Title: Incorrect Gamma Values Cosmos Assets?
Post by: tuami on 2022-12-21, 16:04:17

Hello i have problems with comos assets that the colors are displayed garbled (too dark) and it only affects objects that are loaded from cosmos.

I have to convert the assets to polygons (then add pongtag otherwise the mesh will be messy) and then change the color profile to manual gamma.
A value between 1.3-1.6 makes the object look more natural in brightness.

I would like to use the assets "on the fly", so I would like to know if this is known and adapted in the future?


Cheers

Hi tuami,
Thanks for reporting this.
Could you please provide a scene file (or the affected part of it) so we can investigate further?
You can use the uploader on my signature.
Additionally, have you spotted some additional assets like this one?
Looking forward to hearing from you.
Kind regards.

Hello Benjamin,

I have just uploaded the scene via the uploader. Also a Screenshot attached here. Very dark material.. We actually have this problem with all 3d people. The materials are also very basic, just a diffuse map and no reflections properties and bump/normal maps set.

When importing the assets they appear as such:

When changing the gamma manually to 1.3, I got the following. I feel this looks more un-natural, especially for this with a darker complexation:
