Finally got it to work. Have to use P3D renderer. The following gives a yellow rotating mobius (needs more work):
PShape mobius;
float ry;
void setup() {
size(400, 400, P3D);
background(209);
mobius = loadShape("mobius.obj");
mobius.setFill(color(255, 255, 0));
ry = 0.85;
}
void draw() {
background(209);
translate(width/2, height/2, 100);
rotateZ(PI);
rotateY(ry);
scale(4.0);
shape(mobius);
ry += 0.02;
}
Blender is an impressive app. The good news is that it will convert from .stl to .obj without having to use an online converter. It also includes an accompanying .mtl file automatically.

@glv @svan now it’s working!!
How did you get the setTexture to work in processing.js? @glv
My 3d model is now loading and visible with setFill, but the setTexture is not working.
“txt cannot be resolved to a variable”
mobius.setTexture(txt);

Works fine with Processing 4.1.1:
Be careful with names… I used txt and you had txtr in your examples.

When using the following code, my 3d model turns back to black even when using Processing 4.1.1
mobius.setTexture(txtr);
PShape mobius;
PImage txtr;
float theta;
void setup(){
size(1000,1000,P3D);
txtr = loadImage("grid3.jpg");
mobius = loadShape("ring2obj.obj");
mobius.setTexture(txtr);
}
void draw() {

pushMatrix();
translate(width/2, height/2);

lights();
rotateY(mouseY);
rotateX(mouseX);
//rotateZ(theta/2);
scale(90);
shape(mobius);
popMatrix();
theta+=.01;

I added the data in my moebius.obj file in my previous post.
Which one did you use? I tried a few until I got acceptable results.
Be careful when exporting with Blender and copying the files to the Processing sketch… I made a few errors in the beginning and very methodical now about this.
:)
@glv oh I see! I’m not sure what to select after selecting UV> Cube Projection?
Are there further options before exporting?
I’ve been selecting UV> Cube Projection then exporting and nothing else.
glv:
mobius.setTexture(txtr);
When I use the same code as you… I get the following results. setTexture still is not working?

So that we are comparing the same thing…
Try it with the moebius.stl here:
A moebius ring, after a few trials, this is what worked for me :
shell 2mm
infill 20%
Support ( cura ) overhang angle : 50°
Printed at 70mm/s .2mm resolution.
I tried no infill, forget about it, you'll waste plastic ;)
1.2mm shell was too thin in...
Use this image:
txtr = loadImage("http://learningprocessing.com/code/assets/sunflower.jpg");
I also updated a previous topic to include code and the moebius.obj file that works for me.
Pay attention to the geometry selections when exporting.
There is a learning curve to all of this and I went through it… I did a lot of research to understand all of this and some mistakes along the way.
Have fun!
:)
Hi @glv ! When I use the same 3d model and code as you, the setTexture is still not applying an image?
After selecting “UV > Cube Projection” do I need to select anymore options?
When exporting to an .OBJ file I have the same geometry selected as you.

Hello,
The fact that it is green means something is being textured from the image!
These are the notes I have in my code:
// Blender import:
//
// Delete cube and other stuff
// import Stl(.stl)
// Edit mode
// Cube projection
// Export Wavefront (.obj) with Geometry:
// UV coordinates
// Normals
//
// Make sure you are exporting it to a know location!
// Easy to mix up the exported files.
There are experimental and legacy options… do not use these!
I am not a Blender expert and much of this was research to understand what was going on, persistence, perseverance and trial and error.
All that to get a visible texture on a shape in Processing!
That is just the tip of the iceberg when it comes to mapping textures in Blender or in Processing.

To sharpen our skills with lighting, color and materials in Processing’s 3D renderer, it’s helpful to have a model more complex than a…

You don’t have to do all that. All you really need is an .obj, .mtl, and graphic file (.jpg or .png) and a little Processing code as shown in Files/Examples/Basics/Shape/LoadDisplayOBJ :
PShape rocket;
float ry;
public void setup() {
size(640, 360, P3D);
rocket = loadShape("rocket.obj");
}
public void draw() {
background(0);
lights();
translate(width/2, height/2 + 100, -200);
rotateZ(PI);
rotateY(ry);
shape(rocket);
ry += 0.02;
}

The original poster was importing an STL to Blender and exporting an OBJ and attempting to texture it with Processing.
I was assisting with that pursuit.
There is a nice definition of an STL file here:
This format describes only the surface geometry of a three-dimensional object without representing color, texture, or other common model attributes.
The challenge presented was to start with an STL, export to an OBJ and texture it.
It can be textured in Blender and exported or textured in Processing.
Only an STL file in this:
A moebius ring, after a few trials, this is what worked for me :
shell 2mm
infill 20%
Support ( cura ) overhang angle : 50°
Printed at 70mm/s .2mm resolution.

My point was you don’t have to do all that with Blender; it’s an impressive app but it’s complicated. STL files can be converted to an .obj file with an online converter. The difficult part is getting the .mtl file. There are online repositories of .obj files and ideally the .mtl file comes with it. Otherwise I have re-purposed an .mtl file of one of Processing’s examples with limited success; not an ideal way to do it. In my opinion the reason the poster has had so much trouble is because the .mtl file was created in Blender and did not take into account the special images that were attempted to be added later. The .mtl file sets the texture normally. eg In the Processing example that I posted here is the .mtl
newmtl Default

Hello @asymmetric ,
Thanks for this topic! I am having some fun with Blender! :)
For clarity…
I have not been texturing in Blender with an image and not exporting OBJ with materials (MTL file along with an image).
I have been:
Importing an STL.
Exporting an OBJ without an MTL file (materials not selected
Texturing in Processing to the UV selected in Blender for the OBJ file. There is a whole menu of choices there!
I managed to “hide” one side of the moebius against the background like a chameleon:
When moved:
Blender UV Project from View (bounds) Cube Projection
There are a lot of tutorials but I found this the most helpful for me at 0.75 speed:
I am still new at using Blender but a quick study and there is a steep learning curve; I am familiar with similar tools so it was not so bad.
I just wanted to share the possibilities!
Have fun!

You will have to supply a texture image of your choice.

Nice obj. Textures up easily. No .mtl file?
I noticed that your obj file had no mtllib xxxx.mtl line of code at the top. Did you delete it or was it just not put there by Blender? Apparently if that line is not there it makes it easier for Processing users to add their own textures.
Below is a file that I created in Blender from an imported .stl and edited using the Project from View setting. It included an .mtl file with the exported .obj file, but if I REM out the mtllib line out of the first line of the .obj file then I can also easily add my own texture just like I did with your obj file.
In summary, apparently if you leave out the .mtl file (ie mtllib reference to it in obj file) it’s possible to add your own texture easily. It also looks like this only works if you create the .obj file in Blender. I didn’t have similar luck using an online converter (stl to obj).
Addendum: no .mtl file :
Second Addendum: blank .mtl file when using Project from View so you don’t really have to REM out the first line of the obj file; it will also work with your own graphic file just as easily if you leave the first line in place in the .obj file.
