Hi there ,
i found where is the solution of my problem 
i just have to copy/paste all custom materials taht i have in R3 into R4 materials folder
all custom materials from R3 - \ZStartup\Materials
must be pasted in the R4 - \ZStartup\Materials
I thought that when i save project file all materials and settings are saved in the project file too , but i was wrong , the project files save only custom settings form the default materials that comes with zbrush but if i had download some other material the project files can’t save this settings
