Live Viewer Vs Render

[aoktar]

hi,
i had this strange issue too a couple of times. suddenly the final rendered image is much brighter and "washed out" as the preview in liveviewer.
my workaround is to copy the whole scene into a new projectfile. then there is no difference between the octane-liveviewer and the renderd picture in the picturemanager again.

not random, if you enable multipass, c4d output changes to linear color space. did you read manual for workaround?

hi ahmet,
no, i never changed anything in the scene: LWF and so on. no multipass enabled/disabled or stuff like that.
suddenly this issue appears.i have no idea what is the "trigger" for this strange "render behavior" of octane. but it seems that you can get rid of it by copying the whole scene into a new projectfile.

btw. i had this issue also if i change a lot between DL and pathtracing engine:
suddenly the live preview looks different: the pathtracing-preview is too bright and "washed out"

my workaround for this situation: just move the camera one unit in space (no matter in which direction) and again the brightness and overall look in the livepreview is ok.

i will test this again the next days with the last beta ( and with my brand new titancard on board ) and if this issue appears again i made a quick screen-cast for you.
btw. once again, Many thanks for your work Ahmet. octane/c4d is the real shit!i have so much fun with it!
cheers

Weird report, can you do a video capture to show this problem? I can check if you do it

Hi,
I'm encoutering another "Live Viewer Vs Render" problem.

Once again, everything is going well in the live viewer, but when I'm rendering, all my blackbody emitters are disapearing...

Any idea?

[aoktar]

sorry, but how can we have any idea with a image?

[tegatwork]

Sorry

I'm running RC1 on Win7, Cinema4D R14.

I've got sweep nurbs with Blackbody emitter for each neon, inside another sweep nurbs with a colored glass texture.

Same thing for the light bulb except that i'm using a sphere as emitter. Light bulbs are cloned along a spline with mograph.

Do you need more infos?

please send me this part of scene to let me check it. Also i'm curious about have you tried with some different options on a clean scene?

i had a similar problem with blackbody emissions. first frame of an animation showed no light at all (picture viewer) - the second frame seemed ok. i couldn´t trust the live-viewer on this.

[tegatwork]

Well well well...

After some tests i found that :

- my light bulb emitter were sphere primitives. As soon as I unchecked the "perfect sphere" option, the came back on the picture.

- In order to get a similar result of my liveview, i had to increase my blackbody emitter power from 10 to 80... The problem is that the liveview is now too much powerfull... but the render is near ok...

but it's still not very "normal", right?

[aoktar]

yes, Spheres which has Render Perfect option, cannot exported as other polygons.
Also took a look your scene, after some playing i can get exact same results.
Normalize option is enabled in BB_Emission. And played objects in cloner.
