I am new to mapping, so I dont know if this is definitely a bug or not, but I have created a test map where I test new things that I dont quite understand. I have created an angled surface with an info_placement_helper on it.

When I fire a portal at this place, it goes there not a problem. But every time I walk through the portal placed on that surface and the other placed anywhere but ground level, I get shot through the portal. I have uploaded a video to youtube, so you can see what I mean. All other portal placements work fine.

In the console, type sv_player_funnel_into_portals 0

Unfortunately this has no effect on what is happening.

could you upload the vmf file? that way we can look into your map and maybe see what's wrong

The file as requested is below. I also included the bsp as it is compiled on my pc.

from what I've seen your placement helper is a few pixels in front of your surface, try to make it so that the blue and green lines are IN your surface and red is sticking out, that might solve your problem

Try setting the radius of the placement helper to 20

Unfortunately neither solution works. But what I did notice is that when I place the portal any where but on the centre of the angled surface, using the heler to place it, it does not fling you through the portal.

Anyone got any theories on this at all ? :-\

Theory: Hammer was being emo.
Solution: cut out the original panel, forget it ever existed and place the copy!

95% chance your problem is "solved"!
(hammer can be pretty random)
