How to export a file with color

[kwjaarsveld-star]

In Tinkercad I export a 3D object with color as .obj file.

In layerling that does not work(?) I get a .obj file, but there is no color getting with that file when I import it in the slicer.

I also tried .3mf, en that's the same; no color. So, how do I get my colors in the slicer??

Thanks for the report, this was a bug in layerling.

Before exporting, layerling joins bodies that overlap or touch into one, so the slicer gets clean shells. That also joined bodies of different colours, and the joined body kept only the colour of the first one. That is why your white logo came out black. OBJ files from layerling also carried no colour at all.

Both are fixed in the next version. Only bodies of the same colour are joined now. Where one colour sits inside another, the body you built first leaves room for the later one, so your logo stays whole and the holder gets a matching pocket. 3MF keeps the colours as before. OBJ now stores them as vertex colours in the same file, so no extra .mtl file is needed. Bambu Studio and OrcaSlicer read both formats and ask how to map the colours onto your filaments.

Please check if it works for you after it is published in a few hours, thanks!

Thanks for checking! You're right, and it wasn't only colours: the OBJ import didn't read them at all, so every OBJ came in as a single body in the default blue. That's why your logo disappeared into the holder.

Fixed in the next version: a coloured OBJ now comes in as one body per colour, each in its place. layerling reads the vertex colours of its own OBJ files and the materials of an OBJ with an .mtl. For a file from Tinkercad, import the whole ZIP you download there, or select the .obj and .mtl together. While at it I found that re-importing an OBJ exported from layerling laid it on its side; that's fixed too.

I'll post here once it's live.

it's live now in 1.30.0 on layerling.com. Reload the app once, or close and reopen it if you use the installed version.

OBJ: A coloured OBJ now comes in as one body per colour, each in its place. That works for layerling's own OBJ files and for OBJ files with an .mtl. For a file from Tinkercad, import the ZIP you download there, or select the .obj and .mtl together.
3MF: A coloured 3MF does the same. It takes the colours stored in the file, or in a Bambu Studio, OrcaSlicer or PrusaSlicer project the filament of each part. Colour painted onto faces in the slicer isn't read yet.
Upright again: An OBJ exported from layerling now comes back upright instead of lying on its side.

Thanks again for testing so thoroughly. Let me know how it works with your keychain!

You are To Fast!! 😄

so it works now as expected?

Completely. I'm printing some exported stuff now.
