Redshift Volume & Fog Tutorial
HTML-код
- Опубликовано: 16 сен 2024
- This week we look at how to create atmospheric lighting scenarios with Redshift. First we'll have a look at how to create a light that will affect any volume, then how to create and atmosphere and finally we'll discuss a few different scenarios like ground fog and how to set them up.
**Please Note**
I forgot to explain what 'Phase' does - essentially the further you push it in to the positive (toward a value of 1.0) the more the atmosphere will appear behind your objects. The opposite is true when pushed in the negative (toward a value of -1.0).

Glad to see more Redshift stuff on youtube...this engine deserves it!
Yep I'm a big fan too!
i know it's quite off topic but do anyone know a good website to watch new tv shows online?
@Bentley Darwin I would suggest flixzone. You can find it on google =)
@Bentley Darwin lately I have been using flixzone. You can find it by googling =)
Real informative tutorial, thank you!
Do you know how to go about creating this fog inside a specific volume, for example could I fill just a cube with this fog?
you got any answers or solution?
Great explanation. I'm curious if there is a way to tell a mesh to not affect the volumetric fog. I have some meshes with transparency, but they affect the fog, which looks weird. Is there way to block the fog from affecting individual meshes?
i found it this is very useful in 2021
Good to hear it's still relevant!
very well explained!!!!
+Ashish Shenoy thanks!
How do I see the icon for the light in viewport? It's very dificult for me to select the redshift lights in the viewports since they are not represented by any icon .
+Ross Daniel this is usually a graphical error due to the graphics card in your computer. You can get around it by switching the viewport from viewport 2.0 to one of the other options or in your Maya preferences changing the viewport renderer to or from open gl to direct x
Can you have both redshift and renderman installed on maya at the same time without issue?
Sure can, well at least I've had no problems - Maya 2016, RM21.3 & Redshift (whatever the latest version is).
thanks!
Great tuto, Do you know, how to get a png render with transparent or alpha channel ?
If you're saving it out from the Render View window just set the file type to .png it will have a transparent background by default as long as you aren't using an environment style light (like a dome light with an hdri image). If you are using a dome light in the attribute editor for the light scroll down to 'Environment' and uncheck 'Enable Background'. Above is applicable to batch renders also.
do you manage to get nice results using meshLight with redshift Fog ? because in Arnold I have good results using both together but can't get similar result in redshift.
Hadn't tried it till you mentioned it but I ran a quick test and it's pretty ordinary, a lot of large noise in dark areas. Not sure if there's a limitation with mesh lights combined with atmosphere would have to ask in the forums.
Further to that, if you're in a pinch I'd suggest applying a Redshift Incandescent shader to the geometry seems to have much better results.
found solution to my problem on redshift forum, I haven't switch on the 'Bi-directionnal' option
+Alexandre oh cool thanks for the info!
I have a question. Can we use toon/ cel /cartoon (whatever) shader in redshift?
There is no built in toon shader for Redshift however I believe that someone made a plugin a few months back, you might want to google that.
@@SmallRobotStudio thank you so much 😁❤️
@@SmallRobotStudio Actuallly i found a week ago gnc rs toon shader by gary crabe but i cant setup... I'm gonna die for headache.. If you know how to setup can you help me? PLEASE...
Afraid I've never used any toon shader so I'm not going to be much help. Alternative in Maya is the software toon shader however that's not GI or see what Blenders options are if you just export your scene as an alembic if you. Any get it done in Maya
Will a physical sun affect Atmosphere?
Does the Volume Scattering work with HDRI lighting? Everything gets blown out for me ahaha
It does but your hdri will be illuminating all of it which is why it's blown out, the volume scatter is global.
@@SmallRobotStudio Hey thanks for clarifying, and so quick too! :D
FIRST!
And in 3ds max? how i make this fog?
I don't use Max so I can't help you there.
***Please Note***
I forgot to explain what 'Phase' does - essentially the further you push it in to the positive (toward a value of 1.0) the more the atmosphere will appear behind your objects. The opposite is true when pushed in the negative (toward a value of -1.0). This is due to the fact that the light is being reflected away from the camera when the phase is increased and toward when it is increased.
handy! thanks a lot michael.
No worries mate :)
