3D Floor Plan

[glorybound]

I have to do one of those 3D floor plans. How do I render without seeing the ceiling, but the ceiling needs to block the sun.

I'm super curios about this too. I seen this done on the evermotion scenes. but the few I purchased there was no examples on how they did it.

It has to be easy. I was thinking the camera clipper, but I need these at a South East orientation.

use the VrayClipper, and turn on Camera rays only

Just set it to not visible to camera but leave cast shadows on.

Now, that makes sense! Thank you!

But, on an angle that would not work.

It should work fine but keep an eye on GI contribution. What you might need to do is make a copy of the ceiling object that affects GI, so you don't get lighting issues. Should work ok though.

Edit: here are a few we did recently: http://atelieryork.co.uk/Buckley-Building-Axonometrics

What do you mean? If the camera is on angle?

The VrayClipper is a separate tool from the camera's clipping plane function. But yeah, setting objects to not be visible by camera is another great way to do it.

I'll work through it, I am sure it's pretty easy; I see them all the time.

I usually use the slice modifier. I make a copy of the walls with the ceiling attached. I apply a slice to both remove top of one remove bottom of the other. Then the one I removed the bottom on (top of walls) and in obj properties turn that non-vizable to camera. That way it still casts shadows and I get a black top of walls which I like. Vray Clipper may be quicker.

Turned out to be pretty easy.



I set the ceiling not to be visible by the camera and left shadows on, exposed the camera for the exterior, and added a large v-ray light over the entire inside. Also, I capped the outside wall.
