View Full Version : What is the best way to make & animate a simple candle flame?

Maybe there is no such thing as a 'simple' candle flame, but that is what I'm trying to animate. I am still a noob, but I've tried Hypervoxels over the last couple of days. Sometimes I get close, but the still have the spherical shape and the color and transparency isn't right. Should I model the flame and use displacement? Any suggestions and guidance would be appreciated, thanks.

A basic teardrop shape with a weight map that masks out the displacement would be fine. The tip should displace more than the base.

For an easy glow effect, locate the "glow" setting in surface properties, set it to ~50%.

Then, in Layout, click Windows (upper left corner) >> image processing >> click "enable glow". The settings for that are global and affect all surfaces based on their glow percentage.

The Y scale channel could be adjusted with a noise modifer in the graph editor along with displacement. I want to make a candle now. That could be a challenge to do wax and all

Heres an example done pretty much as described. The flame is displaced geometry. The glow in the candle is a gradient in the luminosity channel.

Damm! Nice job, Snosrap. :bowdown: Thanks, I'll try and find the scene and post some details.

Thanks for the suggestions. I've tried some but without success. I had the flame moving but it was jumping off the candle. Funny, but not success. I'll keep plugging away as time permits. I think I need to research some displacement tutorials and such. So much to learn, so little time. Thanks again.

First, I would videotape a real candle and map it on geometry.

I found the scene. I swapped out the candle for a low poly proxy. For some reason my smoke won't render. It renders in VIPER only. It's an old scene so maybe it's not compatible with LW11 or something else I'm missing. Hope this helps.

Thanks Snosrap. :thumbsup:

I know it's your scene and everything, but have you tried turning on Hypervoxels to get the smoke?

Would never have thought of that, nice idea.

I downloaded a video of a flame and put it on a billboard poly for the candle in a jack o lantern.

How would one accomplish this?

thats crazy

Depends on how detailed you want to get. Example of a single image to simulate a 2d candle flame.

By adding just a little more geometry to this flat plane, you can animate it so it doesn't look as static. Pretty much the same method could be utilized for inserting live video of a candle into your scene. Note that unless you have Lightwave set to display transparent textures in modeler/layout, you won't see the results of masking transparency without rendering (I have no idea why this is the default... setting yech!).

It would be deluxe to set the candle polygon to always face the camera on the Heading channel: then the camera will never be edge-on (horizontally at least) to the "flame".

Vertically, you're hosed. :D

Snosrap,
Thanks so much for sharing your candle and flame. I've never used skelegons, so your scene file is fabulous. It will be a great learning tool for me. I also didn't think about modeling the way you did, it makes perfect sense now. Thanks again.

Go figure.:D Here is the scene without the HV's being hosed.:screwy:

No prob. The latest scene I uploaded also has the HV smoke straightened out. :thumbsup:
What the heII - here's the candle too.:D
