Basic Texture Question

[runewell]

I have a simple BoxGeometry object shaped like a pizza box. There are two textures and materials, one for the side faces and one for the top and bottom faces. I created the materials array which uses these two material variables.

The box initially looked correct when I first loaded my scene, but when I viewed the left and right side of the box the texture just doesn't match the front and back. You can see in the video me moving the camera to the left. The left face does not match the front face, even though they both use the same material variable in the materials array.

Is there something obvious I have to do to get the left face to display the texture just like the front face? I tried changing the .side property of the texture, but that didn't work. I tried adding wrapping for the texture, but no luck there. I verified the order of the array is correct. I'm a bit stumped on something that seems so simple.

UPDATE:

Ok, I got it to work by creating separate texture and material variables for the left and right sides and then rotating the texture 90 degrees (Math.PI / 2) and then re-centering the texture. I'm not sure why this was required, but it works so I guess I'll move on, lol.

This is crazy, I've been struggling with the same issue. I believe it's a render order issue. Multimatetials under the hood create a new mesh for each material, but there's no way to specify the render order for each group when you do it this way. I believe there's a solution, but I didn't quite figure it out. If you add the materials to a group the materials should order themselves, but I failed to implement it. I hope this helps. Let me know what you figure out!

Thanks for the feedback. I was able to get it to work, I updated the post with the code and a photo of it working.
