Hi @Ryan,

Not sure if it is a Bonsai or Blender issue, not enough expertise to check that, but opening the House.ifc of https://hub.openingdesign.com/OpeningDesign/Bonsai_Tutorials/src/branch/main/069000_20250226_1738%20-%20Adding%20strip%20footings step on Linux (Ubuntu 24.04) with different Blender release with "Viewport Shading: Materiel Preview' enabled:

  • Blender 4.5.4 LTS with Bonsai 0.8.4:

blender 4.5.3

with "GPUTexture: Blender Texture Not Loaded!" message in console.

  • Blender 5.0.1 with Bonsai 0.8.4, also tested with bonsai 0.8.5-alpha260130:

same as previous screenshot, upper slab in pink,
with "gpu.texture | ERROR Failed to create GPU texture from Blender image" message in console.

In addition, if I attempt to open this ifc file by drag and dropping it to blender, this last crash (segfault).

Same with Blender 5.1.0 Alpha with bonsai 0.8.5-alpha260130.

While according to video I should see:

expected from video

this seems related to Materials/Materials.blend file, indeed oS_Wood_OSB.

Regards.

Thanks @esteban.dugueperoux for sharing.
I wasn't able to replicate this, however.

Try the 'update current style' button in video...

If that doesn't work, try...

os_version: 10.0.19045
python_version: 3.11.13
architecture: ('64bit', 'WindowsPE')
machine: AMD64
processor: Intel64 Family 6 Model 158 Stepping 10, GenuineIntel

Hi,

Thanks, the second option works.

Otherwise https://hub.openingdesign.com/OpeningDesign/Bonsai_Tutorials/src/branch/main/081000_20250307_1247%20-%20Walls%20now%20show%20their%20layers README seems to contains a broken link.

Regards.
