[C4D] Feature Requests / sky with clouds (like in vray 6)
« on: 2022-06-16, 00:30:18 »
as vray5 did get the nice new corona sky,
i hope corona 9 gets the great new cloud feature from vray? :)


as title says, i hope will be like scatter a tool for both engines:)

maybe it can make it into corona 9 ? :)

here i made a small setup for this:

just place the hdri you want in the corona sky object,
it will auto load the same in the c4d sky object and show it in the editor, hope this helps:)


love cosmos,
BUT: as the new physical mat has always a white reflection and no way to dimm it, many cosmos objects have way too reflective materials.
they come in with ior 1.6 or even 2 for many trees p.e.

- so please either bring back a way to reduce reflection manually,
- OR psl add a way that the cosmos libraries translate better with the new corona material, meaning very low ior values:)



for some reason here, when i use chaos scatter in my scene, in IR every camera move initiated a full scene parsing.
i guess/ hope this is a bug.

can you check that, as the scene and scatter not changes in relation to camera i think it should not need a new parsing of the scene, that makes IR not interactive any more. As soon i hide the scatter objects, IR is interactive gain without re- parsing the scene.

Or do i oversee something?

thanks for help!

Dear Corona team,

first a BIG thank you for the very nice v8 version! :)

i have one big feature wish though which might be very easy to add:
when i copy paste a c4d material from one c4d scene to another, c4d asks me if i want o copy the assigned bitmaps into the new scenes "tex" folder.
this is VERY useful when working with assets, or copying parts from one scene to a new one.

sadly with the corona materials this feature isnt activated. as far i remember it is a simple line of code to add to the material, so that c4d activates this feature from the hostapp.
(maxon sdk supports for sure can tell that)

if any possible please add this small but very helpful feature to one of the service packs, people will love you for that ;)

i found a Bug with the new tone mapping and connecition to cameras.

here and there when using IPR and switching between default cam and saved scene cameras, the tone mapping in the saved scene camera gets lost.

so the default obviously has a default tone mapping, my scene cameras special tone mapping used. when i switch to default cam and back to scene cam, the scene cam here and there has also only the default settings.

i hope it is understandable what i mean?

i had this happen in several scenes, but it only happens here and there, not regularly.

Hi All,

can it be the convert scene function doesnt work for vray 5? only for old vray 3.x?
or do i oversee something?

thx for help

[C4D] General Discussion / new lic questions
« on: 2022-04-13, 20:42:33 »
before i really use the new v8 with all machines in productions, some clarification on the new lic server use would be fine:

1) i am worried what happens if internet has an temporal outage;
how long can the office be without internet before corona will stop working (in case of internet issues), V-ray had been very strict  in that regard in past, hope that is improved with new chaos license server versions, like it needs only every 12h or 24h  a connection to the  internet or the like, before it all stops working.

2) or do i need to use the "borrow lic system from chaos to ensure 1)? i hope not, so that the regular system allows some downtime of the internet in default setup?

thanks for infos!

[C4D] Daily Builds / some small rc4 encounters
« on: 2022-04-12, 13:13:45 »
Dear Corona team,

overall the RC4 runs pretty smooth, i really love now the new tone mapping pipeline, thanks for that:)

2 smaller things happened in rc today, maybe some others had that too, so i report it to make sure:

1) i had a case where i made a new camera (so it a copy of the previous active one) and moved it, then i wanted to switch back to another and then back to the original camera, and it lost parts (newly added before to that cam) of the tone mapping settings. i had added an aces, and tone curve i think, which had been suddenly missing, and it also had then a false exposure.
i am not sure what happened but i had to go back to previous saved version to get the exact tone mapping back

2) the corona vfb vanished once for me, the only way to get it back was to restart c4d r 25.

so far both happened only once, and i wasn't able to reproduce yet.


as title says, is this possible?

i sadly get weird artefacts if 2 or more intersect


first congrats on  the new tone mapping, i test yet to try to get the same output as before.

one thing i see that isnt right when i open my old scenes, is that the curve setting is ignored and not added to the new tone mapping system.
we heavily use custom curves in our process and need those also in new v8 beta when opening our scenes

i hope it is easy to fix that/adding the old curve paramater to the new system.

i hope this is the major source for the different look so far, will continue to test:)

edit: on more tries this time it did also "forget" the lut setting", so seems randomly it yet misses some settings in new file when opening old scenes with more than one camera and different settings per camera


before testing the new beta 8 with chaos lic, i need to make sure all works, and to understand the process of the license system:

i have  several vray lic under a chaos account that exists since long.
and i have corona licenses under a corona acount.

how can i use all on one chaos lic server, or do i need to run 2 different chaos servers with 2 login accounts?

i need both engines active at the same time on my machines

thanks for info!

[C4D] Bug Reporting / R25 scene crash
« on: 2022-02-14, 20:14:52 »

i have a bigger scene which crashes on one machine in r25, but not in r23 with same corona ( both latest beta 8 from feb 2 2022)
a slightly older version renders fine(before i added some assets)
it also renders ok on corona 6 and r23 on same machine

it also doesn't crash on my other machine with same corona 8 beta  r25,

all pcs have the same OS, same ram and same extentions (corona and same vray verison installed)
no bitmaps are missing

i tried with de-installing vray on that machine(in case there was some leftover ion the assets)
when i open the scene then it doesnt find a vray shader (so there seems some hidden mat or shader, but this should not crash and doesnt crash on the other machine)

i disables "render 3rd party materials" in render settings
ram is plenty (59% usage only in total)

can i send you the bug report to check that that is, i am out of ideas?

[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 ?
