View Full Version : Surface: Hot Metal Cattle Brand

08-27-2009, 10:00 AM
I am trying to get a cattle brand looking really hot. Anyone have any techniques to share to make white hot metal? I've been messing with weight map driven gradients with some procedural texture, but all I seem to get is a lumpy bomb pop that glows on one end.

Any assistance is appreciated.

Can you post a render?

Gradient in the color and luminosity channels

Gradient in the color and luminosity channels


And I'd do the typical black body colors - dark red to a bright glowing orange / yellow...

I agree with Splinegod, gradient and weight map.

Attached is what I had come up with initially, using a weight map to drive luminousity and color. I was looking for a way to add some more detail, maybe by adding a procedural on top of everything to make the object less uniform. Note that the attached image has had Corona applied, and probably too much of it. The gradient also needs some massaging.

I think I'll hop into ZBrush and paint a displacement map instead of messing with procedurals as it'll give me more control.

Thanks again for all of the responses.

I'd say add some procedural noise to the gradient and you'll be done.

I wouldnt let the hot metal go to white.
I fast photshoped your image and i out it more yellow, and a brown halo around.
Maybe some GI would acomplish that, and a bloom/corona. i dont know.
