amazing. Thank you
@@pascalcreativedesign8790 My pleasure!
Very useful indeed! Another thanks here from me :)
Very glad to hear :)
saved my life omg, thanks!
Haha.. I wish I were that good! Glad you found it useful :)
Very useful!! thanks!
You're welcome! :)
Thank you so much!
My absolute pleasure!
I don't know if this is the right technique, but if you want to apply it only to the specific lights everyone is talking about, what about a technique that lowers the Volome of Visibility for the other lights?
Very good point. But the tricky part is that visibility is mainly on and off option. But maaaybe there could be a way to use Arnold to add more control.
I'll look into it this week!!!
I can't render the gobo with my gpu only with cpu and it's super slow is a solution or is it simply unsupported operation for gpu rendering?
Oh snap.. sorry to hear. I won't be surprised.. but I'll check for you.
Oh wow didn't expect a reply on a video that was released 9 months ago 😅Really appreciate it tho@@ihabiano
@@user-cf4ou6vw3c you bet!
@@user-cf4ou6vw3c Alright, so apparently Arnold GPU lacks the support for Alpha images, which is the essential part for light gobos, sadly.
One option I can think is to make the gobo physically and put it in front of the light like gobos get setup on real lights; lame solution I know but it might do the work around it.
Too bad it doesn't work on gpu, I'll try your solution tho, thank you so much! @@ihabiano
I try to use the same settings, I cannot get the light lights up the scene, when I turn up the exposure of the spot light.
You do not want to only rely on the God rays light. You have to get additional/basic illumination from other lights; generally.
my spotlight isnt showing in the arnold render
@@tind_0 Happy to help if I can. But givve me more or maybe more technically-explained info please.
Like, you have other lights that show?
Did you make sure the scene is rendering as normal?
Did you try cranking up the Exposure and intensity just enough to illuminate (if cranked too high they break and crash the rendering completely).
@ihabiano it was mb lmao theres a whole "arnold" part in the attribute editor thats where the correct setting for the exposure was I found it thanks
@@tind_0 in your defense, it's set up in a terribly confusing and non-intuitive way. It's Maya's fault honestly. That's why it's a relatively long tutorial to cover all those aspects.
Glad you figured it out!
hank you so much for this video! I was wondering if there is a way to have some lights with the fog and some without it ?
My pleasure!
Unfortunately Arnold doesn't allow a mix. It's either/ or kind of scenario.
how to light the rest of the room?
You're interested in learning more about lighting in general?
iam also having the same question.. when i put more lights to rest of the room its also shows fog @@ihabiano
@@shathrukhanan5596 yes, that's normal. Once you bring in fog, it'll be applied on all the scene.
The beam with the light-gobo that specified the god ray here only limits the fog.
You can add more lights for sure but know that the fog is not specific to one light, at least in this case. Does that help?
Any other questions let me know!
is there any way to apply the fog on for specific light@@ihabiano
@@shathrukhanan5596 before Arnold, it used to be that way, which was convenient.
I can investigate ways around it sometime next week. I'm also thinking that if I still have the scene, I may make it available if that helps?
