radiosity, huh?

Can somebody why when radiosity is enabled, it does this, sometimes?

See image http://staff.bath.ac.uk/abshhkc/03.jpg

 

Because it hates you. No particularly good reason. It is just mean and
spiteful.

Or

You have too much light in the scene.

Options :
turn down the lights
turn on automatic exposure

Or

something else.

It would have been helpful to tell us why you thought the picture was wrong.

 

I've never experienced this myself (so far at least....) but I've heard
about the "red renderings". IIRC, this is usually caused by one particular
object (ground plan would be a good first guess).

First, check all your settings, if that doesn't solve it then I'd render
just parts of the model at a time to narrow down the culprit.

That reminds me a bit of the CPTMC building on the Bath campus, is it?

If you want information on radiosity you could do a lot worse than post this
question to alt.binaries.3dstudio & alt.3d.studio there's a wealth of
knowledge regarding rendering there, including ACAD software, Brazil, Mental
ray etc.
Just take the time to let them know it's ACAD your talking about and the
fact that it's a shade OT and I'm sure you wont get flamed. Things are
really quiet in alt.binaries.3dstudio at the mo so I'm sure they would
welcome the attention

Well, In the 3d program I use (Art of Illusion), the textures' emissive
settings would do something like that. I'd turn them completely off and then
check all the lights- their number, proximities to the object, and levels,
etc. I'd also check the immissiveness and reflectivity of the surroundings,
surrounding objects and background, etc.. Oh, and maybe the camera settings,
too, such as exposure, filtering, blur, etc..

It is the CPTMC building at Bath Uni. You're from Bath?

 

I can fix this "red rendering" problem by reassigning materials to my
objects.

More often, I have one or two objects/layers appearing in red after
radiosity calculation. However, the image you saw, everything was red.

I just assigned, reassigned and a bit more until the red stuff's gone.
It's a chore and some times, I have to do this material re-assignment
many times before the redness goes away. It's a pain in the asssssss.

It only does this on occassion. It think the first reply was probably the
most accurate..., it hates me because I've been slagging off acad2004/viz
lots.

Sort of

I'm a freelance technician - done around 9 or 10 months work for the estates
dept on campus untill about 2 months ago.

Did a scheme for an underground rifle range out by the bobsleigh track which
fell through :-(

And worked on the new School of Chemestry & Biology building that's down by
the South building, and a whole bunch of other bits and pieces.

So what's with the CPTMC model - just a handy something to model - can't
believe they want to modify it already !!!!

What do you think of the new sports training thing??

Good to hear about your fix.
I am keeping my fingers crossed that a co-developer follows through with
writing a script for dxf import into Art of Illusion so that it can manage
the lighting, textures and renders, etc., and even some of the modelling
that are begun in other, often more CAD-based, programs. If successful, it
could blow the program wide open for use by engineers and architects, etc..
Here's a chap who seems to do most of his work seen online using Art of
Illusion. He also appears to be entering some contests and winning some
online awards for it, too.

And the main developer's response:
" Ok, I'm impressed...
You clearly used a real 3D program for making that image, not just some
cheesy piece of freeware. "

Visited your web site and read some of your tutorials, well done that
man.....

Can I add your web site to my AutoCAD Links Page please
