A Hollow cone. Wish since the unity version begins.
There are other threads with missing shapes. Problem is that you have to write a thread in English and German, but sometimes this is not done.
Btw you can resize every material into a pane and also use it with copy.
Yeah unfortunately I don't know German and I don't trust translation programs, etc. to always get it right so I can only do the thread in English. If there's someone that's fluent in both languages willing to translate any German posts for me that would be amazeballs. Just trying to save Red a whole lot of time by compiling a list in one place instead of him having to sort through tons of posts himself.
Ohhh that's a good one with the Hollow cone, yeah definitely one to add. I've just been using the hollow cylinder and a regular cone combined for that shape.
As far as the can resize every material into a pane. Yes you can, but the dedicated panes for fabrics and papers would have the semi transparent material quality set to them (much like the milk glass, etc.) and that's something you can't achieve with the resize method.
