I used adamthwaite's muzzleflash prop and I thought that I will need to make the muzzle flashes glow up a bit to compliment the point light that is illuminating the rest. So I changed the prop's ambient color to yellowish light, ambient value to 1 and highlight size to 1 (see image).

But there is no obvious change to the muzzleflash. Help please.

Muzzleflashes are best done in post work, using a program like After Effects.

But if you want to do it in Poser, what I would suggest is playing with the transparency. I don't see much by way of transparency in your settings. But that's only showing the preview material of the muzzleflash--what do the other surfaces look like?

For a muzzleflash, you want the hot gases of the core to be white and the corona to be amber and semi-transparent. You may be able to accomplish this by duplicating the muzzleflash, scaling it up, changing the colours to amber/orange, and ramping up the edge transparency.

Actually the pic you can see above is a Poser 4 render already.

...so if i change the transparency values, the muzzle prop will glow? I am not sure but the muzzle prop looks like has some sort of transparency already as you can see the barrel of the gun is still visible behind the flashes.

I will try duplicating and scaling as you suggested to add some "coolness" to it. I'll be back tomorrow for bed seems to be so invitingzzzzzzzz........ZZZZ...zzzz....

some versions of Poser have a 'point light' (or something to that effect) that you can move in 3 dimensions (the source of the light, not the direction). If your version supports that, make a small one, hang it over the barrell, color the light to match the muzzle flash, and that might do it.

Thanks alot.

Now that I've had a chance to sleep on this, here's a few more suggestions:

Have a look at this site: http://fxhome.com/muzzleplug/

This is an After Effects plugin that we're looking at using for muzzle flash effects in our own films.

But that's not what I want you to look at. Take a look at the flash video embedded on the page, right near the end of the clip from 0:23 to 0:34 or so. There are a set of sample muzzle flashes shown there that you can use as a guide for what a cinematic muzzle flash should look like.

You'll see what I was referring to when I mentioned a white core with a coloured corona.

A muzzle flash is unburned gunpowder burning as it exits the muzzle of the firearm, and so it incandesces. Depending on the intensity of the burning, the colour will vary from white at the core/hottest spots, to yellow/amber to orange on the corona. The transparency varies with the intensity. But it is never darker than the surroundings. If you look at your render, you'll see dark spots on the muzzle flash that are darker than the background.

The way that muzzle flashes are done in other 3D programs, or in compositing software, is to use additive transparency, where the colour value of the transparent object is added to the colour value of the background objects, moving the transparent colour closer to white.

Poser doesn't use additive transparency. So, we have to cheat and there are a few options.

1. The first is transparency.  You can use a very transparent copy of the muzzle flash with the edge transparency turned right up to add something resembling a glow, but it won't be a true additive glow. Still, you can go a long way in the materials room towards getting something that is close to a glow. I played around with it this morning, and I got some okay (but not great) results at Transparency 0.6, Transparency edge 1.2, transparency falloff 1.5 and adding in full ambient and full translucence (coloured yellow), but it was still far too opaque.

2. I'm thinking that sub-surface-scattering nodes may give some promise, but it would take a lot of playing around to get the look that you want.

3. A particle system, like Daz's Particle 3/PZ may be able to give you the quasi-volumetric effects as well.

But as you can tell, my first choice would be to "do it in post."

Glad to see that you got it!

Weeee!  :D
