From 4b08b9c3e9da922d80aaff4720ed2dec026c012e Mon Sep 17 00:00:00 2001 From: Oliver McFadden Date: Thu, 12 Jul 2007 23:52:06 +0000 Subject: [PATCH] r300: Setup the back facing color bits correctly. Apparently for back facing color to work you must set all 3 color bits; I guess the hardware cannot handle them separately. --- src/mesa/drivers/dri/r300/r300_emit.c | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) diff --git a/src/mesa/drivers/dri/r300/r300_emit.c b/src/mesa/drivers/dri/r300/r300_emit.c index 732dbcbc9d9..424bf44e595 100644 --- a/src/mesa/drivers/dri/r300/r300_emit.c +++ b/src/mesa/drivers/dri/r300/r300_emit.c @@ -299,11 +299,12 @@ GLuint r300VAPOutputCntl0(GLcontext * ctx, GLuint OutputsWritten) if (OutputsWritten & (1 << VERT_RESULT_COL1)) ret |= R300_VAP_OUTPUT_VTX_FMT_0__COLOR_1_PRESENT; - if (OutputsWritten & (1 << VERT_RESULT_BFC0)) - ret |= (7 << 2); - - if (OutputsWritten & (1 << VERT_RESULT_BFC1)) - ret |= R300_VAP_OUTPUT_VTX_FMT_0__COLOR_3_PRESENT; + if (OutputsWritten & (1 << VERT_RESULT_BFC0) + || OutputsWritten & (1 << VERT_RESULT_BFC1)) + ret |= + R300_VAP_OUTPUT_VTX_FMT_0__COLOR_1_PRESENT | + R300_VAP_OUTPUT_VTX_FMT_0__COLOR_2_PRESENT | + R300_VAP_OUTPUT_VTX_FMT_0__COLOR_3_PRESENT; #if 0 if (OutputsWritten & (1 << VERT_RESULT_FOGC)) ; -- 2.30.2
