Are any other windows users having the same yafray problem with the latest version for 2.34? i keep getting this dialog box that pops up saying that it cant find cygwin1.dll and to try reinstalling the application. Well i have tried installing cygwin AND reinstalling Yafray but i STILL get this problem. Is this a Yafray or blender bug?
this thread on the yafray forum should help you out:
that links not working, anyone know how to fix this problem?
delete your installation of yafray using “add/remove programs” in the control panel. this will get rid of registry settings that cause blender to barf on yafray rendering.
then re-install the 0.0.7 version of yafray.
