Thanks Stephen, after my first attempt at modelling the ant I thought 
maybe I should revisit Sculptris as it seemed like something I should be 
doing with meshes. However, I like the challenge of just using SDL to 
create images.

Thanks Norbert, you are selling yourself short I think but thanks for 
the compliment. You could be correct regarding the cause though as it 
seems to be related to the HDR part of the image.

This is starting to look like it is related to the HDR probe, if I just 
use HDR the issue is present stil but if I switch off HDR and use a 
regular light source (no other change to the scene) the SSLT effect is OK.

Have you tried a more blurred version of the light probe?

I wouldn't be surprised though if you were in the process of discovering 
a bug in the integration of radiosity and SSLT; so if you don't mind 
digging a bit more, you'd do me a great favor.

As someone cannot get blobs to work the way I want them to work. I can 
only gasp and stare. With admiration.

Hi Clipka,

Going to show my ignorance here but how do I blur the light probe?

Happy to help in any way possible, I tried a different light probe and 
had a similar but more uniform problem (attached). I am happy to upload 
the source if that helps or run test renders myself. The light probes I 
have tried so far have both been from the same source so I will try one 
from a different source.

Both the probes were from http://www.hdrlabs.com/sibl/archive.html the 
backyard and harbour3 ones towards the bottom of the page.

They can be tricky that is for sure, the legs were actually a lot easier 
than I expected (just translate the components along a spline and adjust 
the scale at certain points) it was (and still is) the head that is 
giving me the most trouble, once the model is complete I will upload it 
to the objects or source files thread.

It is probably something that just comes to you. Too bad I was behind 
the door. When that knack was given out. ;-)

That would be worthwhile. :-D

HDRshop is probably the best tool for the job.

Uh, that definitely looks wrong. Can you do me another favor and use 
that same light probe but with (a) a simple sphere, and (b) a 
single-sphere blob?

Dang, forget about that one. It used to be free some years ago, but 
apparently they've made it payware.
