Hello
I'm new to PB and trying to figure out a question like this.
Found the old post on this forum https://www.purebasic.fr/english/viewtopic.php?p=554915 about how to do texturing of 3D model with STL extension. Went through all the steps one by one until the moment where I have to accept the defaults in UVMapper Classic. The model had to appear on the screen and I had to save it in OBJ format. However this did not happen, I tried it several times, nothing. What could be the problem, the original 3D model itself or UVMapper? Can anyone advise another software to try and do the same thing or some other way for texturing the 3D model with STL extension?
This is a new area for me, wandering in the dark for now.
Thanks in advance for your answers

The model is too big. 1.3+ million poly's. UV Mapper is designed for smaller game type models with thousand of poly's
Options, I can think of three
- cull the poly count down severely using a mesh editor or online tool.
- or use a different app to UV map the model. eg blender, meshlab
- or find a different model

ADDED I've reduced the models polygon count to 10% It does load, after a while, into UV mapper. It's still to big for a game model, you can (hopefully) download it from here if I have set it up right - https://1drv.ms/u/s!AqdGEnoIfPMm4FCYGXa ... 0?e=bLeZXB

Try running your original model through this open source polygon reducing software. They target getting models less than 1 million poly's. It imports/exports a large number of file formats

With Blender you can decimate huge models very easy with the decimator modifier.
