    strange shape

    Hi
    Till now I made a few bootle and jar, and sometimes on upper part of model is something strange. i don't know what. Example below:



    It exist independently of angle of camera. Below You can see my glass setting. And I used fast freshnel too. But with and without the result is the same.



    Any suggestions?

    The arc of the offending item obviously follows the geometry. Is the mesh clean as in no n-gons which shouldn't be there?

    - "w" then select >4 polys + to see if.

    No. The geometry is clean. It was first what I cheked.

    Try "m" and "shift i", then check your stats "w" for 2 point polys. You won't see the problem in wireframe.

    It was second thing what i checked
    "No points eliminated" and "No polygons eliminated".

    I chcecked geometry very carefully. Its clean for sure. For me something else.

    Interesting thing, from fprime renderer, the jar looks good. Without any shape.

    Is the Jar and the cap one shape? Because if you want nice refractions you need a closed shape. that means if you applied 2 different surfaces to one model your refraction won't look right.

    To get nice realistic glass, use the "Dielectric" node.

    Ok, sorry missed that. Some part of the inner geometry is overlapping the exterior?
    Can't quite make it out in the wire but it looks a bit tight at some point. If you have the "inside" faces poking through the outside the various channels will just do what they do.

    You mean are together? No. Glass of jar is one shape (closed). The same cap. Its one shape. On the glass poly is applied one surface.

    No. The surface of the glass has a thickness of 1 mm. maybe looks a tight, but is not. I still dont know why this happened. I resolve this problem in Photoshop now But it irritates me, why this is happening )

    Any other ideas?

    You're welcome. Indeed, so will be easier

    I just checked the "exclude from vstack" button for the glass surface and it disappeared. Not sure what that would mean though...it's just the first thing I did

    ... layer 3 had some stray points to merge. It also appears to be that which is striking through layer 1. Moving layer 3 aside removes the glitch, as in it's in the geometry

    Wow! Ingenious!
    Really works! But how? What for is that button? And this mean that geometry is ok?
