Ok, so I have a high tech spacecraft (see picture pelow) that needs some flames:
So what do i do first? I start by adding lights inside the boosters to make things look a bit more realistic. (NOTE: if the lights lie even slightly out of the boosters, they will look more like lamps than flame lights!) If you have many lights (as in this example) you may want to hit Ctrl + L, and link their data. This will change all the lights when an alteration is made to one of them.
Now what? We now add meshes that match the shape of each booster and extrude them backwards:
you also should select each individual part (you can do this in edit mode with Ctrl + L), go to side view and UV unwrap it with project from view (Bounds). Now we can give it a material. The properties are as follows:
Transparency : Z transparency alpha 0
Texture mapping: UV, flat
Texture influence: Color enabled 1.00, Alpha enabled 1.00
I checked the option ‘ramp’- my ramp is as follows:
You can customize your ramp depending on your style. I also added compositing nodes for the final product, you may copy these if you wish:
Your finished flames may look something like this:
That is all, thanks for reading! If you have any thoughts about the spaceship, critiques about the flames or anything, feel free to leave a comment!
