    Hy there,

    I use the GeRayCollider to "RayTrace" an Object. Now it often happens, that within the same polygon a ray does not hit. That is, I have constant collision length, the same ray-direction and just a really small change in the position of the ray-origin. Then I get a FALSE from the GeRayCollider back and the next ray-cast, also just a tiny bit further, will again get me a TRUE on the collision.

    Is there something I am missing? Any way to tweak the accuracy of the GeRayCollider? Or is the problem a different one?

    Thank you,
    maxx

    Any news on this one?

    I can reproduce the problem, but I can't see any dependencies yet. I am just trying to figure out, when the Collider will fail, so I can fix it ...

    Thank you,
    maxx

    Ok, thank you. I try to break it down, so I can extract some code to show you the problem. Somehow, the Collider seems to work in certain cases, then again fails. Reproducable though.

    Can I send you an example project, if I can extract the problem? Do you have an email-address or do you prefer another "way"?

    Thank you,
    maxx

    A simplified complete project would help. Please send to sdk_support@maxon.net.

    I wasn't able to isolate it yet, maybe its another problem then. Don't spend time on this yet, as I am not sure anymore that the GeRayCollider is guilty ;)

    If I succeed with isolating, I'll come back to this ...
