Filament project has been abandoned?

in Daz Studio Discussion

Hi everyone,

I'm encountering a problem with the Filament render engine in DAZ Studio. When I try to render hair cards that use alpha textures, everything appears transparent, which is obviously not the expected result. I’ve done some research and it seems like this is a known bug in the community.

My question is: does anyone know if there are plans to fix this bug? Or is there any indication that the Filament project has been abandoned? I’d appreciate any updated information or temporary solutions to this issue.

Thanks in advance for your help.

    It may well not be a "bug" but some adjustment that is needed - Filament is drawstyle not a render engine, and is adifferent beast from Iray or 3Delight so some tweaking is to be expected.

    As for abandoned, the changelog clearly shows it is having work devoted to it http://docs.daz3d.com/doku.php/public/software/dazstudio/4/change_log

    but what happens with the alphas, it can't draw more than one... something is not right... they just need to fix that and it would be perfect for me... I get good results but the alphas don't load, It is impossible to make a hair card with filament... I would like to help but I am not a developer... I feel like my hands are tied...

    Are you talking about the z ordering? That applies to OpenGL too - fixing it would significantly impact performance, which isn't (or at least wasn't) deemed acceptable in a Drawstyle.

     I'm just trying to create hair cards in Filament, but the alphas aren't working. I really like how everything else looks, so it would be great if they could fix that and make it a priority so I don't have to leave the job half-finished.

    DAZ's implementation of Filament is incomplete - you'll likely need to wait until the next major release is out, there has been work done as shown in the changelog. I am one of those users who is hoping that Filament becomes more useful for renders/animations.

    slighlty off topic, but filament matcaps would be nice. I.e., just plain color matcaps, similar to smooth shaded drawstyle. You can kind of get some good detail/shdadows with the plain opengl and iray uber shader on the smooth shaded drawstyle but it leaves a lot to be desired.  Filament would be better.

    With opengl we have the multipass option which fixes the z ordering and gets transmapped hair to work fine. Perhaps the daz developers can do that for filament too, if this is the culprit. Let us know.

     I found an alternative with Cinema 4d, the viewport is similar to filaments but without the opacity bug. You just have to activate the opengl options in preferences for it to work correctly and the lights must be in spotlight.
