holes in a surface

[clankill3r]

I need something like this:


It doesn't have to have any thickness (so if it looks like a paper with holes it's fine).

How can i do something like that?
I asume it's possible with materials, so that's why i post it here. If it is possible another way then it's also fine.
O yeah, it would be nice if it allows light to go threw.

Use a dots texture (black with white dots) and connect it in the Trasparency node of the shader (Phong, lambert, Mia, etc...).

Use a dots texture (black with white dots) and connect it in the Trasparency node of the shader (Phong, lambert, Mia, etc...).

Or the cut out slot of a MIA material.

Or, when the dimension are known, create the pattern in Illustrator and export/import the file.
Extrude, bevel etc. and be happy.

thanks, i will try later.

The mia_material has no cut out slot, is it named different maybe?
Also to get the depth, is extrude, bevel etc. the only way?

I got it working with a texture now but the shadow of the object itself is like there is no transparency on the object at all.
I can understand why this is the default, but how can i change this?

You can use displacement for the thickness, though the mesh will need to be subdivided enough:



use one polka dot image for the cutout, and then create a second for the displacement in photoshop by either blurring a duplicate layer or use the handy layer blending outer glow options to make a black glow with different edge bevelling styles. Hat tip to Jules Stevenson for that one.

If you use larger dots and a repeatable pattern you won't get the pixel noise I've got in the image above.

I usually model 1-4 holes depending on pattern, duplicate polys and snap & move with help of temp pivot, weld boundary vertices, then again with bigger chunk duplicate, snap, move, weld, and so on...and with final shape apply thickness
