World Creator on displacement

[thanulee]

Hello. I got this issue from world creator and they told me to ask here as well, if there is any clamping operation behind the scenes when i import a texture for displacement.
I got heavy banding in 8bit (expected) but still minor banding in 32bit. Any thoughts? If u need image to check let me know to send u in a pm.
Thanks

Ensure everything is 16/32 bit in displacement pipeline.

It is, thats why im asking. World creator ppl tell me its fine on their side so i have to ask

So after few tests on other engines and talking with WC devs, problem seems to be octane (or me).
Here is a scene with wc project/32bit tiff/c4d project to give it a look.

Hi Thanulee,
In your image texture node, you have Channel Format set to half (16bit) instead of float (32bit). Update this, and you should get rid of the banding.

Heya, ya Iam set to float and i still see this issue. But im on 3.07. I dont know why on ur file doesnt appear to be float maybe its 3.07 to 3.08 difference?

[niestudio]

That's a different float. Yes I am on 3.08, not sure about 3.07

Looks like 32bit support in displacement is new in 3.08

Can you output 16bit from world creator or, I wonder if you can change your image to 16bit in photoshop and achieve acceptable results.

Thanks! Image is 32 bit no reason from WC, while with 16 i could achieve same results. Its 3.08 that i need to upgrade! thanks again
