Can Render Material Color in runtime to dynamically loaded model

Help & Support
17

Sure, if you select the right material and that material uses a diffuse color. Then it will.

18

You can see that here that we are implementing material on run time So how will i do the referencing for that ?

19

I don’t see any difference, if it’s a Playcanvas material just do the same:

var material = this.entity.model.meshInstances[0].material;

material.opacity = 1.0;
material.diffuse.fromString('#F4CB01');
material.update();

Getting this error :
TypeError: Cannot set property ‘opacity’ of undefined

21

Can you post your code please?

22

Nevermind, I see your code here:

    this.entity.addComponent("model"),
    this.entity.model.model = d,
    this.entity.model.meshInstances[0] = this.Mymaterial.resource,
    product = this.entity;
    var u = this.entity.model.meshInstances[0].material;
    u.opacity = 1,
    u.diffuse.fromString("#000000"),
    u.update()

This line is odd

this.entity.model.meshInstances[0] = this.Mymaterial.resource

Why is app setting a material to a meshInstance?

What’s not working? I didn’t post a fix to the code, just pointed out where the code I saw in your app that doesn’t look right.

Sorry, you need to be clearer about

  • what your problem is (if you are still getting problems)
  • what your error is
  • which project or webpage you are getting it
  • how to reproduce the error

We are creating Product configurator where we are importing models on runtime that’s working fine(http://network.daruldev.com/Edit-3d-models/12) and also creating material on runtime that’s also working fine(http://network.daruldev.com/Edit-materials/1) But when we are implementing that material on model here(http://network.daruldev.com/Edit-product_variations/2) Its not working. That’s the main problem.

Not showing any error on material.opacity and so on
