As shown in the attached renders. i painted the trees with the brush as global echosystem, and they behaved normal. But according to my needs i wanted to reduce the size of the trees so i used the brush from global echo-system's options to rescale them and reduced the size and wen i rendered the same scene some of the trees started behaving quite weird. u may have a look at the attached image. In this particular scsne, the tree type that is creating problem is the old eucalyptus tree from the default trees given by the vue itself. but its not fixed that only this tree creats problem. even summer cherry tree, plum or any other (randomly) creates problems.
in this particular scene am using three types of trees and the number of instances are around 500.
so please help me solve this problem or even tell me y this occurs. initially i was thinking that this problem arises in the files having large number of tree instances, but this fils contains only 500 trees and still have problems.
waiting for ur reply.
Thankyou in advance.
