Title: Complex falloff
Post by: Studio Heisenberg on 2017-05-08, 22:35:48
Hey guys, I am having trouble to get complex falloff looking exactly the same as we can make it in 3ds max, with direction type etc... I have attached solution from vray for cinema 4D which have some of the options, but one with all these and curve inside would be great. Thanks in advance :)

I am sorry, but I don't know what you're talking about... You are having trouble getting complex falloff look like in 3DS Max where? For what? For IOR in refractive channel? I'd love to help you, but I need more information :-)

I have made small pdf file where I explained it, take a look in attached.

For what its worth... I second this. Falloffs in general can be a bit of a pain (depending on what you are doing I suppose) in c4d compared to 3ds max.

Aha, so the request is to duplicate the 3ds Max native Falloff map, and create something similar to Siger Shaders ComplexFresnel map, just for clarification on the feature request? So not a request to duplicate features from Corona in Max.

Well, I think You can take benefit of Cinema 4D's interface and make it even more powerfull than in 3DS max with Cinema's layering sistem... It is really important for Fabric creation, and most of all for Layered materials as mask... And at the end there is so much excellent artist that discovered some awsome material workflows and sruff inside 3DS max and Corona, but we are not able to translate their workflow to Cinema 4D because of this difference....

I'm "thirding this" - would help massively when doing metals as others have mentioned.

Alright, I understand now. So it's basically  two requests, right?

First one is better falloff shader with more options - here it would be ideal if you guys would tell us what features you would need the most, because we don't use Cinema on a day-to-day basis the same way as you do, so we cannot really tell what's important.

Second feature then would be complex fresnel equations? This is a change that would need to be done in the Corona Core, so it would probably take some time to implement.

What I would personally like is a 3ds max replica - You can define a type (perpendicular / parallel etc...), you have a mix curve with which you can blend the A and B color and then possibly an output curve where you can basically control the actual values with a curve.

If you guys could get that going... that would be sooo useful... wow! :)

Falloff shader is more important than second one, but it is nice to know it can be implemented later on. For the first one I agree that 3DS max method is really nice, and just to mimic that inside of Cinema 4D would be great! Thanks :)

Thanks guys! I'll add this to the feature requests list.

Hi,

Really looking for some nice falloff features in Corona (GrandRamp, Falloff, Ramp) with Interpolation, Direction type with IOR and texture options and so on....!

I am not seeing these some important features in C4D Corona Roadmap, I hope it will be added till its final release.

... and in bonus, if Car Shader can be separate material with flakes that will will be like bread with butter...!!


Thanks.

Yes, you are correct. These features have not been planned yet.

Afaik you can create and map your custom IOR in 3ds Max using the Falloff "node" plugged into the IOR map slot. If I recall correctly its there.

So basically the functionality is probably there already, the only thing that needs to be devised is a more advanced falloff shader in C4D that can be manipulated using curves. I think V-Ray for C4D is doing something similar.

Innocent question (i swear ), why not use max?

I wouldn't switch to Max just for a shader or a plugin, even though I have experience with it. Something different should offer real magic before I switch.
People get used to their tools, have invested in them, built their own libraries.
Sure, you can do pretty much the same things with different applications, be it Max, Maya, C4D or Modo.
The familiarity with the software basically defines the efficiency of one's workflow. People also have deadlines or no time to learn something new.

Let's take ZBrush and 3DCoat, for example. I started with ZB, even though it doesn't have such a nice clean and intuitive straight-forward workflow like 3DC and I bet a lot of things could be much easier in 3DC. (Re-)topology, UV- mapping, per pixel painting in multiple channels...
I don't even use C4D's sculpting tools for that reason.
There's nothing I can think of that I couldn't do in ZB/C4D and I know exactly what to do.

Unless there's an insurmountable wall that I cannot climb over, I have no intention of switching. Due to my experience, there's always another way or more or some yet unknown trick to solve the puzzle. Sure, I've banged my head more than once against the wall but that has led to a better understanding of the software or things in general and have always found a solution.


Every Person would give you a different reason, though it will most likely be money, comfort or time or a mix of all of them.

I find 3ds Max to be great and very technical (complex) which means that you can pretty much create anything in it and there is a button for if you'll look for it. Some of the functionality is just amazing really. I like that even though the UI suffers for it. So the software isn't bad at all for me.

That said... if they'd keep perpetual licenses I'd own both but still probably use C4D more - I like the more organized approach and the development seems fairly constant. Its really fast and intuitive to create certain stuff - especially animation ala mograph. I do have criticism for the app and Maxon in general  too but nothing of the sorts like with Autodesk. AD is just weird.

So yeah, please keep developing the c4d version, lol :P

Hey guys, so I've been scouring the internet regarding this topic, replicating 3ds Max falloff shader in Corona C4D. However I got confused between fresnel and falloff shader in C4D. Can anyone tell me what's the correct workflow in C4D that closely replicate the effect from 3ds Max. Thanks in advance. Cheers !

So can anyone show me this feature is released in 2021? Or maybe it is not developed?
Thank you.

Please do not "Maxify" our c4d. There are tons of stuff out there only for max and only a few for c4d. We donnot want maxuser to hijack c4d!
