This is Iray? There was a change for Filament

Fixed the amplitude of bump maps in the Filament (PBR) DrawStyle

in 4.14.0.7

yeah the only issue I have faced is trying to render in iray with Filament viewport, simply run out of VRAM

I usually switch to bounding box anyway if rendering in iray, the lowest viewport setting to tax my card the least as even openGL textured uses a fair bit of VRAM so not really an issue

Looks like this filament introduced a lot of new crashes into Daz.

  Most of them happen when you try o switch rendering engines, and typically attempt to use iray and filament at the same time will  need badly so if you are trying to do final rendering or want to use iRay viewport preview you can have a filament running or open at the same time 

although it is quite strange that filament manages to run faster than opengl for some reason

The advanced openGL is slower to render on my PC than an iRay render.

I am getting my Filament crashes just switching from whatever viewstyle in the ViewPort to Filament. It also doesn't matter what I have the actual renderer set to either: 'Viewport', iRay. 3DL, switching to Filament in the Viewport crashes DAZ Studio PB 4.14.1.22

This isn't universal.  I've no issues switching to the Filament draw-style in the latest public build, at least with the simple scenes I've tried it with.  My DS is pretty vanilla, though.  No Octane, or anything.

quick comparison between the 3 engines; filament is very quickly (around 5 secs) but many shaders need to be adjusted as pointed out by Mec4d

thx for your hints Mec4d, maybe with some tone filters to be used in post within D/S (LUT, Reinhard or such..) we could adjust the outcome; in my bief experience shadows may vary a lot by moving items up or down, left or right, and if you scale them down, shadows look more accurate almost always.

anyway filament is a good idea but pretty unusable currently

Could you use the filament rigged shadow joined to a character? https://www.daz3d.com/dforce-sy-rigged-shadows-filament

Not all functions under tonemapping working in Filament, but what you can do is adjust the ambient light higher (hdri) and lower the value of the direct light , it may improve the overal effect of the contrast and smooth out darker shadows.

Also you may adjust proper the texture channel for the models especially the reflectivity as I mentioned before in this thread , it may reduce the contrast effect on the darker textures as right now it absorb light little too much , make sure you not use 3DL shaders on the imported figures . Even if the colors are too white or too black in the textures you can still adjust the appearance , for too dark black  you can use higher reflectivity level and roughness at 0.70 to fix it,  if your enviorment map is too dark there will be nothing to be reflect on the surface than the specular from the Distant Light creating higher contrast .

Distant Light shadows are not fixed yet and I still have issues no matter the scales .

It is not bad at all for the first time , but you can make it better with a little adjustments , good practice for the future :) and I know it is not easy to adjust the 3D scans textures as I have couple of them myself and had to create additional mask maps to get things looking better . 

But you are on a good path already so try to adjust the environment intensity first and reduce Distant Light value to see if your contrast got adjusted and maybe that's all you have to do.

thank you,

well, for some reasons maps seem not to be influenced by gamma correction so contrast is too dark and colors too vivid; maybe acting on hdr images "ex ante" that could be tweaked or adjusted; correct, the figure is a 3d scan.

Is there a way to modify the shadows projection dome or whatever? need to scale the scene every time to get proper shadows

No, only the Filament and Iray drawstyles have shadows. I would use more than one 3D view in the Viewport, with one left/right, one front/back, and another for Perspective. Switching to wireframe or hidden wire can help too.

Nice , if the black level on the models clothing and hair was proper it would looks very good , little too dark for PBR and it take away , are that 3D human scans ?

The filament preview window consistently crashes my DAZ Studio Pro Public Beta 4.14.1.22 for the scene I have used to make my avatar. It's actually done so pretty consistently on prior versions although I did manage to get it to filament render a few times on the 2nd released of the 4.14.x public betas that have filament.

There was a minor update which was mostly bug fixes I think.

However, Filament supports shadows from the first 6 lights and i'm kind of pretty sure it was first 3 before (maybe). Though maybe not.

Ah. Okay. Thanks for the info, and replying.

For such a small update, it's totally messed up my installation, and content library. :/

It might just be my imagination.. but hair does seem a little better looking (less flickery anyway).

But gah, installation issues are always a pain.

Take some mo-cap, add a fun model and background, then render with Filament and poke at it post-process. Came out ok, well maybe I got a little crazy with the auto-lens flare^^

Thanks for having a look!

Nothing changed since last time Cutout opacity still the same , and there is no reason for changes . Your graphic card or driver may have impact

also when you using Filament and Cutout opacity , make sure you don't use. empty space , or you have something in the background, or enviorment map , or a single plane 

I tested some time ago things out , I used bad alpha map for the Cutout opacity , it was not 100% white everywhere on purpose , but once there was another model behind , things started looking totally better 

of course some hair you using may have normals issues as I experienced with a single sided twisted grass , but having something behind your model also will allow you to see better stuff like Glass etc.. of course without the refraction effect as it is not supported yet, as always better ghost shadow than nothing . 

In the image below I used alpha maps for the cutout opacity that do have lower level of gray not just pure white and black , when using green sphere behind it looks so much better , it may help you in some situations

Remember Filament is PBR , it needs enviorment to render stuff proper or at last a 3D object behind it 

the second image with HDRI Draw Dome On

Note: you should use proper maps under Cutout Opacity , but in case you don't have it as the product you got had old style maps , set the Draw Dome On at least

I was bringing transparencies color images in base image and black and white image in cutout in from Photoshop and they did not work, now they do.

Maybe I was doing something wrong, as if that never happens.

Another thing, lights are bright in Filament. Is there a setting to make Filament less sensitive to light but not effect my Iray render view?

Yes. That is what the Filament options node is for. Add it from the Create menu. Lower the ISO setting. MEC4D recommends 0.56 and that works well for me.

Excellent! Thank you Barbult!
