3 years ago The closest I could find so far which isn't too bad actually:
- Slice without support or brim and prefer a layer height of 0.4 (for standard prints).
- Create a metaball (Shift + A > Metaballs > Ellipse) with:
- Radius: 0.015
- Size Z: 0.5
- Resolution Viewport: 0.01
- Render Resolution: 0.005
- Influence Threshold: 0.001
- Import with Split into layers deselected and Subdivide selected.
- Select the imported mesh, Particle system:
- Emission > Number: 1000000 (or more)
- Emission > Frame End: 1
- Emission > Random Order: Unchecked
- Emission > Source > Emit From: Verts
- Physics > Physics Type: None
- Render > Render As: Object
- Render > Scale: 1
- Render > Object > Instance Object: Mball
As for a material that makes it looks like transparent (using Cycles and a HDRi environment set up with a shadow/light catcher):
- Principal BSDF:
- Roughness: 0
- Transmission: 1
- Transmission Roughness: 0.2
- Alpha: 0.4
Result:
First I'd suggest to add to the README how to install (being a noob in Blender):
Second I'd suggest to add in the README an explanation for both options:
Third I'd link to the WiKi which is really useful to get something to start rendering. I don't yet understand why the initial imported thing does not render or what it is exactly.
To give some background, I'd like to preview transparent filament, so I need to get the infill to render. However using the Convert To and setting Depth generates interlocking meshes which do no seem to render properly when translucent. I guess the meshes must be merged a bit like they get fused in real life. For that I tried the Weld modifier with a value of roughly half of the curve's Depth. It seem to do half of the job but only half and it's extremely slow. If you know a better way (or if I find one) it'd be very useful to document it.
