From 54a0d834dc942ae051d28623a522c72fedf68f1c Mon Sep 17 00:00:00 2001 From: skal Date: Sat, 14 Feb 2026 00:47:01 +0100 Subject: gen_identity_weights: Add --mix option for static feature blending MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds --mix flag to blend input channels with static features: - p0+p4 → p0 (RGBA + UV.x) - p1+p5 → p1 (RGBA + UV.y) - p2+p6 → p2 (RGBA + sin encoding) - p3+p7 → p3 (RGBA + bias) Useful for debugging static feature contribution in CNN v2. Updated doc/CNN_V2_DEBUG_TOOLS.md with --mix usage examples.
