Hi, i''m writing a *.x Importer for OpenGL at the moment... I''ve loaded all the Frames etc correctly, but... anyframe in the X-File has an own Matrix, and I don''t know how/when to call them.. Let''s say we have this: Frame A - Frame B (Child of Frame A) - Frame C (Child of Frame A) - Frame D (Child of Frame C) So, if I render Frame D.. have I to multiply the Matrices from Frame A and C too??? and, in what direction... A->C->D or D->C->A...??? Please help.. Au''revoir, Aya~
