Oh, I meant 8k sorry. You still get the artefacts with a 16 bit texture? What you're describing sounds like what you usually get when trying to do displacement with a 8 bit texture.Lewis wrote:In that demo sample i downloaded there is only 8k 16bit PNG, there is no 16k texture ?Obizzz wrote:Lewis: use the 16k texture. It's 16 bit and doesn't suffer from this.

Hi Obizzz,
I also had this problem randomly when using 8k png.
This is why I changed the 8k's to tif-format.
Open the png in PS and save a tif.
I tested the map here - it has 16bit and it should work correctly.
Cheers

Ah, sounds like a bug in Octane where it sometimes reads a 16 bit png as 8 bit then.Subroutine49690 wrote:Hi Obizzz,

How did you mix displacement textures when you can only use one in one material ?

Use the Mix Material node to mix two materials with different displacement textures?BorisGoreta wrote:How did you mix displacement textures when you can only use one in one material ?
Wouldn't that make "mix" 50/50% of both materials so neither of textures would show fully (100%)?Obizzz wrote:Use the Mix Material node to mix two materials with different displacement textures?BorisGoreta wrote:How did you mix displacement textures when you can only use one in one material ?

I thought you can't mix displacement maps, that is why material mixer has it's own displacement input which you need to use to have any displacement at all when mixing materials.

Lewis: you can use a mask to control the mix but in this case it sounds like it might not work anyway.
