I'm not having any luck with making halos. I've included an earlier
posting by Johannes Hubert on how do it and how I've followed these
directions. Can someone tell me what I'm doing wrong or just not doing?
In short:Create an object that is to contain the halo.
---1 each cylinder scaled x,10 y,10 z,1 rotated x,90 and placed in the
background with a light behind it.
Make it "hollow"(and everything else that contains the object, including
the
ground-plane if you have one).
---Its the only thing but I made everything hollow just incase (just the
cylinder at first then everything).
Create a texture, add a halo component to it, adjust the parameters of
the halo component as you need them, assign this texture to the object.
---Okay this is where its gets trick for me. I made a texture and
assigned a halo to it but I'm not getting anything when I render the
picture. At first I just assigned the halo and got nothing but a black
sphere when i previewed it. I then added a solid color (white) pigment
to it and made it 100% tranparent (I don't want to see the cylinder just
the halo) and I get nothing at all when rendered. I've played around
with the type, function, mapping and all the other attributes and so far
can't even get a hint of a halo.
Voila!
---Not yet but soon hopefully.
Please help.
Thanks, Steve.

Hi Steven!
So I guess I have to elaborate, sorry for my short post the first time...
But really, actually I think the post wasn't too bad, because I think you
did everything right, only that you probably ran into a bug in Moray:
>At first I just assigned the halo and got nothing but a black
>sphere when i previewed it. I then added a solid color (white) pigment
>to it and made it 100% tranparent (I don't want to see the cylinder just

Correct, I forgot to mention that.
>and I get nothing at all when rendered. I've played around
>with the type, function, mapping and all the other attributes and so far

I guess you didn't change the density function. It seems that there is a bug
in Moray (I will notify Lutz anyway): The "constant" keyword does not get
exported to POV-Ray. If you define a halo with a density function other than
constant, you get your halo! If you need to use "constant", then it seems
that you have to hand-edit your code after export (I tried that and it
worked).
Hope this helps a little bit more!
Johannes.

Thanks Johannes,
It works like a champ now. I thought I had tried everything but I guess I missed
that part.
Your help is GREATLY appreciated.
Thanks again, Steve.

This thread is yet another that showes the great need for enhanced documentation.
Some of us need more examples, and more tips and tricks. Thank god we have Johannes
for now. Maby he could expand the docs and get a free registration! :)

Too late :-) I have sent my registration to Munich even before the beta-test
was finished!
Anyway, I would have to dissapoint any hopes of me adding to the Moray docs,
because all my spare time is taken up with my own TreeDesigner project.
Greetings, Johannes.

Hi Allan Middleton, you recently wrote in moray.win:

Well, part of the problem is to seperate where is it a POV-Ray problem
and where is it a Moray problem. Apart from the bug about constant not
being exported, it isn't really part of Moray's job to document how
halos work. But I do agree that a simple tutorial about creating one
would help here. Unfortunately there are only so many hours to a day
and so many things to do.

100 % agree. Would be the same to force any company producing a compiler for a special
programming language to add a 'new user quick learn' tutorial to the language too.If
someone knows how to handle *.POV files by hand (or brain) and is able to read the PoV
docs, he/she will (of course) find some features not implemented in Moray, but never
ask for a good documentation.

:)Keep working on the next version.
The ones complaining about the missing docs are (most probably) not the ones buying
the
next update... ;)
BTW: Thanx for this one...

A note to Lutz: I realize that you are very busy right now and I would not hold up
progress
but please keep the docs in mind over the next few months/years.

I paid for version 2.5 , I paid for this version and I will pay for future upgrades.
Good
work deserves reward.

Right on!

Learn something new every day, I do...! And I always thought you programmer types
worked 24hrs a day, and only on software. Don't tell me you *need* sleep! :-)

Hi Larry Bourdillon, you recently wrote in moray.win:

Well, we do program a lot, but unfortunately on 'real' contracts that
run on a deadline, not on Moray. I wish I could work full-time on
Moray, but it's not do-able.
