    Hi,
    Regarding the VR controllers, I have a shy question. Is there a way to trigger the vibration in the controller, for example, during the hover-over event or other events? I assume one would need a plugin for that. I haven’t found anything about it in the forum.

    Thanks Tom

    The webp file I created was very rough. Meaning I did quickly masked out the white and did not take any time creating a clean mask. Which is why I used Alpha Blend. Using Alpha Hashed can cause the original color (in this case white) to appear in some spots. But for the most part it should look good.

    JPG Hair cards are not going to work well so you will want to separate them into an alpha based image format. There is nothing wrong with using Alpha Blend to get the effect you want…its probably the most simple solution for you as you can just separate the white hairs in the image using tools similar to tonal range selection.

    If you have a technical reason for using Alpha Hashed and you do find colorization you don’t want…you will find that if you colorize your files from black and white to black and the color of the hair you want..then alpha hash will work without creating the white but it still should be on a separate alpha layer. The white areas are the blending areas between the color edge and the mask that are not able to be clipped by alpha hash.

    Attached is the webp….i didn’t pack it in the blend file.

    Thanks a lot Xeon, I will test it with new better clip maps and will compare
    results in PC Browser and later in VR.

    Nope. Looks quite good.

    ok, thanks for testing. So it might be something with my clip map. But good to see it’s possible.

    I looked at your blend file and made a modification to your haircard_clipmap.JPG

    Just as a general its best to use an file format with an alpha channel (.PNG, .WEBP). You will get predictable results.

    I took your file….separated the white out and created a new .WEBP and applied it to your model.

    As you can see EEVEE, EEVEE render and V3D look very close.

    Project/Blendfile here: https://v3d.net/t91

    Hi Xeon
    Thanks, it looks better now with your solution.
    I didn’t check the file format because clip maps are mostly delivered in .jpg format
    and work well with most 3D Applications.
    But a very good hint. Thanks.

    Alpha-Hashed also results with white borders right? Maybe it’s not possible to use for hair cards.

    I told you to attach here .blend with the head and hairs as an example. What did you do? You attached that useless image ))) You think that somebody in hurry will start modelling those hair cards to see what’s wrong with them? :unsure:

    sorry, I thought I did… here it is.
    It must be zipped, that’s why :-)

    Nope. Looks exactly like in Blender. See no difference at all. And no issues.

    Yes, alpha blend looks in both more less same, but not ideal for hair cards.
    Alpha-Hased would look much better like it’s displayed in Evee , in Verge it looks wrong.

    Image 3 and 4 are alpha-hased

    Hi
    Attached a simple head with a simple hair cards object an a clip map.
    As you can see, the Alpha-Blend mode is some kind of strange transparent.
    In Evee, Alpha-Hased would look ok, but if you make a sneak peak or you publish
    it has these white edges.

    Any help is appriciated.. maybe alpha-hashed is buggy?

    Can you post the image file you are using or a sample of it?

    Hi Xeon

    I will setup an example scene with blender file tomorrow.
    I hope there are some tricks to get some more beautiful results in respect
    of the strange transparency.

    Make the material double-sided.

    When I need to use textures with the alpha channel I use these parameters for materials making them look exactly like in Blender.

    Hi kdv
    Thanks for investigating.
    I did make the material double sided and used your settings above except GLTF 2 Compatible, this would look like Opaque Mode.

    Here you see what I mean, when the bun facing the camera, it’s some kind of transparent.
    I know, it also needs a hair colored scalp, but I think there is something strange.

    And if you try with Meta Quest, it’s like inverted. But in Meta the Alpha Hased works.

    Alpha Blend usually gives the best visual result. In your case disable “Depth Write” in the material properties.

    hmm, after testing it also in bright environment it still looks strange, like it‘s not double-sided depending on some view angle.
    Best would fit Alpha Hashed, but it shows some white edges.
    Are there some good results with hair cards and verge3d?

    No. Check FPS in AR…

    If I don’t move it’s mostly at 85 fps, when I move around 77 fps.
    It seems the marker is tight on the floor, the character is slightly in the floor, it looks like
    floor interect with it’s hip.

    Now it’s hard to miss the cursor ))) It’s green.

    True, thanks!
    The tracker is good to see, and the group of farmers aswell.

    Is it also jittering in your headset? Even the single farmer sample jitters if I walk around.
    Things in VR are better tracked or look better tracked.
    But maybe that’s the nature of AR vs VR… I’m a complete newbie to this, but I already could build a cool VR World. :-)

    The character will be visible only after clicking on the round cursor. Do you see that round cursor tracking the floor surface?

    Funny, now I see the cursor and can click and there is the character.
    Did they change something? Or maybe it’s after a Meta Software upgrade.
    Now it seems to work. :yahoo:

    I really didn’t last week. There was all odd in the headset.

    Thanks !!!

    But the blue move around button is very close to the eyes.
    Is there more interaction than just place? After placing I can’t move the character around.
