endlich mal ein kurzes knackiges Tutorial über die Godrays danke sehr :P sub haste auf jeden Fall :)

[@TheDizzyViper]

Freut mich dass es dir geholfen/gefallen hat :)

[@Lowenmensch408]

Great tutorial, really good to know the glossy mat and specular mat swap, it helped me a lot on a project recently thanks so much !

[@TheDizzyViper]

you´re welcome! im glad it helped :)

Thanks man for your sharing

awesome dude

[@YugiohRLDSWebSeries]

very nice and easy to follow tutorial! One question I have sir, how did you decrease the noise, the fireflyes? In the preview image there are none.

[@TheDizzyViper]

I used many samples, like 10k. also decrease the IG clamp

[@Nibbylol]

Yo Dizzy , where can I find a similar looking male character ? Do you remember where that one is from or how you made him ? Much love

[@jademj2187]

Nice tutorial , thanks bro

[@VincentWuAnimation]

How to fix the noise problem?

[@retsukage]

[@soulaschoolofhealingarts]

Thnak you bro!!!!!

[@7dollarburrito]

Thanks for the tutorial, Dizzy! Quick question for you. How do you get more clear looking fog volume? I'm currently animating a room scene and the fog volume spreads my light nice and even, though frame by frame it seems more like grain than fog. Is turning up my samples the only way? any tips?

[@TheDizzyViper]

You´re welcome! yeah that has to do with sampling, sadly octane is quite slow with Fog. What you could do: Increase samples (test it in region render by rendering it in that region till its not noisy, and have a look at the used samples), use AI denoiser, play with the GI clamp (octane settings) and adaptive sampling. Also if you use emissive materials (not arealights or daylights) it could help to increase its light samples (its 1 on default).

[@tritruong198]

nice man. Thanks

[@ArgoBeats]

Great one, man!

[@akbaragill00]

Wow.... This was actually really helpfull. Thanks a lot man :)

[@TheDizzyViper]

you´re welcome man :)

[@Azuniite]

Good tutorial!

[@3dmonkeybizz]

Thanks for the awesome tutorial. I have a problem and don't know if you can help. If I use a Turbulence FD volume inside an Octane Fog volume I get a nasty little border in the render of the limits of the Turbulence FD emitter volume, like a shadow!??? Do you know why? Thanks again!

[@TheDizzyViper]

Oh yeah have that with vdb volumes sometimes, but i dont know how to fix it, im sorry

[@3dmonkeybizz]

@@TheDizzyViper very many thanks. Now I know it is not my fault!!! 😂

[@TheEpicAB]

I'm trying this in a brighter scene with octane daylight but it seems to just create subtle haze, rather than rays. Weird.

[@TheDizzyViper]

Yes, you have to decrease the sunsize by alot. i usually use the smallest possible size when i want to have great godrays

[@omegared1979]

Awesome Tutorial :) THX :)

[@TheDizzyViper]

you´re welcome

[@void1719]

great tutorial, one question though. when i add an hdri evironment to the scene, it doesn't get dark and just remains the same. do you know a fix to this?

[@TheDizzyViper]

Hmm maybe its new in a newer version of octane. u can get the same result by adding a black color to the HDRI, instead of leaving it empty

[@baimakhan]

you can try just dropping its power to 0

[@MilaMiya559]

Nice job，help me a lot ❤❤❤

[@67scaryboy23]

Hello, very nice tutorial but I have an issue: I see the fog in the octane live viewer but when I try to render my picture, I don't see the fog. Do you know why ?

[@TheDizzyViper]

That seems weird, are you sure you dont have the Renderview (red lower dot next to the fog object inside the object list) turned off?

[@szabolcsagai]

Perfect, Cheers

[@TheSiimur]

For some reason this doesnt work, i tried putting it far in the distance but its barely noticeable.. :/ still sick tut

[@TheDizzyViper]

thanks! did you make it very small? and also, just to test it out. Try putting cubes into the volume to see if there are really no rays at all or its just the object that obscures them a bit. for example if you have multiple trees in front the ray will be much much smaller to an extend where they almost disappear

[@MilaMiya559]

I try this with a real simple screen,but the render is super slow on my PC with 1X RTX 2070

[@TheDizzyViper]

hmm thats weird. i did the tut on a single 1080ti. the image took 20 minutes to render, idk if thats slow for you. if it takes much longer than that (with the same sample rate) try increasing the light sample rate maybe and play a bit with the GI clamp

[@austinhollywood_5861]

i cant get rid of fireflies and grain to save my life. any advice?! thanks man!

[@TheDizzyViper]

Play with the GI clamp a bit, as well as the hotpixel remover. If that doesnt work: increase the samples of the light and in worst case, use the AI denoiser. But i think THe Gi clamp should do the trick :)

[@Kidizgraça]

Whats is your desktop setup?

[@TheDizzyViper]

Sorry, what do you mean?

[@Kidizgraça]

@@TheDizzyViper what is the configuration of your computer and how long does it take to render this scene? I'm researching the feasibility of C4D and Octane to invest in software and a new computer

[@TheDizzyViper]

I have a Work rig with a 1080ti, 24gb ram and I7 4790k that i use for working, and a Render rig with an RTX 2080ti (soon getting a second one), 32gb ram and I7 8700k. The scene took ~30 mins on my work rig (with one gtx 1080ti) without Ai denoising. It was i think 20.000 samples

[@Kidizgraça]

@@TheDizzyViper Render a video with 20 thousand frames in 30 minutes?

[@TheDizzyViper]

no no, 20.000 samples. 30 for one frame
