perforated steel plate

how can create a perforated stell plate( with round perforations for example)? or even better, where I can find a object like this ?

Such an object would require too many polygons to be practical since each tiny hole would be defined by at least eight polygons...... you'll use a fill pattern to define the surface in anything but a photo rendering, and in a photo rendering you'll use a texture map with a mask for transparent holes.

Attached is an example of a screen pattern I use.

Depending on exactly what yu need, you can draw the pattern in photoshop or use a photo from a metal catalog.

This example is from a metal catalog for expanded metal.

so it is an exercise in my book - use the pefed metal file to create this material - watch the sizing - note that for ArchiCAD 9, it uses the mask channel that ArchiCAD 8 does if you tell it to match.

an example in use - LightWorks rendering - note flaw in LightWorks - can only render the front faces of the block - that perfed metal is wrapped all around the slab, but the rendering engine treats it like a folded sheet - look thru the holes to see what I mean.

BTW: see how the metal color is controlled through reflectivity rather than color - the texturemap is white. This way, other colrs can affect the surface more easily making the image more lively.

Still feel pretty dumb. Pass me my cane, would you please?

In view of the fact that if this darned book is to ever get done, I must enter a manic phase, you all will be hearing from me a lot in the next weeks..... blah blah.

One way of getting there ...

Coming back to perforations, that is one thing Art•Lantis does better than LW.

I took that as a challenge.

Of course, we could be talking sandblasted, in that case you'd put roughness to about .8

or hammered, in which case you add some denting.

Got that second sun in there - cold directional light with no shadow....

was this steel or aluminum -- or aluminium..... ?? or painted??

That's that, mattress man.
