    You give the VIDEOPOST_CUSTOMLENS flag for your videopost node in GetRenderInfo(). Then C4D will send MSG_VIDEOPOST_CREATERAY messages to you. Simply cast the data parameter to VideoPostCreateRay and set p/v depending on x/y.
    If this doesn't work, please tell me what fails so that I can investigate further.

    Hi!
    I tested VIDEOPOST_CUSTOMLENS flag by making a camera similar to cinema4d perspective camera and there are some diferences in rendered images. Looks like the antialiasing is somehow lost during the CREATE_RAY process...
    The test was really simple, only received x/y converted to perspective and the set p/v.

    Hi again!
    this is my code for message function:

        
        
        
        
        Bool Message(GeListNode* node, LONG type, void *data) {

        VideopostCreateRay *vpcr = (VideopostCreateRay * ) data;
        
        
        
        
        LReal x = (vpcr->x - width/2.0) / xFactor;

        // convert altitude and azimuth to vector form
        
        
        
        
        LReal cos_alt = cos(alt);
        
        
        
        
        y = cos(azi) * cos_alt;

        vpcr->p.x = camera_x;

        return TRUE;

        return TRUE;
        
        
        
        
        }
        
        
        
    

    this code works perfectly if antialiasing is set to best (16x16), otherwise object edges become aliased...
    can someone please help me... I don't understand why this is happening...

    Does everything else than Best 16x16 equal None in the AA settings or are the edges just less AA'd the less AA you have set in there? Could you post a complete ray creation algorithm (not necessarily your real one) that shows the problem? I always got somewhat decent AA when I tried.

    According to the developers VIDEOPOST_CUSTOMLENS will always force the Best AA setting (same as with QTVR, since no projection of geometry edges is possible). Could that be what you're seeing?

    Probably...
    The AA Best 16x16 or no AA both make a perfect render. But using other options all the edges suffers from aliasing...
    It isn't very perceptible but he problem is there...
    I don't known if you already seen this problem nor if it possible to solve...
    Other question, is possible to invalidate one ray in MSG_VIDEOPOST_CREATERAY?
    By other other words, don't render one specific ray, or give it a color, like black.
    thanks

    Hi all!

    I may have found a bug on CUSTOMLENS, when I set 2 planes, one in front of the other, and the nearest is transparent, the ray generated by CREATERAY doesn't hit the far plane!

    I think this problem is in CUSTOMLENS code, since transparency seems not to be honored...

    sdk version: 9.5

    Thanks

    Hi again!

    Ok this problem has been solved in this new release...
    In 9.6 CUSTOMLENS works fine!

    Hi all,

    Again one question about CUSTOMLENS, when I set this flag on my code the post effect "lens effect" simply doesn't render anything...

    Is this supposed to happend?

    Cheers,
    Marco Silva

    Yes, it seems like some post effects will not work with a custom lens. I've passed this on to the developers. Thanks for reporting!
