Customizing, reskinning, and 2 new test elements
So, if you didn't know, I'm making a custom themed map. It's going very well, and I love customizing everything. The actual map would take place within Aperture Science Northern district.
(Sorry Fourth Reaper, I just loved Penrose. I can change it if you want!)
I was wondering 3 things:
1. If I was to add custom music that I made, how would I do that? Would I have to use pakrat? A tutorial would be nice.
2. Can you please refer me to a tutorial on how to reskin a cube?
3. I had an idea for a new test element: the light emancipation field. It'd stop lasers, light bridges, and excursion funnels but not cubes, people, or portals. I think I'd be interesting, but I have no idea how to make it.
Thanks for any and all help.
Oh, and the other test element is electric grating. It's self explanatory.
1) Put it in the portal2/sounds directory, then use an ambient_generic. If you want to release on the workshop you need to pak it, but that's the last step.
2) http://forums.thinking.withportals.com/mapping-help/reskinning-how-to-t4041.html
3) Try a func_brush with the toolsblockbullets texture, but that might block portal shots too.
4) Grating texture with a trigger_hurt around it.
Thank, that helps.
(I already knew how to create the electric grating, but thanks anyway.)
But with the light fizzler, it works only when the toolsblockbullets brush is set to solid, which then I can shoot portals on it, so... (And lasers always pass through it.)
In that case I don't know. Try putting a trigger_portal_cleanser on top of it with all its flags off, then it'll just block portals like a fizzler.
func_noportal_volume is what you want. Also, I've never found a material that stops lasers, so it could be tough for that.
Hmmm... I don't this brush entity stops anything, it will just avoid that any portal is open if a white (or any texture with the parameter "%noportal" 1 inside its .VMT file) surface is inside that volume

Strange, I got it to work on a floor texture as well.
I meant that you can't block portals with it like a fizzler. It only makes the wall or floor that they are spread on non portalable without vmt edits. It works on floors too.
