    Hy there,

    transparency can be an issue…..
    What software did you create the 3D Data with?

    if you work with 3d Max this is what you should check.

    Make sure that the background colour of the Diffuse Image has the about same color as
    what is shown ….with the grass make it green like the grass etc…
    Also make sure thet there is no glossyness in the shader ( Best use the Legacy Shader)….just make the colours of the specular, Diffuse and Ambient channel black and play with the self illumination……
    also check the order of the transparency in the objects or better define the transparency as a mask…
    this works best with simple plane based objects as in your scene

    Greats

    thanks for your suggestions! i created it with blender.
    the issue with the grass is solved by eliminating all blues in the texture. :good:

    the grassfield with dandelions is one object which can only have one definition about transparency. i could split it up but it seams to be an issue with orientation of a transparent plane aswell. if you turn the see you will notice that the “dark” transparent planes are not visible form all views.

    my settings:
    object with transparency; blend mode auto, double-sided, depth write, depth test
    Verge3d; FXAA, OIT

    thanks for any suggestions!

    hy again,

    just make the blendmode as a mask and put some self ilumination on the material…
    that should do the job…that way its not depemding on ypur light settings…( which explains the different brightness on both sides of your objects….and kill the glossity or whatever its called in blender…..)

    Ceck my site for some samples i work a lot with transparencies…with the coorect settings it really works well

    disable it.

    Puzzles and JS coding. Fast and expensive.

    If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

    that’s an OIT issue…

    it should work this way https://v3d.net/1885

    strange, your sample looks awesome!

    this is what it looks like if i disable OIT and set AA to auto with depth write off on the objects.
