material change on imported mesh

[boris]

Hi guys.

i got 2 little questions that are bothering me:

1. im importing an .obj model with assetManager, and onSuccess im trying to iterate through all of the models meshs and change their material texture's to a new texture. but i just does nothing. http://www.babylonjs-playground.com/#2GVUDN .

BUT, if i save the loaded model and create a function that runs after about 15 seconds that tries to do create new textures for all the meshes it does it succefully.

what am i missing here?

 

2. in that same link, how can i prevent the arc camera from going below the house? that means keep it always above 0 (y>0)

 

thanks.

@boris; Hi boris, welcome to the forum

For controlling the ArcRotate camera you can use this kind of code:

myScene.registerBeforeRender(function () {		            
	if (myCamera.beta < .75) myCamera.beta = .75;
	else if (myCamera.beta > (Math.PI / 2) * 0.66) myCamera.beta = (Math.PI / 2) * 0.66;       
});

I got the code originally from something @Dad72 posted..  Play around with the beta values to meet your needs.

I have no experience with loading .obj files directly - but others can help I'm sure.

cheers, gryff

thanks @gryff ! i will try that immediately.

 

btw, about the first question it goes the same with .babylon objects.

i tried both of them, usually i work with .obj so that what was in example
