Cutout Opacity related clarity

in Technical Help (nuts n bolts)

I was playing around with "The Beach" product which had some fog thing. I was wondering how to reduce/increase the fog. And, I was suggested to look into Cutout Opacity.

Then, last night, I was trying to reduce the thickness of some pants, make it transparent so the legs become visible behind the layered clothing. And, this cutout opacity did the trick. So, is this what cutout opacity used for? Among other things, make clothing transparent?

Also, is this the only way to make clothing transparent? I am playing around with layers of clothing, and I want the lower layer to be seen through the upper layer. For example, if I am trying to put a shirt on top of beach wear, and wish to make the shirt see through. I bumped into this cutout opacity solution accidentally, and wish to know if there are more choices to work with layers of clothing.

    bascially, yes. Cutout opacity is basically the transparent setting. You can use it completely with the slider, or create a texture (black for full transparent, white for no transparent) and plug it into that slot to greater control.

    In principle CutoutOpacity should be used as its name imapleis, for cutting areas out. Translucence should be handled with translucence and/or scattering.

    @FSMCDesigns

    Thank you for confirming.

    Now, about this sentence. "create a texture (black for full transparent, white for no transparent) and plug it into that slot to greater control."

    I am already manipulating the existing texture of the clothing. So,

    1) Why do this. You have mentioned greater control (but I am already getting the desired result).
    2) How would I do this. Perhaps you can point me to a link or how to that I can read up.

    (also, unrelated, just saw your devianart profile. I saw that nature thing render with the deer and greenery. it says Iray and Daz. But I have never seen any landscape generator in Daz. Is that some product in the store or some separate software?)

    RH,

    "Translucence should be handled with translucence and/or scattering."

    I see. I will look into it in my next Daz 3D session. Thank you.

    Haven't looked at the specific render you're referring to, but this image was created using a product called UltraScenery:

    HTH.

    ETA: Should have added that there are numerous add-ons for it to produce many different ecologies and features than the one pictured. Check out @howiefarkes store here at Daz:

    Ah! yes. Ultra Scenery. Yes. This is what I was vaguely thinking of as well. I remember stumbling into this in my early days of Daz. Back then, I was still trying to figure out how to place cameras, so got confused and scared (about the complexibity of using this tool).

    Thank you. I will investigate further. This is exactly what i was asking about.

  • algovincianalgovincian Posts: 2,591

    I've bought all the add-ons, as well as these 2 products that I use for making so-called "hero" trees (close-up or featured):

    https://www.daz3d.com/ultratrees--realistic-tree-system

    https://www.daz3d.com/ultratrees--arboretum-volume-1

    Thge results speak for themselves. You'll probably want to read up on instancing in DS before using this product, and definitely want to make sure you have Instancing Optimization set to Memory before rendering (Render Options->Optimization).

    In my opinion, UltraScenery, and all of its many addons, is the most fascinating product family in the Daz Studio universe. I have never enjoyed any Daz product as much as UltraScenery. Add it to your wishlist, Jay! Browse through the commercial threads about it to see hundreds of user images. If you invest in UltraScenery, you will want to get the Accelerator for UltraScenery, which is a plugin that speeds up the landscape generation tremendously.

    I even started a thread where I describe experiments that I have done with it. https://www.daz3d.com/forums/discussion/408551/ultrascenery-experiments-and-experiences

    Back on the subject of the thread, Cutout Opacity, the discussion about creating a black and white image to use in the Cutout Opacity channel is referring to masking off part of the item and leaving the rest visible. Say for example, you want to turn long pants into short pants, or you want to make clothing look like lace.

    Hey, a flash sale was just posted. HowieFarkes store (UltraScenery) is on sale right now.

    Thanks for mentioning the Accelerator, @Barbult. I forgot about it, but generating the scenes is extremely slow without it due to the complexity.

    Cutout Opacity is just a socket for an alpha mask. You (and by "you" I mean the person who made the product) create a black and white mask in Photoshop or wherever, plug it into Cutout Opacity, and the black areas will become see-through. If you have a shirt shader, you can create an alpha mask with rips and holes, and that will punch holes in the texture without having to edit the original.

    @algovincian

    Thank you for the additional information. The Ultra Scenery is added to my wishlist and once I am done with my current Daz Todo List. Ultra Scenery is definitely on the agenda.

    @barbult

    I am afraid, these sales are too tempting and it seems like this month is some sort of a "sale" month. Back when I was still a Valve's Steam customer, I bought an endless amount of games on sale and never played. Since then, when it comes to digital products (or even real life), I fix an amount every month, and come what may, never go beyond that. Dont want another steam situation.

    Yes, glad you pointed out the sale, but, this month budget has been spent, I am fraid. UltraScenery will have to wait :)

    Yes, I am very interested in natural scenery generation. I explored Terragen, Gia (or was it Gea) and was looking to use them. But, Ultra Scenery is good enough and I dont need to learn one more different tool. So, yes, the item is wishlisted and in the todo list.

    @margrave

    I do have photoshop which I use for Photography. I will try the mask thing and see where it takes me. Thank you for the additional instructions.
