You are very welcome. Usually one is fine with GGX Energy Preserving. I think its a "The more you know" situation 😄

A masterclass in pedagogy! I'm not a C4D user, but am always here to learn from how you teach and pick up any tips that are render engine agnostic. Thanks!

Raphael thank you for this..its very tech-y but its who you are. I love you for that ! 2 week ago i got pissed so much on octane that i've decided to shift to RedShift I am nearly there. watched over 150 hours of top shelf training and i am very excited on the power of RS. Hope you switch to it soon .

Hey Vladan, thank you for your comment. I use RS too on a (more or less) regular basis for my job. So in terms of "switching" I am actually using both. Though I prefer Octane for my work 😇 If you want great RS tips I can recommend: www.youtube.com/@gernge Its a friend of mine who recently started making RS tuts!

@@SilverwingVFX checked your friend's "RS tweak section". From the overall experience every case scenario is going to have its own settings. There is no magic button in any render engine. Thank you and wish you make some RS tuts on AOV's.- but your way - i mean all the way..

Awesome, was looking for a long time for this info! what about when using maps for each channel? Does it make any difference if using octane's default or GGX?

@SilverwingVFX

Жыл бұрын

Hey there and thank you very much for your comment. As I show in the video, there is a difference in roughness from the Octane to the other BSDFs. A texture is just driving the roughness vales as the slider would. Just with a different (slider) value for every pixel. So in other words, yes Octane will give other roughness values vs the other BSDFs using the same texture. If you are in an PBR workflow, the go to is usually uses Energy Preserving GGX. So if you want the intended result from those textures, use Energy Preserving GGX. Hope that helps 🙌

@@georgeluna6217 Yes, GGX Energy Preserving is a very foundation. As I said in the video, there are some minor exceptions. But in general you can´t go wrong with GGX EP. No matter what material type.

It's "Student's t-distribution". More important really.. the bell shaped stuff you posted are probability densities (PDFs) and not 'BSDF' and mainly, the Y axe is not 'reflection strength' by any means... the top of the curve for example represents a mirror reflection probability.. so let's say roughness is zero, the whole curve will be just a straight line pointing to the top (ie. an impulse aka a Dirac).. meaning you don't have any other probability to shot other directions than a mirror one.. then the higher the roughness the fatter the curve .. meaning the range of directions is increased and different directions have some probabilities to kick in.. of course the more directions the less reflection strength because more stuff is sampled (ie. in your examples.. not all directions will sample a light.. producing the visual falloff typical of specular highlights).

Hi there. My bad. I should have called it Students-T Distribution! Other then that your answer is 100% the same I am explaining in the video. I made the decission to not show curve distributions of varying roughness because it might be more confusing for newbies. A text box is explaining that it´s a fixed roughness level in the video.

​@SilverwingVFX I have to nitpick the name because so I'm able to introduce you to the real story of the distribution.. it's Student's t-distribution.. 'Student' was the pseudo name the original author used instead of his own... then using a capital T or not it's up to you.. till we agree on the final meaning, that is .. the T distribution of Student. The long story has to do with beer ! W. Gosset was the original author but he was working for Guiness and Guiness prohibited to publish stuff with own names because of NDA. Eventually he determined the distribution actually while he was doing quality control in various stages of the production process of Guiness beer ! There would not be a STD distribution without beer probably ! Cheers 🍻
