Thank you for friendly and very prompt answering. I think I understand the problem.Let me tell you. I download the update.It should fix a lot of problems, even the bum material problem-but some promises like this, look like a little lie. But ok this is easy to manage by handmade edit of bumps. I set the transparency to 100%- and it works fine. Now the hair looks great again. I try it before and it doent work so I ask myself why. But there is I think it is a programm bug-a bug made this problem.If I choose any other controller or setting in the transedit-I see it in the preview and take it back-go out with only set trans = 100% --Then the strange effect is there. illogical but a fact. But to touch nothing else than take tran. to 100,let it work fine-so it is ok. Anyway I will try to upload a picture with the problem The other and quicker idea to set it into poser to 100/100 trans. looks like a quicker solution. Thank you carol for this good idea.
