Okay, I think the problem is addressed here: new-feature-request-solid-ignore-select-solid_t79689
Which leaves me trying to create a new stairs function using jump-throughs. Here's an idea I had which, in theory could work if I could "fall through" to loop faster than the platform engine registers: https://www.dropbox.com/s/qtgg5itcficxi ... .capx?dl=0
Setting "fall through" for the player on every tick isn't good enough though, I need something that is faster than the platform engine can register the jump-through platform. If you walk slowly through the stairs, you can see the player just slightly goes up then keeps walking, if you run at full speed, the player skips over the "fall through" action. Is there a way this technique could be harnessed to create proper a staircase?
