enkonyito, did you export and load all the YafaRay DLLs required for the plug-in, like in the [font=courier new]loadDLLs[/font] method I programmed in [font=courier new]YafarayRenderer[/font] class?

Yes, otherwise it causes the error [font=courier new]java.lang.ExceptionInInitializerError[/font] .

What would prevent access to native methods in this case ([font=courier new]java.lang.UnsatisfiedLinkError[/font] ) ?
