Perspective section.

[joed200]

Hi there,

I want to produce a rendered perspective section through one of my buildings. Could anybody give me some tips on how I can set this up in max or direct me to some examples?

Thank you,

Joe

The easiest is to set the camera up where you want the view to be and then set up clipping planes in the camera. These will cut the model at 2 specified locations (near and far). The catch with this one is that you'll have to clean up the cuts in photoshop because they won't appear solid.

Clipping plane approach is a sound one, but it has the limitation that the section will be perpendicular to the camera's view, another way to do a section is to use the "Slice" Modifier, and where it works you can use "Cap Holes". The Cap holes modifier can be a bit unpredictable depending on the geometry, but where it doesn't work you can fix in photoshop, (filling in where it should be solid).

 

Here is a section we did a few years ago, which needed to be rendered in many passes and ended up with a fair amount of paint also.

Good luck,

Thanks to you both for your help. I will give it a go and let you know if i have any problems. That section looks great by the way!

Ok I have played around using the slice method and was just wondering how you would set up your lighting to obtain the same results for if the model had not been sliced. Sorry for the poor explanation.

Do you mean so that the external lighting does not affect the internal spaces? What you'd want to do is make a plane that covers up the entire cut plane and make it not visible to the camera, and so it doesn't cast or receive shadows. That way it will block the exterior lighting but not show up in the rendering
