Hi Bruno, I expected that materials in Ip2_... would be already ordered, but they are not. I didn't have time to study why. Most likely there is some better way to do it, I just gave a working solution for Behzad's urgent question..
I checked goReverse some days ago and if I remember correctly, it is used only in Ig2 functors. Behzad's situation (combining two different materials) is not very common in Yade. I used something for combining FrictMat and CpmMat into FrictPhys, but CpmMat is considered there as its base, FrictMat, so as a result two FrictMats are combined. Maybe it would be good to investigate the problem more in detail and at least for future occurrences propose more clean way. cheers Jan 2015-02-21 14:15 GMT+01:00 Bruno Chareyre <bruno.chare...@3sr-grenoble.fr>: > Hi Jan, > Do you think that goReverse cannot solve the problem?
