It took longer than I planned(I got delayed by a thunderstorm), and 
there are some problems with this release(crashes have been reported 
with the particle_system object), but it should be enough for you to 
play with the glow patch which seems so popular...

Major bug.  Whenever I render any scene with blobs in it MP+.31 crashes. :(
Here's the error code:

MEGAPOV05APLUSMOD031 caused an invalid page fault in
module MEGAPOV05APLUSMOD031.EXE at 016f:0045807f.

I've pretty much narrowed it down to only blobs, though isosurfaces might
also me a problem.  Fix it quick!!  :)
Please?

Yeah, it'll do that. :( It was very apparent with the particle_system too.
That creates a bunch of blobs, doesn't it? Interesting... I'd recommend not
using 0.3.1 with blobs until someone figures it out.

I just tried out the new parameters of the glow effect and found them quite
useful.  There is much more room for variations now.  

Is there some kind of translation for the old syntax to the new? I tried to
achieve the old effects with the new version, but i did not succeed.  The old
one always looked more foggy.

Use "type" instead of "glow_type", the existing types have not changed. 
Use "warp {turbulence ...}" instead of "turbulence ...". Use "color 
COLOR*GLOW_AMOUNT" for your color, since the glow amount was dropped(it 
was 3 unnecessary multiplications per glow per trace, and wasn't very 
useful). Don't use radius, falloff_exponent, or size, not using them 
will turn them off.(and size doesn't work properly in all situations)

That should be everything...

Well, that tells me where to look for the problem with my 
particle_system...(which is actually a hybrid object using the blob code 
for rendering). I am guessing this is a bug that exists in MegaPOV 0.5 
and earlier versions of MP+ as well, it just didn't show up until I 
plugged some memory leaks.

Thanks, it works perfect now.

Hmmm... the only way I could get the new glow to work was by putting and
object (box{0,0}) at the end of the scene file. If I didn't put a dummy
object at the end of the file the error "object or directive expected
but end of file found instead" comes out even with just a camera and a
"glow {}" statement. Ver 3.0 allowed the glows to be rendered without
any other objects but a camera in the scene.

Regards,

Keith

That's because glows aren't objects. And, um, version 0.3 didn't 
consider them objects either, the same error would show up. In fact, 
some of the work done between 0.3 and 0.3.1 was to make them behave more 
like objects...it obviously wasn't complete, but they should now be 
allowed in some places they weren't before(in unions, for example). I 
still have to make them transform along with light sources and CSG 
objects, though.(maybe they should be attachable to any object...)

My best guess is that you were using glows in light sources before, and 
"naked" glows now. Since light sources are objects, that error didn't 
show up.

I'm hoping you can fix it before my time runs out for the IRTC. :)






You can, right?
