SUBJECT: Using context 2I have been trying to load two textures into GS RAM, and set up one drawing context to each texture, that way I can switch between them easily by using a value of 0 or 1 for the CTXT field of the PRIM register. However, I can't get context 2 to work! :-(
Both textures are definitely being uploaded, because I can display either one using context 1. For context 1, I am setting the TEX0_1 and TEX1_1 registers. For context 2, I expected it to work if I simply used TEX0_2 and TEX1_2, but it doesn't work. The program runs, but it's just as if I never drew any primitives fr texture 2.
Are there some other context 2 registers that I need to set up, that sps2 doesn't set by default, e.g. FRAME_2, SCISSOR_2 etc.? |
