The way you have showed me I have to make special Xy new variables<BR /> and I will have to check it by clicking it in properietes instead of checking it visualy by material<BR /> with one line of code Tue, 19 Mar 2019 14:38:53 GMT https://community.graphisoft.com/t5/Collaboration-with-other/Weight-from-material/m-p/291249#M38028 Anonymous 2019-03-19T14:38:53Z https://community.graphisoft.com/t5/Collaboration-with-other/Weight-from-material/m-p/291250#M38029 Yes, I agree.
