[C4D] General Discussion / Viewport slow [solved]

« on: 2021-04-30, 09:25:35 »

Hi,

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)

[C4D] Bug Reporting / corona does not respect disabled nulls / lights with vray tag [BUG]

« on: 2020-07-09, 13:37:40 »

hi,

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

[C4D] Feature Requests / color brightness value

« on: 2020-07-08, 19:02:21 »

hi,

please consider to add the color brightness value to all color fields...
this is standard in cinema4d and it can often help to avoid shaders.

i for example get defined ncs colors by my clients.
for rendering i need to multiply them down a bit (white is max 70-80%)
ofc i can use hsv mode and reduce the brightness, but this changes all color values
and it gets difficult to compare back if i have the right colors.

the brightness slider (see standard c4d material) helps in many situations
it comes without cost and is a good thing to have!

[C4D] General Discussion / Sticky Releases Tread?

« on: 2019-03-23, 10:16:36 »

hi corona team,

finding things is a bit tricky here sometimes and i think it would be nice to have a releases thread in the forum.
for example: i could find the corona 3 hotfix 1 download outside of the forum, but the release notes... ?

it would also allow to add the beta builds and give a better overview what is around to play with.
best without discussion, just an archive of versions/downloads and their release notes.

just an idea,

I dont know if this was reported before,
but Coronas Memory warning pops up even if it is not used as renderer

[C4D] Bug Reporting / Corona Light Instance [Bugs]

« on: 2019-01-16, 19:36:30 »

In the Corona-3-c4d release from 01-2019

1) Instances of Corona Lights are ignoring the color
Corona Light, Instance, change Color in Light to red, Instance light will still render white.

2) Render Instances of Lights are working (including the correct color) in Interactive Rendering,
but they do not work at all (there is no Light) when rendering to the PV or VFB !

This has been reported here by illbru, and is tested by me, too.

hi,

i stumbled on this interesting video:

https://sobotka.github.io/filmic-blender/

wonder if this does apply in any way to corona too...
anyone with thoughts on this?

[C4D] Feature Requests / corona shared problem

« on: 2018-09-09, 20:51:47 »

hi,

this is not a bug but a gui problem in my view...

if you work in the normal mat editor
and you instance a shader by using a corona shared shader in another slot
then the original shader also gets a corona shared as parent shader

i understand the concept that there is no source and target,
but both slots now share the same source

the problem is that
1. you cant select and copy/paste the original shader anymore (to copy it to another place without instancing it)
2. you cant unlink the connection if you dont want it anymore

at least there should be an unlink button which removes the corona shared shader
and puts the original shader back in the slot.

how to handle the copy/paste problem i'm not sure

[C4D] Resolved Bugs / Multipass Mask / Cloner [bug]

« on: 2018-05-31, 08:13:49 »

Hi,

Yesterday i noticed that adding a group with a cloner to a mask
does not work. The clones are not added, also if recursive is on.

The only way right now seems to be make the cloner editable
(dissolve it into instances)

i didn't check cloners with other multipass features,
but i guess this doesn't affect masks only...

would be nice if that was fixed

[C4D] Resolved Bugs / lut folder mac/pc troubles [bug]

« on: 2018-05-14, 15:25:30 »

hi,

that was reported before but i repost it anyway...

i just received false renderings from rebus farm,
because when rendering a mac file on windows (and vice versa) the default lut folder is not changed
and results in a wrong path/missing lut on the other system.

corona should detect and adapt the default folder to the os automatically
or have a fall back to always search in the default paths if a lut cant be found...

[C4D] Resolved Bugs / opengl issues [bug]

« on: 2018-05-08, 11:34:24 »

this might have been posted already...

on macosx sierra sometimes materials are not displayed correctly in the viewport
(ie displayed in a bright green instead of rendered with texture)

re-rendering the material does not update the display

the only way to get a correct display is to close and reopen the file.
which also does not work in all cases, sometimes you must try a few times

[C4D] General Discussion / colormapping 16bit (antialiasing / brightness range)

« on: 2018-05-08, 09:04:30 »

hi there...

in vray i use reinhard colormapping and i save my pix as 16bit images to have some space for post edits
now in corona i noticed that my lights are totally burnt in, darkening in post does not allow
to reduce the white halo of a lights surrounding for example, while this works perfectly in vray.

in corony the lights generally seem to be much brighter in the output due to the missing colormapping.
this results in much stronger antialiasing artefacts and also limits post editing a lot...

how do you guys cope with that?

[C4D] Resolved Bugs / Corona Sun ignores Renderbit (bug)

« on: 2018-04-27, 15:14:32 »

in B1 you can turn off a sun only by the generator switch (green checkmark switch) !

a corona sund does ignore its own and the parents renderbit
and so cannot be disabled by setting the renderbit of a parent to red (disabled)
