WARNING: The texture Models/Tank/Tank_Occ_Rough_Metal.png has linear color space, but the material parameter LightMap specifies no color space requirement, this may lead to unexpected behavior.
Check if the image was not set to another material parameter with a linear color space, or that you did not set the ColorSpace to Linear using texture.getImage.setColorSpace().

The 2nd time I tried, it worked fine. This is reminiscent of an issue I saw last year but hadn't seen recently. Timing-dependent?

Now it's happened 2 times out of 3.
