Title: Neb opacity
Post by: ShadowWolf_IH on July 29, 2004, 02:54:48 pm

would it be possible to adjust the opacity on a full nebula?  Not sure if we could do this in fred or not......0 would be the way the full nebula currently is, and 100 would be fully opaque and the nebula wouldn't be seen.  In between those numbers would set the opacity percentage.  Not sure if this is feasible or not.

You mean 0 being transparent, and 100 being pea soup?

no i mean the other way around...0% opacity has no effect....100% opacity you see no nebula.  What you arte thinking is Neb strength....0 is transparent....100 is the soup.
either way is cool.

...But if you're in the nebula, and you see no nebula...? I'm confused...

stop over analyzing......not being seen is just a reference point.  i doubt that anyone would ever set it there.

You've got it backwards Shadow.

o·pac·i·ty  n. pl.
--The quality or state of being opaque

o·paque  adj.
--Impenetrable by light; neither transparent nor translucent.

Thus, with 100% opacity, you shouldn't be able to see ANYTHING :p

Doesn't really matter which way the slider goes now does it?

It'd be really nice to be able to set this though. Also, maybe having no nebula background could be cool too, so you could just add some light fog to a mission...

you're using opacity as meaning the same as transparency, while in fact opacity is actually the opposite of transparency.

ok....cause i was just going by how it works in Photosuite....don't blame me for fallowing in the footsteps of thier mistake

For this to really useful though, you'd have to throw out the existing nebulas and institute volumetrics.

It doesn't matter what you call the slider. Which way it goes is important. I wouldn't want to see a repeat of the brightness slider :D

Can't you simulate this with alpha values?

WMC: almost certainly

I've posted about this before - there are three areas to consider with the nebula

The background texture
The "poof" cloud texturess
The visible distance.

Make a nebula with poof that are entirely black (ie they're invisible) and you'll see there is still a definable view distance. (this disppear even though there arent any clouds).

This is the value we need a adjust. Adding an alpha layered tga poof will just add to the options, not increase visability.
