thanks Paul!

Try upping your isoparms via rebuilding the Rhino surface.

Hi Paul,


I get all the faces offset/exploded at the edges inside rhino, wich basicaly makes any displacement very difficult to use..

Any solution/workaround?

Did you adjust the shift value? This should help you out along your edges.

No shift value, left at default of 0


Shift value adjusted:

Rayepsilon to 0 don't work..the map is a black and white png...

Can you try Bendbox's suggestion pls. If you have no luck, pls send me the scene and I will take a closer look.

Area D, I have had a good look through your scene.

1) If you have a 6000x6000 displacement map, I think using the maximum "Level of Details" will retain the high resolution.

2) The displacement is 8bit. IMO you need 16 bit jpg/png for displacement maps

3) There is an issue with the way Octane is handling the displacement of your scene, and I will forward this to Otoy. However the easy solution is to either a) increase the displacement "Height" or b) increases the number of polygons in the floor surface. I believe the problem arises because it is not possible to set a high enough ray epsilon for the size of that polygon (being the floor) and the small amount of displacement being applied.

I hope that answer your question.

Hi Paul,

i've tried your suggestions,the best is to increase the number of polygons..but in complex scene the weight of file is not sustainable.
Displacement map 16 bit does not improve the situation. However the problem persist when the height value is too low..
Thankyou for the support

You only need to increase the number of polys for the floor surface, which should be a tiny increase is the total scene polygons. There are only 2 polygons for your floor - which is not enough.

I have refreshed the installers at the top of this thread with:

2.1.0.9
- Compiled against Octane 2.01
- Resolved issue where meshes with Octane materials assigned could not be UV unwrapped and edited. This is a partial fix, and the complete fix requires the next Rhino service release (SR10)
- Reformatted some panels so there display correctly when Windows has the font set to 125%
