Surface Material Filter Not working. Tweet

Rajib. Its not hair. Its V4 colliding with the same V4.

Ah. Sorry, did not notice that.... The line in the forehead I get is generally due to the hair colliding with the head and in any case this happens whenever 2 geometry intersect and expanding one of them so that they don't collide kind of works most of the time. . hmmm... If you can select the Eyebrow mesh of V4 , under the Parameters Tab under the Eyebrow mesh do you see General->OctaneRender ? In that if you change OctaneRender:Visibility control to 0 does it help ?

If possible can you put a screen shot of the scene and parameters tab with the V4 eyebrow selected ? I don't have V4 so unable to check.

Rajib, the eyebrow mesh is loaded even though if you tick the mesh off in the Scene Panel. So there's nothing you can do other than trying to move the mesh out of sight. Octane will render it even if it is hidden for the camera or setting opacity to 0.
To me this is a serious bug as only god knows what else is loaded in a scene that shouldn't be there. Doesn't matter what you do as Octane will render it even if you hide it or not which also affect the rendering speed. Even more so if you try to scale objects down and move it out of the way. Found that out the hard way.

Ok, I downloaded V4.2 and made a render.

V4.2 base character render

Does this look to you ? There are no artifacts in the forehead. If this is okay, basically under Surfaces Material Filter remove everything and render. No need to set any opacity to 0 etc. Default Visible off works.

[rajib]

With the Surfaces Material Filter empty, lets say you enable the visibility of the 1_Eyebrow and lets say color is set to red. This is what I get :

1_Eyebrow visible, Opacity 1, Red Diffuse

Now if I set the Opacity to 0 in the material, there is no eyebrow mesh shown

1_Eyebrow visible, Opacity 0, Red Diffuse

So basically keep the Surfaces Material Filter empty:

Surface Material Filter should be empty

That way whether the 1_Eyebrow has visibility off in the scene tab / Visibility is on but Opacity is 0, it will not create the artifact in the forehead.

Hope this helps.

Great. So now you need to make the meshes intersect.

Well if you see my above post, you can see they intersect. Here is the actual wireframe view from the Daz Viewport.

No, you need to turn the eyebrow so it goes through the head. Then they are intersecting.

Why do you need to turn the eyebrow ? Isn't it supposed to appear over the eyebrow area ?

In any case once any 2 geometries intersect, you will get artifacts. There is no solution for that. That is how Octane behaves as far as I know.

Because head morphs will usually intersect with the eyebrow on V4.

And to the intersecting problem. That is what I already mentioned earlier. The problem however could be fixed easily if the plugin did NOT load the eyebrow when it is set to be hidden in the Scene Panel. For most other objects the plugin respects that. But in this case the plugin ignores that and load it anyway.

Personally, I just set the scale of eyebrow to 1% and move it to -2 along Z axis and problem solved...
