Man-Shaped Holes

Hi, everyone. Just curious: apart from actually using 3D software like Carrara, Maya, 3D Studio Max etc, is there any way to create holes with a human outline (on walls, floors or other surfaces) in DAZ Studio, or are there any items for sale which would enable you to create such cavities? The SimTenero Shape Reprojector looks promising, but does it allow you to create holes in the shape of various things you select, such as a Genesis figure?

I attach a couple images here to illustrate more exactly what I mean by 'man-shaped holes'. ;)

    The Reprojector needs high-enough mesh resolution to work - it can't add vertices - and makes dents rather than holes, though with a bit of care about angles or the use of a Section Plane or some shader trickery you could probably hide the dented in/out mesh.

    Daz doesn't really let you 'cut' the mesh from what I've seen.

    But you can use geometry editor to select a 'man' shape on the mesh and set their opacity to 0. You could also use photoshop to create an alpha map for the texture of the object you want to put the hole in.

    Unfortunately, both types of 'opacity' holes are more 2-dimensional looking than the examples you posted.

    If you find an easy way to achive what you're after, I'd be interested! I watched C4D and houdini tutorials on youtube the other day where they had 'knife' tool to actually cut a mesh. That looked super cool. But I prefer to stay inside Daz Studio so am always looking for ways to do similar stuff entirely within Daz.

    Just read richard's post. The reprojector/section plane idea is very interesting! I'll have to try it sometime as it could give a more 3D look.

    As for 'cant add verticies'...I thought daz could do that via the tool which adds SubD...but maybe I'm wrong.

    Thanks for the feedback, fellas!

    Pity. Was hoping to do a macabre render featuring such holes -- maybe with creepy things reaching out of them. :P Looks like you'll probably need 3D software like 3D Studio Max or Carrara after all... :(

    Well, hopefully the vendors here at DAZ will take note and try their hands on creating something like that for us all. Hopefully with poseable holes. I'd buy it! ;)

    Maybe you could 'elongate' the dented-in mesh along the right axis for it to appear more like a hole? :)

    Yes, I was going to suggest that as another option.

    Another option is that you could place the figure in the dent (assuming it's reasonably deep) and give it a smoke shader:

    refraction index 1, weight 1, set thin shell: off, give it Transmitted color of dark blue or something, set transmitted distance to, oh, 5

    Put that on a figure, and they become a smoke creature. Place it in the dent, and it essentially occludes the bottom, making it look much deeper.

    Unless you need more than just a black hole on the other side of the opening, you could try putting a plane across the back side of the dent created by the shape reprokector morph. Make the plane black with no reflectivity... If you need the back side of your opening to be jagged, you couuld use an opacity map along with the morph... just brainstorming here...

    I hope you get it figured out and come back and let us all know what worked for you.

    1.) Select the object in the scene that you want to behave like a "shadow catcher"; in Iray these are called "matte objects" and they do more than just "catch shadows"
    2.) In Content Library pane, navigate to and load DAZ Studio Formats > My DAZ 3D Library > Scripts > Utilities > Create Advanced Iray Node Properties; this script is provided by the Default Lights and Shaders package
    3.) In the Parameters pane, navigate to and activate the Display > Rendering > Iray > Enable Iray Matte property

    maybe something using that technique

    Couldn't one just use displacement?

    I've been kind of wanting a hole for characters to climb out of like a crater or rocky opening in the earth. The best I came up with was using a cave and flipping it so the cave mouth was in line with the ground. Maybe something similar could be done to make your dimensional holes.

    Displacement could be a viable option if you're rendering in 3Delight. But from what I've read and seen first hand, it wouldn't be viable in Iray.

    tough call

    your enemy here is the texture, without going in with Hexagon or something,

    your texture is going to be a mess.

    Photo Shop might be able to do it.

    good luck

    Would be great if someone here who bought the SimTenero Shape Reprojector (which frankly is a bit pricey :( ) could try doing a man-shaped hole and show the render here. If I were sufficiently impressed I'd seriously grab the Reprojector. (When it's on sale or when I'm sufficiently loaded, of course -- or both. :P )

    Hi,

     

    I simply played around with Bump.
    First I rendered a character without any light as PNG. The result got a black & white rework (unsharpen, gray-scale, ...) in PhotoShop, Paintshop-Pro or what else program you have.

    This result I used as the Bump texture. But you have to extend the limits. Values >20 are usable.
    The simple plane has got only 1 devision, so saving memory and render time. smiley

    That looks neat for a man-shaped depression. But is it possible to 'deepen' the depression to make it look more like a hole? Did you try extending the limits and using values above 20? :) 

  • JazzyBearJazzyBear Posts: 805

    I would just copy the mesh now and put a black version sized(maybe 10% smaller and located properly to match the bump map above. It would have a bit of an edge from the Bump and then be black.

  • AndySAndyS Posts: 1,447

    I tried way larger values, but didn't see a real increase of the depth-vision.
    Please don't forget: Bump is only a "fake" displacement - it only tries to imitate the optical effect.

    To do that - for iRay - with displacement, your mesh must have a dense net of divisions / triangles fitting the necessary resolution. --> So very soon you need a big (at least 12GB) GPU card or good patience for render.

  • Oso3DOso3D Posts: 15,085

    Oh, another option!

    https://sites.google.com/site/mcasualsdazscripts/mcjelevate-reva lets you take height maps and apply them to create a morph on an object. For some reason it seems to work better than displacement, in my tests.

    It's been a long, long time but, IIRC, I made a neat 'anthropomorphic coffin' for P4F by exporting a low-poly mummy as OBJ or 3DS to TurboCAD, scaled slightly for clearance, and using the 3D Boolean tools to 'cookie cut' a clearance hole in a thick, coffin-sized slab. Add base and lid, trim to size, ornament for spooky sarcophagus...

    You could try eg Wings3D or one of the budget 2D/3D CADs...

    ==

    Sadly, I lost my sprawling CAD and P4 runtimes, most backups, WIPs and zips to a bad batch of drives that killed both my old CAD Tower and Browser_PC. I did salvage some stuff, but...

    Recently found a 'forgotten' slide-mount back-up drive, stuffed with 'Classic' freebies downloaded 2004/2005. Surprisingly, many are still around. A lot are now 'orphaned', their original artists not traceable, the 'rights' either unknown or 'restricted'. You may have noticed I've a call out to 3DZone, who've migrated from rDNA to Daz, about one such. A few of the famous Japanese sites, with documentation, were saved by the WayBack Machine. Others, bot-blocked, were lost. 

    Upside is I'm building a new, octo-core CAD Tower, will be loading TurboCAD Pro & Poser11Pro. Soon as I'm over this Seasonal 'Flu 'slough of despond', I hope to have fun.
