Displacement -> baking texture node causes displacement to disappear on update

[leave2]

Hi there

I'm having a problem I can't seem to fix. I'm trying to map a displacement onto a mesh, and I don't want the displacement to repeat or tile, so I'm piping it into a baking texture node. Doing so displays the displacement, however, the moment I make a single change to the baking node in order to dial in the displacement, it disappears, and won't reappear unless I delete the baking node and pipe in a new one

Hi, did you try Boder Mode in Texture Node?

Hi,
if you switch from Texture to Vertex Displacement, the Baking Texture node is not necessary, and you can do whatever you want with Border mode:

Hi Bepe,

Problem with that is the displacement then adds 3 million polys to the mesh, which was previously only 200k. Increasing the poly count of my mesh by 10x because of a software bug seems excessive, no? Or am I missing something about Vertext displacement that prevents such huge increases in poly count?

I've only been using Octane a couple of years, so there's tons I don't know

Thanks mate

Hi,
Current Texture displacement is Voxel based and has several limitations at the moment.
It will be enhanced in upcoming 2026.1 version.
To avoid the limitations, the best option is to use Vertex Displacement, since OctaneRender doesn't have issues with high poly meshes, especially because Vertex Displacement supports RTX acceleration.

My two cents.

ciao,
Beppe
