Title: Clamped viewport when using OCIO
Post by: John_Do on 2025-03-25, 11:05:06

Hi,

I'm experimenting with OCIO in C4D and the VFB(2) doesn't show the correct result, like it's clamped.
To be clear it is clamped since I'm using the default view transform of C4D, but in a weird way, like a veil on top of the image that makes it dimmer :

EDIT : Even with the Raw view transform the image is clamped :

BTW the VFB doesn't show the view transform but I guess it's expected since it's managed by Cinema ?

Also I noticed that the raw values picked in the VFB are always clamped to 1,47, is there a particular reason for this ?

I can confirm this. Surely this can't be the first report of it?

I tested when this feature was first introduced and got crash-fested. Also mentioned it on Discord, but never checked it again.
