@powder_master(View Post) For more advanced usage,you can click on a blob (or particle) of CONV and change the value "ctype" to the element you want for it to convert. Then it converts the element you specified. Example:
you change the ctype of conv and it convert's everything that touches it to that particle type you get it now. you can use the console for ctype or click on it with a particle (note this is just the pixel's you click) and with the property tool you can set ctype now.
