so i've been attempting to make a custom particle for my custom story but whenever i hit the add material button the particle editor crashes! this is a big part of my story and if i can't get this working that would be pretty bad... please help!
Not a solution, but you can get around it by duplicating and editing a .ps file in a text editor to change the material and then use the editor to do the rest.
You have to be carefull with the res you use in the material. Make sure you use a material the same size as the others used for particles.(If you are using a custom mat).
