Bug workaround: buggy jpg encoders
Some newer websites and applications (such as GIMP) started to use a new jpg compression algorythm, which is not compatible for some unknown reason.
If the engine fails to load the jpg file, the texture will be missing, and the part of the model which contains the buggy jpg file, will be white.
I tried the latest version of the jpg decoder i use into Maker, but it not solved this, so i cant do anything with this problem.
Solution:
Save your image into a different format (like png), and if you wish, save it with another painting application into the jpg format. jpg files saved by mspaint, kolourpaint, xnview are usually good.
