Guidance on Applying Texture to a Targeted Area of a 3D Model in Three.js

Currently immersed in a Three.js project, I find myself faced with the challenge of projecting a texture onto a particular surface of a 3D model. Despite loading the model through GLTFLoader and possessing the necessary texture, my attempts at using Raycasting and UV mapping have proven to be fruitless.

I seek guidance on how to effectively project the texture onto a specific area of the 3D model's surface. A detailed explanation or code snippet outlining the process would be greatly appreciated.

I welcome any tips, examples, or resources that can aid me in achieving this goal. Thank you for your anticipated support!

Demonstrations and explanations showing the projection of textures in three.js onto precise surface areas.

Answer №1

In three.js, when it comes to working with textures on models, you have a couple of options. The first is UV unwrapping, which involves preparing the model in a software like Blender and then exporting it to be compatible with three.js. If you're new to UV unwrapping, there are plenty of tutorials online that can guide you through the process more effectively than a written explanation.

Another technique you can use is applying decals directly onto the surface without altering the UV mapping. For an example of how this can be done, along with code snippets and detailed instructions, check out the links on the official three.js website:
