Hi Dethblud, The flames are simple objects in fact . Vertex here but you can use spline of metaballs aswell . The effect comes from the shader tree . You can see that the object is fully transparent ( don't forget to check "no light interactions ..." ) . In the glow channel, two colors ( marine and ocre ) were mixed with the elevation plug-in from DCG, that's all . Hope this helps ! Show us your image when it's done ! litst
