wrong glass material between c4d and standalone

[jayroth2020]

Hi Salmon, I suspected something like that. Let's start by removing the scattering node and see if you like the result. Glass is pretty simple overall: use an Octane Specular node, add a very tiny bit of roughness for clear glass (0.001 for example) and set your IOR to 1.52 (which is crown glass). Enable Fake Shadows for architectural glass. I often add a little green tint in the Transmission channel for realism.

i've tried the "architectural glass" from Live DB and the problem still remains. You can see that in the Studio Standalone

I’ve put my workstation to render. I’m trying to get to the delivery in 12 hours. I can’t run any more tests now. it doesn’t occur to me that other things test. if you manage to locate the problem I cancel the render and upload it to the RNDR

Jay, i'm doing well working on meters in cinema 4d and octane?
As you see there are no hidden objetcs because everything was imported from archicad, where i work in meters.

Also don't use this camera setup without baking to keyframes. It's like moving randomly.
I found this mesh is bugging it, looks like faces are with bad ordering. Probably you need to fix this mesh

[aoktar]

Apply this triangulation to the model that's solving the face misordering.

I have used the plugin DIN 3D to export the geometry from archicad to cinema 4d.
I never had problems to render in c4d but it seems i will have in octane studio standalone.
So i will check the export method from archicad.
Thanks Ahmet. Its not easy to find this kind of failure. I will go deep into this.

I disabled the fachadas Vidrio-Claro object, which is the glass, yet I still see these other shapes when I export to Standalone. That indicates there is another object in that same section, which has the material Pintura 21 or Pintura 22 applied. Upon further investigation, I suspect it is one of the objects in Pintura 21 causing the issue. Looking at the meshes in the objects with that material applied, the tesselation of those objects is not ideal. Likely fachadas Pintura-21. I would not be surprised to see an errant point in that object. Usually issues like these are geometry-related.

I have confirmed this by disabling that object and exporting to Standalone again. Bad geometry, which you will need to address. The Mesh Check command in Cinema is helpful for cleaning up these issues. Fortunately, this is a very simple shape, and you should be able to resolve the bad geometry rather quickly.

Thanks Jay, appreciate that.
I have to try another way to export geometry from archicad. This plugin its not good for Studio Standalone and in the future i will use it a lot with RNDR.
MANY MANY THANKS

You're welcome. Most CAD systems create data that can give render engines trouble, it's just part of the game.
