I have a problem with random ‘blank’ lines appearing around objects after rendering. The weird thing is, it all looks fine while its still rendering but once its finished the part of the image its been rendering it seems to go over it again adding those blanks.
this is mainly the case with these trees here i got from this page: http://yorik.uncreated.net/greenhouse.html, but it also happens with a few other materials.
(the trees work fine in their original blender files)
Heres a render to show what i mean:
how can i fix these blanks??
