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

Feature requests Cinema 4D / color brightness value
« on: 2020-07-08, 19:02:21 »

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!

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,

would it not be possible to add something like "save to CXR" to the (corona) render settings,
and then use the settings in the normal save dialog? (including support for filename tokens)

this way you'd get the normal jpg/png/exr plus the cxr.
if checked, the cxr saving would take place even if save is disabled in the render settings.
like this you could save the cxr only.

not really the most elegant solution, but a workaround most could live with, i guess.
(if it is not possible to add cxr as normal saveable format)

I dont know if this was reported before,
but Coronas Memory warning pops up even if it is not used as renderer
(ie when rendering with VrayforC4D)

Thanks for that, much appreciated :)
easy, i tried to create a help desk ticket first,
but it seems that needs a separate registration / login ...

Bug Reporting Cinema 4D / 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.

by the way,
my browser always exits the thread after i post something...
is this normal? wanted?

i tested that :
macos 10.12, cinema r19
normal instances do ignore the light color, this is certainly a bug
render instances do not produce a light here at all


in this video it looks certainly way better...
is there something wrong in the setup?

i scaled all down, 20x20x20 cubes, with rounding 0.5, 1, 2cm
looks a bit better, but nowhere like in the video

for me it looks a bit like something is broken with the roundshader.

i also hoped this would make it into the release...
perfection would be if renderfarms like rebus would be able to deliver cxr files

just wanted to report that the officially released v3 crashed here after 5min playing with the node editor/materials
just made 2 materials and connected some dots (shared shaders)
macos 10.12 sierra, cinema4d r19

did you guys experience crashes, too?
