Redshift supports OpenColorIO 2.0.1 / ACES

[C4D] General Discussion / Re: Switch from Arnold to Corona?
« on: 2021-05-24, 14:29:48 »
well, i tested arnold a bit the last 2 weeks and i had loads! of crashes, even with simplest scenes.
some stuff in arnold is weird and super user unfriendly. on the newest arnold i wasnt able to have a glass window letting light pass. needs a comptag.
on the other hand corona is the only renderer who thinks it is not important to have a manual.  forum support could be better, too
what kills arnold for me is that interiors are rendering way too slow. not sure if i'm doing something wrong, but my guess is 3-4x the rendertime of corona or vray
another bummer is that arnold doesnt use real world values for lights/cameras. you have to "feel" it
i gave up on arnold with the feeling that in parts it is years ahead and in parts years behind.

ok, i did some tests... and then even more tests....

sorry, this is probably scene and not corona related !

this is not a slow system... its a 3970x + 128gb + nvme
also these slow viewport changes do not happen with other renderers
the scene is not particularly large.. it is 350mb
maybe this is caused by scripting tags, i'll do a test on this later today.

i'm no expert here and I didnt even watch these videos now.
i just saw how ACES works on arnold and i assume they know what they're doing.

there you need to "import" textures (means correctly set them up in the bitmap shader)
normally as sRGB Texture, HDRIs as Linear of course, this is the same if you use the LWF.
the difference is that the result must get exported from ACEScg after rendering
on arnold you must use their VFB, you cant see the proper result in PV directly

after the export to sRGB the images look very natural out of the box
with LWF you need to post process on a guessing base to get yr final image
for me it looks like ACES gives you better pictures with less work

EDIT: Arnold has it, it is planned for Vray5 on C4D,
it would be nice to get an update from Corona what they think about it

hmm... I dare to say it... none of the available M1 macs is suited for rendering. O:-)

years later CXR saving in picture viewer is still on the trello board...

i just want to mention that arnold uses "drivers" for such cases
their drivers are objects in the object manager where you can adjust settings
on finished render they trigger a save in the desired format.
even filename tokens are supported.

this is used for a deep exr with the needed AOVs for denoising for example.

maybe you could have a look at it
(as i remember you didn't find a technical solution)

after having seen ACES in arnold i'm bumping this topic.... !

ACES support should be added to every renderer just for the dynamics, only! :)
makes it way easier to deal with lights and over saturation

would it be possible to reconsider adding this to the roadmap?

So the conclusion is?
Shared Shaders do not work on Rebus ?

This would be most annoying
(making them useless for me)

[C4D] General Discussion / Viewport slow [solved]
« on: 2021-04-30, 09:25:35 »

Is there anything known regarding Viewport slowdowns ?

When I switch from 4 Views to a single view and back, I can't see anything for serveral seconds.
(Such slowdowns do not happen with other renderers)

Windows 10 / R21 / Corona 6 (stable)

best, index

as i experience crashes too, sometimes
just when rendering locally, no TR involved...

can i ask about the shader policy?

i often use c4d-layer shader setups
and instance them with the corona instance shader

is it safe/allowed/intended to mix c4d and corona shaders?

tx jan, but i guess i'm not the only one experiencing this.
while vrayforc4d never crashes, corona 5 sadly did quite often on windows 10 / R21
maybe i give it a try again with the new version

corona is really developing fast lately...
i just wish it would be more stable, it crashes from time to time and that makes me hesitate to fully switch over...


i just found out, that corona is lighting my scene with a (vray) dome light that was in a disabled null (both dots on red)
took me hours to figure out the strange lightning and never thought it would come from this...

null (disabled)
- null (disabled)
  - dome light (enabled)

--> this should not light the scene
--> it seems to happen when the dome light has a vray light tag, without everything is correct

i know, i shouldnt have vray tags in the scene,
but i'm converting, so that can happen

best, index
