Radiosity problems

[furby3D]

Hi,

I’m having some problems getting to grips with radiosity and rendering, and I’m wondering if someone can help me.

I’m following this tutorial here:

http://download.blender.org/documentation/oldsite/oldsite.blender3d.org/122_Blender%20tutorial%20Radiosity.html

But despite following the instructions, I get very different results.

Here’s my model when I click ‘collect meshes’:

So far so good. But I click on ‘gouraud’, then on ‘go’, and this happens:

Which doesn’t look right. If I click on ‘face filter’, it does smooth things a bit, but the final render just doesn’t look good:

Any ideas? I’m sure I’m missing something simple but I can’t think what. I’ve sub-divided the model a few times to smooth it out, clicked on all the ‘smooth’ buttons I can find - but to no avail!

I can post the .blend file just before the radiosity gets calculated if that will be of any use to anyone.

Any help is much appreciated!

Many thanks,

Matt.

Bon Jour. Msr. Henri Gourand created that lighting model for low-poy models. see http://en.wikipedia.org/wiki/Gouraud_shading Based on the plane and the light and the shape of Suzanne, it does look right. Try using a Solid lighting setting if you want her to vue smooth.

Thanks, but it’s still no better:

I just can’t get it to render smooth faces like in the tutorial I posted above:

I’ve followed all the instructions, but I must still be doing something wrong for it not to work!!

My .blend file is here: http://thegrapevine.brinkster.net/images/b1.txt (rename it to ‘b1.blend’).

Click on ‘collect meshes’ then ‘go’ and it produces the blocky results I’ve been getting.

If anyone can fix it so it renders like the second image above, I’d be very grateful. Otherwise I’m stumped !!

Many thanks,

Matt.
