[C4D] Daily Builds / Re: New Cosmos browser

« on: 2022-02-04, 11:57:02 »

i think i found a small bug yet:
some cosmos objects import with empty material tags, i think this happens when a material is applied more than one time in original cosmos file.

you see this for example on the tree called "Rowan 002".
when i import it via v-ray it has 5 material tags with 3 unique materials applied tot he 5 tags.
in corona it has also 5 material tags but 2 of these material tags are empty(showing a "?"), - i assume the ones that needed one material applied 2x tot he object:

"Would it be possible to store the downloaded objects under their name "

+1 just wanted to ask same:)

thanks i read that yes,
but it seems no triplaner involved, like the material from a tree created is 100% transparent in materialsphere,  or the trunk shows plain brown, even thogh there is a bitmap in diffuse etc (also no triplanar), etc

[C4D] Daily Builds / New Cosmos browser

« on: 2022-02-03, 14:29:38 »

Dear Corona team,

LOVE the new Cosmos addition in the v8 daily - thanks for that!

a few questions i have:

- i cannot see correct material previews, the textures not show in the previews of the material sphere, they render correct though then in ipr and final render, so i have some wrong there or is this yet an known issue?

- atm it uses the web browser, this seem to conflict with the use in a dropbox folder, probably due the web browser use? (in vray with integrated cosmos browser it works) i can only import downloaded files when i pause the dropbox. i guess cosmos will also get an integrated cosmos window, right?

- some materials are very reflective or shiny in comparence to the cosmos originals. the same in vray seem yet at least to me a bit more realistic (like wood floors p.e), i compared for example this "Wood_Tiles_Shiny_04_200cm". do we need to lower the IOR ?

thanks!
Stefan

the name "legacy" usually implies that it is planned to be be removed sooner or later.
i also fear the old might not be compatible with the future interchangeability with other Chaos products,
so we might not be able to use the legacy mat with chaos cloud and other future products that might come

anyway i give up here, i said what my believe/need on this subjects is, from 3d artist/user perspective.


i guess time will show if i am the only one needing to control the reflections in this "artistic" way, or if more users might want this:)
until now i have seen Coronas main policy to be very user and artist friendly, i hope this stays so.

"why not? legacy mtl is not going anywhere. another option I see is asking devs for additive blend mtl.<"

how you know that? are you official from the corona team or have official infos?
will it work on the chaos cloud, or in vantage/enscape connections etc in future?
how does it go with vray 5 materials (and possible later exchange  back and forth to vray/or overall in CHAOS eco system (vray 5 has kept the full reflection controls)?

i really think it is not correct to take away this controls of a modern material. it should be a tool for artists.
the new material isnt fully physical anyway, as colors you can use, and other % controls etc are there, which arent physical at all (the whole "PBR" thing isnt fully physical at all, which is ok).

overall "jojorender" brought it good to the point

guys really,

beside all other, - how you imagine we cope with very very usual requests from customers:  "please make glass reflection lot less" ?

can someone explain me, what i shall tell the customers? "No i cant, - it is not physical"? ;)
(and yes we all should use the new material not the old legacy of course)

"It's basically what the new Physical material does with roughness, isn't it?"

yes it does in v8 exact that:)

[C4D] Corona Goodies - User Contributions / Material filter/search for C4D Material manager

« on: 2022-02-01, 21:06:26 »

Dear all,

do you also hate it to search through endless long lists of materials in the C4D material manager?

for exact that we created a new simple yet power4ful helper tool, the material filter plugin, you can find it here in our shop 3dtools.info:

https://3dtools.info/shop/matfilter/

it simplifies the task greatly
you can filter by name or pats of the name,  it updates the search results in real time while you type.
you can dock it anyway in your GUI

hope some of you like it and find it useful:)
cheers
Stefan

"With PBR technique it's advised to take photographer's approach to lighting & shading, look dev."

well a photographer taking a shot of such a reflection reduced glas will get the right result,
exact that option i wish for the new corona mat, to recreate reality;)

thanks a lot,

as said the scene uses many instances(mograph cloners) most of them in multi instance mode,
i think also some hair generators are in the scene

i dont think so to be honest.
these materials do exist in real world, and are pretty often used.
a physical material that cannot do often used real world mats isnt yet really physical, for my understanding at least.

and second we are still artists and need to react to our customers wishes.
Corona is a tool for artists as far i understand it, and its target is to provide us a good and easy to use work flow.
the future of the phy-material will be only bright if it let us make the usual daily needed material tunings

this is what i mean, it is available in almost any other material feature already, so adding it would be consist i think:

i am trying to use glass, as it is used in architecture, to suit our usual customers, so in a normal way, and glass is said to be much more realistic in new physical material overall.

i would love to eliminate the old legacy material use for most things, and i do think the new phy-material is the way to go for future, but also believe this one feature (reduce reflections) is needed to really create all usual real world materials with it.
glass is one of the #1 used materials in archviz, and atm is hard to use as it cant be tuned the needed way.

 i truly believe this would make it not less physical, as we have these controls in almost
very other material feature already now.

thx, but we do not talk on high light compression or tone mapping;)

it is about simple be able to control (reduce) the reflection,
in special for refractive materials (other than lowering the IOR non-physically)

"IME, lower IOR is defined, "

that does sadly NOT work, as the ior then would be needed to be like 1.07 in my scene case, which doesnt look like glass in its refraction anymore
.i tested that already.

the indigo render cases seem not to have any solution and seem also not covering the low reflective glasses that archiz very often  needs.
it is not only a but the one specific glass but there are many variants. also customers often demand " make the glass a  lot less reflective", where we  as renderer should to be able to suit their wishes.

we need a way to recreate this reflection reduced materials (that are real wordl materials, they still do have a refraction IOR of 1.5-1-6)

i think in reality the glass producers do this with some special coatings, but the corona coating not let me do this complex effects(reduce reflection but keep glass super transparent)

we DO have currently have a value % in the phymat to "dimming effects" already for:
1) base diffuse
2) refraction
3) volume
4) clear coat
5) translucency
6) thin absorbtion

ONLY not for normal reflection, i really ask myself WHY this single  one is missing?
the other % values arent more physical or less than they would be for reflection to all my understanding.
as it would only reduce reflections, the danger of making too bright unrealistic materials isnt the case in such a setting.

this is for every days use a very important thing to keep us artistic control and to mimic some important real world materials, as explained-
for refractive materials lowering IOR is not an option to achiev that wanted effect.

i do love the new material , beside this single missing control, which i truly believe is very important
