PK,

in this case you could potentially add a simple mid-grey image into the displacement channel of the "soil" material and give it a 1mm displacement value so that it would get pushed/pulled away from the intersecting face of the glass volumes you've used to do your boolean operations? You'll ...

Hi Paul. I think having exactly matching vertices would be a special (and rare) case, but having co-planar (or even near co-planar) polygons more generally that results in problems is not so uncommon.

I recall seeing flickering in 3D games when this used to occur through some error of modelling ...

You can try reducing the Ray Epsilon to the lowest value possible (but that might cause artifacts in other parts of the scene). Unfortunately you need to avoid having vertices with the same position which belong to 2 different objects, otherwise you will get these artifacts.

Thanks Paul.
I ...

Note, a workaround (not at all ideal) in ArchiCAD , when the glass mesh is a CADimage site planning envelope, is to review the boolean operations on the glass mesh, and delete the one where the main ground mesh is subtracted from glass mesh. This removes the coincident polygons issue in Octane, but ...

I have one semi-transparent (glass) mesh that is boolean substracted from a lower terrain mesh
This means that the base of glass mesh object exactly fits the top of terrain mesh object , so there are two coincident polygons, with different materials defining the junction of the two.

How do I ...

I have updated the TEST installer for AC22 at the top of this thread with:

4.01.1.89
- Fixed "Removed the Cuda Devices list, and replaced with the Octane Standalone Devices panel" which was missing from the previous release
- Fixed issues associated with 4k monitors
- Potential fix to the ...

Can you send me a scene where this happens please?

Thanks

Paul

I have unfortunately since worked on the file to the point all textures have been manually replaced with Octane textures, and cannot now seem to recreate the issue. either with current file, or from scratch.

I am wondering if the ...

Another possible bug: Even when ArchiCAD is loading all objects and textures from an uncompressed folder (i.e. not an .lcf and not embedded), most textures are not coming through.
Cuda log reports no errors, and selecting the texture and using the 'Reconvert From ArchiCAD material' function does ...

I have been a long time out of the loop with Octane, but having upgraded to this version (4.01.1.88) am noting that the material selection using eyedropper in viewport is not working properly at all. Over most of viewport image, no material can be selected at all, and where I can get a response, the ...

ArchPrime , I don't know if we are talking about the same thing but I do walkthrough in octane plugin. Be sure that viewport window is not in the middle - drag it in one edge or use a second monitor. ASDW works fine...
Thanks nick73

Yes that has always been available, but I am not seeing any ...
