View Full Version : Simple way of Rendering Cutaways?

03-02-2012, 07:15 AM
Hi , I have a model of a 40 foot truck with an exhibition inside of it.

I want to create a cutaway of the truck but I don't really want to boolean the model as I need to do some renders of it as a complete truck.

I know I could create two models one cutaway and the other not and I could make certain polygons transparent but I wondered if there was a quick way of creating and rendering cutouts a bit like using the section tool in Google Sketchup.

see the video example.


Can anyone help please, many thanks!!!!

Hi... it's not the best method... but here are a few


mid-way down the page, look for clip-map cutaway with a Trex... or you can check into DP kit boolean here:


Good luck!!! Hope some of this may help

you might could use an animated boolean. That way your object doesn't have to actually get cut, just at render time. I think DPont has a node that does this. Haven't used it or know how it should work but something to look into maybe. Good luck.

In application which has modifier/history stack, making such tool would be a piece of cake..

DP's boolean shader can do this although it can be a pain to set up. If it's for a still I'd render two passes and manually erase the outer layer, I find that it offers more flexibility.

Modo's latest release does render booleans natively and they look brilliant.

I don't think so. ;) I don't think that NT has the same inferiority complex that it used to and I'm sure that most people can see both applications for their merits and weaknesses without thinking that they must use one or the other exclusively.

LW can do this natively with nodes.
