  • Another Frequent Crash Problem – HELP!

    Posted by Jason Connolly on April 26, 2005 at 3:41 pm

    Hello the COW! Any thoughts anyone can lend, please chime in.

    I have a master scene with about 10-12 floating tv screens(each one has a video clip playing). I zoom the camera into whichever TV is “talking.” Each zoom is a sub-scene, each sub-scene is between 3 – 6 seconds. Simple enough. The TV screen is a simple, flat polygon. To that polygon, I’ve applied a video clip to the color channel. I click animation, click calculate. I repeat this process for each screen. I have about 12-14 lights added to the scene, with 2000×2000 shadow map applied to each one. However, when I render, C4D crashes(locks up) frequently mid-render. In the bottom of the render window(where the render status appears), it seems it’s locking up on a shadow map. So, I turned off ALL the shadows, re-rendered, but still get the same frequent crashes. I’ve even re-exported all of the video clips(with Animation codec) thinking it might be a corrupt video file, but still get the crashes. All of my video clips reside in the Tex folder. That’s all I can think of…if you need more details, just let me know. I’m running out of time, and I’ve sold a client on this concept, so if I can’t do it this way, I need to find another way. Thanks! Jason

    I’ve uploaded the scene here if it helps(without video of course):

    I looked at your scene file and it seemed fine, and without the source footage
    acted like it would render reliably on my mac. Here’s what I’d try: First, render as a targa sequence,
    so if you do get a lock-up, you can pick up where you left off by noting the frame number in the render folder. you can always reconform to QT later using AE or quicktime pro, etc. If the lockup happens at the same spot every time, I would suspect the QT footage may have a corruption issue.
    Also, in earlier versions of C4d, I had issues with texture names that were similar. Sometimes the
    maps were assigned to the wrong models and all kinds a crazy results. As a last resort,
    you might rename your QT source files to distinctly different titles and reassign.
    Of course, none of this is good news, but it looks like a good lookin scene.
    Good luck

    THanks, bear! Yeah, the TGA sequence tip is a good one! Question: How does does one go about allocating more RAM to C4D in MAC OS X? Do you know?

    Not sure about that, although I thought that RAM assignment was a thing of the past in OSX.
    Anybody else know if there’s a way to allocate RAM in OSX?

    Yes, I thought the same thing, but at this point, I’m throwing everything out there!!

    Have you got AfterEffects or Combustion? If so the way I do this is to render out as an RPF file and just put all the VT in when you composite, it’s very simple. Basically I’d assign a composting tag to each screen and give them all a different object ID. Remove all the quicktimes and just replace it with a flat colour (black). Remember when you render to RPF to select the options and add ‘object id’

    When I then load my render in to Combustion I just select the ‘texture map’ plugin (under 3d) select the object id and assign the relevent quicktime in the ‘layer’ box. Do this for each screen, you will have to render out mattes for each screen to put them all together over the main render.

    The best part about this is you can slip and change the clips as you like without having to re-render the 3d constantly
