I'll admit its not the best...kind of blurry...I'll attempt to fix that and make it a bit more realistic...

That looks a lot like a fern spore in your first image!?

Sure;) lol I was going for shader only. So I win! HA! lol. Hey, send me that scene file so I can check out your lighting! Please. (email below) Thats a nice effect. I think if I used anything grooves, I could get a better effect with my shader, as well as decrease the noise value size. I'll give it a try tonight. bnh2@comcast.net

All I used for lighting is an anything glows torus located just outside the frame. The essential feature of an scanning electron micrograph (which is what I think you're trying to duplicate) is that the brightness of any given point is a function of its angle to the viewer). In other words surfaces that are oblique to your eye are bright and surfaces that are normal to your eye are dark. There are other effects too but that's the main one. Please let me know how to do it with a shader! Ed

I think I could do this with a formula shader. I'll experiment. I'm sure I can do it. When I do it will be in my texture pack. Brian

This image by Digital Blasphemy simulates a scanning electron micrograph so exactly that I (a SE microscopist for 15 years) could not tell the difference. He does it with glow I guess in lightwave. A very nice image.ED

Yeah I have a few ideas, the main thing I am trying to do is get the lighting to come out right, the shades of gray or color to look the way its suppose to. Brian

Some links: http://www.pbrc.hawaii.edu/bemf/microangela/ http://www.mos.org/sln/sem/sem.html http://swehsc.pharmacy.arizona.edu/exppath/micro/edu/imagesites.html Doing a little research going to do this one well and right. Thought others might be interested in the links.

http://www.umic.sunysb.edu/sempoll.htm This is the type I'm shooting for. And make it so a quick adjustment of the color can create the various looks.
