View Full Version : How can you make star filter highlights?

Is there any way to make a star filter effect that globally affects all specular highlights in LightWave? I'm trying to do a still image with gleaming chrome.:confused:

If it is a still, you could always do it in Photoshop. For an animation I would create a separate render pass and use Knoll Light Factory. If you want to do it Lightwave, there is only one tool that can do it to a certain degree - Lume Tools. I'm not sure however if there is a current version for LW. The Corona filter that comes with LW will only do more or less a glowing effect.

Thank you. I'm experimenting with Corona now. Wish I could use the effect selectively with lights. But what is really upsetting is that when I click on the "Light Intensity Tool" on the Light panel, I can't get it to shut off. There is nothing in the (poor excuse for a) manual about turning the damn thing off.:mad:

Do you go to GI and set Ambient Intensity to 0?

You could try this plugin: http://kaniserver.homeip.net/~konoha/psycho/Plugin/PG_SCat.zip

Corona is relatively simple to use for sparkling star hilights...

Just create a star image (grey scale, or colour if you want) in Photoshop, and use it as a texture in Corona. I often use the 'Specular shading' input to do my Corona.

I think I posted something up about this on the old Forum system... Hold on and let me see if I can pull it up... Hmmm, no, its simply about corona for glints on steel... But maybe its useful?


Otherwise, generate your texture, apply it to your corona and render away! Though that PG_ plugin that Captain LightWave mentioned looks very cool! Have downloaded it, but not tried it yet...

The PG-plugin IS cool, but unfortunately it's only in Japanese for now, but I have e-mailed the author and offered help on translating the whole bunch....it's up to him/her now if we'll ever have a "readable" version.

Thanks Capt. & Kevman. I'm going to go with the plain corona effect for the job I'm working on. It looks great and the star filter would be too much, but I will check out the plugin and the texture applied to corona method for the future.

The After Effects plug-in "Starglow" by Trapcode ($99) will do exactly that - especially cool for animations. Once you've tweaked the glow to your specifications, just render a single frame.

Thanks Ooga. It looks like a great solution. I bookmarked it for future reference.
