Hi I was tryng to search on the forum but didn't find any usefull answer,I am tryng to use the special material name ZBIAS_01 as state on the SDK on some 3d object like several layer of needle in the vc. but i am not luky as they mix and don't shows correctly.I just apply the material ZBIAS_01_needle01 to the last polygon then ZBIAS_02_needle02 to the top one, but it dosen't work. What is missing? I am also having another problem, I use some circle polygon for GDI screen with subdivision of 24 segment, but when translate with makemdl, those circle loose accuracy and become less segment.Is there a way to to tell the accuracy on convert poly with makemdl.Thank youFabrizio

I find that the correct command is z-bias and if I put an needle in front of a $ panel there is no way of use this facility. Is that correct? or there is another solution.Thank you
