Ability to make areas inkable, uninkable and grates about splatoonsweps

[ZenkakuHiragana]

Thank you for your suggestion!

I agree with your idea as I think automatic surface generation can't be perfect and thus it will be eventually needed.
I'm thinking of a handy tool using the Tool Gun to edit the generated surfaces like Navmesh Editor.

Currently the SWEPs supports two material properties:

• Grates (materials with $surfaceprop set to "metalgrate")
  Materials which bullets can go through also allow squids to pass through.
• No portal area (materials with %noportal set to 1)
  You can test this in any Portal 1 maps which have metal walls.
  Currently, the no portal flag indicates non-inkable surface.

I should also note that almost all ported Splatoon maps don't work as expected because they all are really different from other maps in terms of internal structures.
For example, you will see your bullets don't go though the grates in Hammerhead Bridge.
I guess this is because the grates are not recognized as grates by the engine, so it needs a special workaround to fix.
It seems ridiculous that Splatoon weapons don't work in Splatoon maps, so I'd like to do some workarounds for them.

Some stock grates and iron surfaces already have their proper functionality, but most don't.

Do you have any known map with incompatible materials aside of Splatoon maps? I feel rather "most materials will work as expected, but some don't," except for ported Splatoon maps.
