OTOY Forums

Hi Paride, thanks for the further testing.
Seems ok BUT - as said - the projection of the map is very small, which usually solves (making the issue so small you cannot see it).

Can you make a last try ?
Get your second picture above - the one with the box near the beach - and just change the projection size of the displacement texture to, say, 10x or 20x that size.
So if now it's 100m x 100m, make it 2km x 2km, and raise displacement height accordingly.

Let's see if something happens

thanks
Paolo

Hello,
If we’re looking to confirm whether the system will show issues with the geometry, we can safely say that it likely will. This is probably due to (though I could be wrong) the limitations of the texture displacement node’s resolution settings and the amount of RAM available (some crashes). In video productions, it's not common to use a single geometry for all scenes. Instead, different geometries are utilized to optimize resources by adjusting the level of detail based on the specific needs of each scene. We’re dealing with a 50 km scene, aiming to use a massive displacement map and then zoom in on very small details ( Additionally, using texture baking as a workaround for procedural textures (since vertex displacement, which comes after texture displacement, doesn’t require it) significantly hampers the real-time rendering workflow, which is central to Octane Render’s philosophy. The texture displacement node has its limitations, and as far as I know, developers are working on a new version. Furthermore, this workflow won’t be feasible because the baking texture node doesn’t process textures seamlessly. A more practical approach would be to bake the textures needed for animating the waves and then apply them to animate the displacement. I hope this helps.

Hi Paride,

thank you for answering. Beside any possibility we have, i assure that current displacement has major limitations in comparison with any other engine, so it's a relief that Otoy is working on something new.
Independently by the technical choice, you will hit a wall easily in a direction or another, and hopefully new displacement will solve.

Best
