RC20s are the sole cause of a modders distress, and confusion, let;s not lie about that. I know a few ways to try and fix them are as follows: Attach as many objects as possible, etc. Delete the models .wft, and reimport the base model. Re export the enitre scene just to make sure it exports properly. and several other small techniques. But none of the following have worked for me, and it makes me very sad. Does anybody know A.) How to fix an RC20. or B.) What an RC20 actually is?

RC20 also occures when you have missing shader configurations, which means you have for example a polygon, but its not assigned to a material. Mostly when you export your ZModeler should mention you that you have wrong shader configs.

Would you mind explaining some about the shader configurations to me, and if not, do you know anybody who would? Much appreciated.
