yes this eliminates what the setup would be needed for! (to have no light but visible reflections from it)

[C4D] Daily Builds / Re: HDRI from Cosmos come as Plain White IMG
« on: 2023-02-17, 16:31:43 »
they are usually set so the exposure is right for real world intensity, like sun/sky etc, not for 8 bit preview.
so the "white"/defaulkt exposure, is actually correct and takes a way one extra step in raising the exposure so it fits the expected intesities in lighting.

"Not at all, prove it if I'm wrong."
->> well go to scatter tab (in volume grid), the setting "directionality" is exact the phase function you point to in the vray manual. the similar you have in volume material by the way.
edit: vray has also gi depth 100(see lightcache advanced) settings

we have similar problem here, hope this can be fixed.
sadly the occlude other light option is greyed out when emit light is turned off. when i turn on emit light and turn off occlude other lights it works ok, but this then adds light tot he scene which isnt wanted.
@beck what workaround did you find?

« on: 2023-02-16, 11:02:44 »
just checked as i also use this a lot. but here it isnt disabled, i am on latest beta(jan 23).
or maybe i not understand what you meant?

i can't talk about the speed, i havent yet compared with v-ray,
but the scatter phase feature you linked is also in Corona Render (forard/backard scatter value).

General CG Discussion / Re: Vantage and Corona
« on: 2023-02-15, 16:37:47 »
yes i think that woudl give Vantage also a nice boost, and growth of the userbase - as so many archviz companies are using Corona today on max and c4d.
so +1 from me

[C4D] Feature Requests / when object with tex copied into scene -> ask to copy them in tex folder(as c4d)
« on: 2023-02-14, 17:05:25 »
in c4d usually when one copies an object(with materials and textures applied) into a scene, c4d gives a message and asks if it shall gather the textures and place a copy inside the projects "tex" folder.
when using corona this sadly doesn't happen, and one has either manually collect and copy the textures, or make sure one has set a search texture path to this location(which is slow in c4d).
if would be great and an extreme time saver if also corona woudl have this c4d typical behaviour, and ask for copied in the textures automatically.
as far i remember this are only a very few lines added to the material, to trigger that feature from c4d.
i hope i was bale to explain it clear
thanks!

if you need a fast (real time) search and filtering system for the material manager, we actually have made this for us, available here for all here in hour shop 3dtools.info:

i need this all time in c4d:)
cheers

[C4D] General Discussion / Re: Any chances to improve render times with volumetrics material?
« on: 2023-01-17, 18:36:05 »
on a side note: As far i see from Maya/Houdini Chaosgroup announcements for V-Ray, V-Ray 5 added random walk some time ago in the new Subsurface scatter in in the new vray 5 material.
as vray 5/6 and corona 8/9 share a very similar material setup/features (mostly only different gui), i thought the new SSS also on Corona is random walk based?
i might be wrong of course, maybe the Corona team can answer that?
i also think random walk is nothing special fast if calculated precise. (maybe faster on gpu of course)
overall in RS p.e. some parts render fast for sure being gpu based, but other stuff and gui, like having just a few big 8k textures bring it here down to be very slow(2080ti), material previews are super slow, etc.
so i think which engine suits best very much depends what one needs, depending the type of work.
for me corona is still by far the winner for archviz at least.
what i woudl hope most is speed up of DOF, here vray is much faster yet with almost no speed hit, while in corona it seems to cost much extra time (while slower in other parts)

« on: 2023-01-15, 00:29:48 »
yes displacement, maybe even in c4d via the displacement modifier (using corona displacement for the fine sand grain).
for sand grain see to use/make a 8k texture or more

"When you propose coloured grains you mean i use actual geometry?"
no geometry, i mean a bitmap texture for color, and another bitmap for the ultra fine displacement
(dont use noise this tends not to work good with very fine details)
