Making holes in items

Posts: 536
I want to make holes in things - clothes, furniture, accessories, etc. How do I do it? I can in some cases create a base map with the holes in and apply it, but this is not always successful. Sometimes the image becomes translucent but there is no hole as such - especially with items having thickness or depth to them. Is it do-able or a non-starter, pelase

If the item becomes translucent is that in preview or render? The preview has problems with overlapping transparencies (working out which one was on top would slow processing down so we tend to get the back layer showing through, even in areas where the map should completely mask it).
AHHHH! It may be the preview pane. I'll have another look.
Thanks.
Nope. That hasn't worked Richard. I am trying to show somethng in an enclosed space with openings in the top, so that (as it were) there is a box with just one side missing and holes in the top through which the only light is shining.
Well, in Iray you could use an Iray Section Plane to cut the top off - but how is the transparency map not working?
From the Tools menu, use node selection to pick out the item, then in the same menu, use the geometry editor to pick out the areas (polygons) that you want to disappear. (Ctrl-left click to select more than one) Then right-click, choose Geometry Visibility, and left-click on Hide Selected Polygons. Finally, in the same menu as Geometry Visibility, go to Geometry Editing and left-click on Delete Hidden Polygons.
I've done this with a lawn to make a hole for an in-ground pool.
I am not sure about either of these. I will try to recreate the issue and post an image. It is not an urgent idea, but one I would like to solve. In essence, the item appears to have an upper and lower (inner/outer, front/back) surface with no obvious means to align any holes. If I 'drill' through one surface I can't fathom out how to match it on the inner surface. If I make only one of the surfaces work the effect is wrong.

I don't think there are appropriate polygons, and I don't feel competent to create them, but thanks anyway.

The absolutely easiest way I've found is to bypass Daz3d and bring up Bryce (also a Daz3D product, and a very good and versatile one. If you don't already have it, you should get it - it's cheap, and will do a ton of stuff that Hexagon will do, only much, much easier and tremendously less geeky.)
1. Create the form you want by selecting one of the basic object shapes at the top of the window and manipulating it into the shape you want.
2. Then, on the list that shows up right beside the object you ceated, click the "A".
3. A menu will come up that lets you determine the qualities of the object. Make it "positive".
4. Then, create another form in the shape of the hole that you want.
5. Click the "A" beside it and make it "negative".
6. Move the hole shape to intersect the main form however and wherever you want the hole in the main form to be.
7. Select the two and group the two together (Shift & click on each)
8. Click on the "G" that's on the list right beside the group. It combines them into one shape and you now have your form with a hole in it. .
9. Once you get the object the way you want it, >>export<< it as an .obj and then >>import<< it into Daz.
NOTE: If you want the hole to go all the way through the object, you need to make the hole form long enough to do that. If you want it to just go to a certain depth, (like making a cylindar into a cup), only make it that long. The hole form won't just make the hole, but will also make the walls of the hole, automatically. In fact, if you want to give an object odd-shaped dints or odd surfaces, this way of doing it is WAY easier than going into Hexagon, Blender, or any other object-design program and messing with points, edges and faces to get the odd shapes you want. Just make the shape of the hole and barely press it into the main form, make the main form positive and the hole negaive, and voila! you've got a dint of that shape in the surface of the main object.
I hope this helps.
Hey, I want the same as the thread creator, so I push it up :)
I have here 2 objects, but Modell A have not a hole just "drawed" on it. the holes was simply black, I edited the material in png and removed the holes, but now I realize that doesnt help if the "3d object" doesnt have holes there...
I did try the geometry editor, but I can`t select a dot/circle, because the frame isnt build in dots...
The geometry editor works fine, but sadly it hides all and not just a circle...
is there a way to change the geometry and simply create a hole?
Can't you just paint it black in the Cut-Out Oppacity map?
The original was black, I did remove the black, because it did just showed "fake" holes, but I didnt wanted fake holes, i want that you can look through the item.
If you in the cut-out oppacity have a white image with a black spot, then the white area will be rendered, but the black spot will be transparent and show what is behind.
sorry... I can't follow you... atm. the object have no holes, it was first on all images just a black dot to "fake" there is a hole, I did simply delete them so its a png image with holes, but now its in the editor+render just a white point.
In the attached image I took a DS plane and a DS cube.
For the plane I colored it red and added a white image with a black cirkle in the Cut-Out oppacity.
What is... DS? :D looks like the basic objcts, are they called DS?
@MrDarck DS is a common term for Daz Studio. Felis is refering to the primitive objects provided in Das Studio using the "Create New Primitives" tool or menu.
