    Can vertex colors be used to drive transparency levels for hair cards? Inner most geometry = less transparent?

    We support the Alpha channel in vertex colors, so yes you could probably use it for hair.

    Can I change vertex color setting per object?

    Not at the moment. Can you share more about your use case?

    Thank you reply :)
    In my case, I put my textured character (it has vertex color too for Memo)  to the simple pedestal it colored by the vertex coloer, no UV.

    then, I use vertex color setting, My textured character bleed the memo vertex color on texture.

    So, I just want to turn off that character only.

    Interesting, thanks! It's probably not something we're going to implement on the short term.

    However, I believe we use the "multiply" blending mode to mix vertex colors with diffuse/albedo/base color, so if you make the vertex colors white everywhere that you will have a texture, it should not affect the final color.

    By the way, I notice you're using quite a lot of post-processing filters on your models. These filters are very "expensive" in terms of model performance, especially Bloom, SSAO, and SSR. In this model, for example, the Bloom and SSAO aren't really doing much for you, so I would recommend disabling them: https://sketchfab.com/3d-models/celen-beat-covid-19-fea6d1aa9aa94457826721be6db58008

    thank you for reply and advice.
    I turned off those. Tuning those effects are super fun, so I might did too much. XD

    Haha yes they are. I think we all tend to be a bit "trigger happy" with the filters :)
