I'm having trouble with some things.

1. I can't seem to add collision cubes/planes. I click the icon in the toolbar and then in the renderwindow, nothing happens. Do I have to do something else or is something buggy with my CK? And yes, I've toggled markers on.

2. Is there any way I can add an area in a waterfall where I'm not knockedback. Currently there's a huge waterfall overlaping an area I want to have access to, and there's a lot of knockback in that specific area. I could rotate/move it a bit, but I'd rather not as would have to change some things around it.

3. Is there any way to get a lightable fire by torch? I've tested this method where a trapoilpool activates an inactive fire, but it doesn't work for torches as they don't light oil on fire.

Kindly answer and I'll be.. um, greatful
