Maya for 3D Printing - Rapid Prototyping

In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

hy. I have big question. What bump map should I use to get detailed pores that oranges or lemon have ? I need this on a lemon actually. I made the lemon, now I only need the pores. I have used a bump map but I get really poor results. I attached the bump map so you can tell me what is wrong. please anyone help me get those detailed pores I need a close up of the lemon. Thank you a lot.

The reason your not getting the desired results with this bump map, is the simplicity of it. At the moment your bump map will simply put small holes on the surface of your lemon, whereas an actual lemon has a rougher surface. With a much more lumpy surface.

Try this: (make any edits you need to it to gain the desired results.)

you gave me an excellent bump map thank you !!!! but please tell me how to fix this problem: I want the bump map to be the same size everywhere. I attached the screen shots. at the tip, where all the isoparms meet, there are many points but very little and in the middle few and big. Please help me. Also how to make the bump map repeat more times on the lemon. Thank you a lot !!

When this texture is applied to the bump mapping parameter of a shader node, such as Blinn. The texture doesn't get pinched as yours has. So I think it's because you have too many isoparms all coming together at that one point.
Try building the lemom with allot less isoparms.

To make your texture repeat, do this to your Texture placement node:

I'd say just go model it in ploygons, then UV map it and then smooth it out any way u like user added image
