My issue related to building a material with node material.
I build material block by block and also apply .png files to Texture blocks.
On the screenshot below you can see, that all of the texture blocks have it’s own .png.
But if we look at the preview on the right/bottom, we see, that textures applies incorrectly.
Btw, issue has gone, when i set the fourth parameter of addTextureTask to false explicitly.
But that’s strange, cuz docs says, it is false by default.
loader.addTextureTask(textureName, url, false, false));
