what's up,

i've this scene (see ref. image), i'm rendering with MR.
Now, the ship lights are spheres with a color material and glow effect.
Is it possible to have this glow effect to reflect in the ground and the ship it self?

Maybe it shouldn't be a glow effect?

can someone give a hand on this please?

thanks

like i know, the glow effect in mr is a post effect, this means, that the glow effect will be calculated when the scene rendering is done, so it is impossible that mr can catch the glow for the reflection, the glow isnt present at this time.

ok. so that means i need to set that up somehow using lights instead, right?

thanks

you can do such light glows in post (constant shaded sphere and then in post add a blur to the sphere), or, you can try to use point volume lights.

1. assign a shader to must-be-glow object
2. open the color property of this shader
3. goto HSV mode
4. upper V value more than 1... for example make it 2 or 1.7

lets render

after this i need to go to post right?
i increased the value till 3, got a nice color but no glow.

i think i can take it from here in post.

thank you all

yeah, i realized that.

i also tried to mess with light glow and fog but with no luck as well.
i'm a noob in maya so my words are not to be taken too serius but, glow effect only rendering at the end don't make any sence in my head right know! :(

"I have not try but some thing connect with ctrl_objectlight by francescaluce can a glow effect"

thanks
