I have made a new element PYEX I copied the powder.h code for glass and compiled just to see whether it works, but it seems to instantly disintegrate when I place it somewhere. Here's the code: #define PT_PYEX 165 at the end of the define list
This is very popular problem, but I now solution: #define PT_..... or /*elementname*/ {IPL, NT, IPH, NT, ITL, NT, ITH, NT}, lines arent in correct order. or #define PT_..... have vrong numeral value
