Blender>Speckle Viewer - Meshing of Lugplate

Hello guys,

we have imported a Step file with Stepper into Blender and pushed that to Speckle.
The mesh in Blender

The shading in Blender

The view of the Speckle Web interface

The viewer displays it a bit differently. It is more an aspect of optics and nothing mission-critical. Still wanted you guys to know …

Out of the IFC it looks better:

Here ist he link to Speckle

and here is the file
lugplates.blend (1.4 MB)


It is basically every scenario with tiny boreholes

Yep. Unfortuantly this is a bit of a known “gotcha” with our current state of Blender connector.

We don’t currently support sending vertex normal data, thus, the viewer and receiving connector re-calculate the normal data on receive. This is fine for some geometry. But its common for geometry imported into blender from elsewhere to have custom normal data that we don’t currently capture. Thus the shading looks weird.

We do have a ticket to implement sending/receiving normal data through Speckle, but still needs some investigation on our end on the best way for us to support it.

In the mean time. You may find some success by adding an Edge Split Modifier to your geometry before sending to Speckle. This changes the vertex structure a little, but often leads to geometry that renders better when sent through Speckle.

Not an ideal solution, so I’ll keep you posted if we get around to implementing sending vertex normal. Unfortunately I don’t have a timeline just yet for this.


Thanks for the explanation :slight_smile: . It is not super mission-critical to us and the list of you guys is long. For now, we are taking the alternative route of using Step > Tekla > Speckle.

Thanks and all the best,
