Texture updateSamplingMode issue


Recommended Posts

It seems like texture.updateSamplingMode() doesn't actually work (though looking through the code, it looks like it should, as it's making the right gl calls).


I noticed this as loading a .babylon file with sampling mode set wasn't working (though the samplingMode property on the texture would be correct, it was not rendering in that mode).

(And assuming that it should work, https://doc.babylonjs.com/resources/file_format_map_(.babylon)#textures should probably be updated to include the samplingMode property)

I looked deeper at the issue and it requires : https://github.com/BabylonJS/Babylon.js/issues/4746 this one to be addressed first.

As you have 2 workarounds:

- Pass the information through the constructor

- Update once the texture has been loaded

I ll fix it as part of the texture issue on Github (I updated the issue already). 

Please @sable let me know if that works for you.

Yeah my use case is loading a model (.babylon format), and then applying a customMaterial to it (so I can modify the shaders). I was trying to just attach the texture from the original material to this new material and just update the sampling mode when I ran across the issue (after discovering that setting the sampling mode in the .babylon file was also didn't work).

My workaround was to just extract the url and make a new texture, which I'll continue to do for now, as even waiting for the texture to load doesn't seem to always work.

Thanks for looking into this.
