Wheat field on fire that slowly spreads

Hi,
Can you please tell me where to begin? We need wheat field that caught fire and spreading. All the mesh will be imported from 3ds max. Like in this video Fire in Weld County field - YouTube

I just need fire line that is spreading the rest will be animated in itoo forest. Thanks

Hi there,

One thing I would recommend first is to familiarize yourself with the software by looking at the provided presets and understanding how they work. This may also inspire the artistic direction of your fire as well. Let me know if you have any questions about achieving that!

But how do you make fire slowly spread ?

You can create a primitive shape like a cube and use it as an emitter, and then keyframe the scale of it to match the speed at which the fire grows. I would try that first and see how you like the results!
