  • Bend on an extruded spline causing lag in viewport

    This may just be the way C4D works but I have a hard time believing I’m throwing too much at it after seeing what some people do with the program..

    I’m trying to use a bend deformer on a “film strip” spline which has been extruded. I then move the film strip up along the Y axis so it goes through the bend deformer and gets bent. When I select the film strip and try to move it or spin the view around the object, C4D lags and then everything turns to box outlines during the move. Same thing if I select the film strip and play the animation in the viewport, box outlines. If I use openGL for the viewport, it does a little better but not much.

    I also tried this setup with a simple cube and everything is fine. In order for the film strip bend to work as expected I had to use “subdivided” intermediate points for the spline. I’m guessing all these intermediate points are causing the bog down, but I can’t figure out another way to make it work.

    I’m attaching a simple scene file if someone could take a quick look. I mainly want to see if C4D reacts this way on other computers. Is there a more “proper” or efficient way to produce this effect? Would a better graphics card help the lag issue? Are there any settings or preferences that might help? Is this just the way it is?

    I can live with this performance, but this is only a small part of a larger scene I’m working on, and it makes the animation/testing process a lot slower. It also scares me to think of working on a really complex scene if I’m having these issues on such a simple one.

    Subdivided for Intermediate Points is giving you way more points than you need in the filmstrip spline vertically and **way** too many horizontally (since you don’t need any subdivision that direction). Try Uniform 5 instead.

    Or try subdivided with a maximum length between 150 and 200.

    Wow guys, thanks for the quick responses. Both of your suggestions work with a little tweaking. You can probably tell I’m still very new to C4D, and 3D in general. Obviously I have a long way to go, but now at least I’ve just learned a little more!

    Thanks again!
