Set_texture_projection

Developers Ruby API

What is the best method within pro 2022 to project an image onto a curved face? My extension is using set_texture_projection but that is not support any more. I can’t get face.position_material to create a smooth image across a curved plain. This is the error I get with projection.

This method never worked properly and was removed in SketchUp 2021.1. Use face.position_material with the projection vector instead.

I can’t seem to find any newer content on the web for how to handle curved surfaces within images for pro 2022.

I have a tutorial video about that topic, from basics to advanced plugins, it is Turkish language but i think it is understandable…

I will need to create the ruby script. You used an extension to create your work. I am looking for an example of how to do it in Ruby or even how to add a smooth image to a curved surface without using projection native within Sketchup Pro 2022.

Sorry, i didn’t noticed that it is ruby section… :slight_smile:

I would like to add an image across the front of a curved face. I can’t seem to get this code to work correctly. Any Ideas?

model = Sketchup.active_model
entities = model.active_entities


# Add the face to the entities in the model
points = [

face = entities.add_face(points)

face.position_material(material, ptsSpine0, true)

You aren’t passing any projection vector in this case. Notice the method has two overloads: Class: Sketchup::Face — SketchUp Ruby API Documentation

Btw, can you post example model and texture so we can run the example with the same data (model/texture).
