-How do you make a glow,halo,lighting effects? Light source or energy source that, in the source, there is a noticeable white glow.
You could either:
add a spotlamp and turn on halo and set the halo step to 1 for cool volumetric light effects
add an icosphere, make its material emitting, select all meshes, go to the radiosity panel, click collect meshes, and click gour, then click the big “go” button (if the green dancing calculation takes too long, press escape to stop it). Then click “replace meshes” (unless you want to see how it looks before making some changes, in which case click “free radio data” to make your scene editable again. This is a completely static calculation, so only use it for still scenes.
