Hi Adam,
Thanks for your help on this, I originally imported an obj file which might of been where the issue came from. I have been using the model I adapted from this obj file for a while with no issues, recently I have come across Vray so I am trying to render this project in Vray which seems to be where this happens.
Scene file is here: 9025_010.c4d.zip
I tried removing the normal tags but the issue is still there.
I haven’t tidied up all the objects as i am still working on which parts animate with which, this could be where i have moved something ????
thanks again for your help
