Hello Soft8soft Team,
I have a project where I must swap textures on an object. There are many textures and the catalog of textures will change over time. For these reasons, I do not want to include all of my texture files as part of the Blender file. I want to swap the texture with the API. If I can make this work, I could easily add new texture files to the web server and have the Verge3D scene apply them to the objects. This would simplify application maintenance.
My question is similar to c.j.yen’s question: Is there a way to change basecolor texture . I did try to use Ivan’s suggested code from that thread. Here is my slightly altered version.
app.ExternalInterface.setDiffuseMap = function(objectName, fileName) {
var myObj = app.scene.getObjectByName(objectName);
var mat = myObj.material;
new v3d.TextureLoader().load(fileName, function(tex) {
mat.map = tex;
mat.needsUpdate = true;
});
}
This does not work properly for me. When I run this function, the new texture file is applied, but my UV mapping is lost. Please see the attached screenshot. Here is a link to my working example ( example ). Click the thumbnail textures to apply them to the torus. When you click the thumbnail, the API code loads the correct image, but my carefully crafted UV mapping is lost.
The torus uses basic Blender materials. It does not use the node system. The project archive is included.
Is it possible to load and apply a new texture file and keep my UV mapping? Your help is much appreciated.
Thank you,
Jem
