I am rendering an animation that makes use of Blobby and found several cases that makes aqsis to crash.
The cash seem to happen when a blobby cross the plane of the camera, at a early stage of render,
Blobbies that are near of the camera but does not cross the plane will do aqsis to hang without rendering anything after several hours, even for a very simple scene.
So, my test case is a Blobby segment that goes from -1.0 to 1.0 in the Z axis, and have a radius 0.5, so the blobby surface will extend from -1.5 to 1.5.
When the camera is far (0,0,5) the blobby is rendered correctly
Moving the camera to (0,0,2), near of the blobby, will increase the render time, but sill works.
Moving the camera to (0,0,1.5), even near of the surface. Will hang aqsis.
Moving the camera in a way that its plane cuts the blobby will drop a "Floating point exception". This happens at (0,0,1.4) , (0,0,1) and even at (0, 30, 1), Moving the camera in the Z range 1.5 ..-1.5 will end always with a crash
I attach the example with camera at (0,0,1), which will crash aqsis. Please, move the camera to points given in the report to see the behavior at these points.
