Hi everybody
I've just found a crash result for the 2.1.5 release :
UVW map on point clouds railclone object... Vicious thing that don't prevent everything, i can merge everything, that's why i've found the problem, everything crash wit railclone object, and each which crash are (accidentaly) with a UVW map modifier on them, but only those with a point clouds preview mode crash...
Hope it help...
