If you have recently updated your materials from v7 to v8+, you may have noticed the appearance of white spots or areas on your model. This is a result of a change in the shading type order, where the previously used Flat Shading has been replaced with ShadeMap, which is commonly used on Booth Models.

You can find all Shading types by navigating to the Lighting Type dropdown menu, located under Shading/Shading. Change it back to Flat, or whatever shading type it was on before.

Orca_Bubblez, Second reply, was wrong before. In the hierarchy, open clara, and go to body. in the inspector, you should see al of the pink shaders. Change them all to poi toon.

lexxieisnthere, Third reply, you also have to change the shaders for the Bodysuit object, the Harness Skirt, the hat, the Leggings and the Sleeves. For the staff, just click on the object in the scene and it will take you to it in the hierarchy. Leave the Tearsbottom and Tearstop material alone.

lexxieisnthere, Fourth reply, shaders are still messed up but better than nothing.

she is showing all pink, can someone help me, ive been trying all day to fix it and i cant
