since February, and never really gave a thought to the visportal red and green lines that appeared in the sky (using a skyportal) when I was using r_showPortals. WTF? VPs in the sky? So what, move on.

 

Until the other night, when I realized the lines in the sky are from the skybox's camera view.

 

So, if you're using a skybox, and debugging your portalization, you have an additional tool available, a camera that can give you a bigger picture of what VPs are on and off.

 

Maybe the experts here already knew that, but it was one of those Aha! moments for me.

LOL I didnt know that either...

I 've seen that too but thought it's a bug not a feature.

 

Still not sure about it. I figured when I look in the opposite direction of my skyportal camara (propably when the camera sees me through a visportal although it is in a void-separated part of the map) the sky occasionally vanishes and just turns grey.

 

Didn't want to investigate further though.

I don't think that should be. I think if your skybox is far separate then it won't see portal lines from the map. I don't ever remember seeing any visportal lines from the skybox, but it's been a while since I checked

Yep, it's true. Debug visportal lines have depth priority in front of the world. I usually put my 3D skybox well above the world to avoid this sort of confusion.
