From 7061c28df7bac641351431af20342b44fc439fd5 Mon Sep 17 00:00:00 2001 From: brendor Date: Tue, 20 Mar 2018 01:28:41 +0100 Subject: Particles 2D and 3D - fix hue variation not working by transposing the hue matrix The hue variation matrix is hardcoded as transposed and thus the multiplication always yielded the original color value. I wanted to keep the matrix and get the same result by switching the operands (getting a result as if the matrix was transposed). --- scene/3d/particles.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/scene/3d/particles.cpp b/scene/3d/particles.cpp index 8617bbc2f6..693b416f6d 100644 --- a/scene/3d/particles.cpp +++ b/scene/3d/particles.cpp @@ -849,9 +849,9 @@ void ParticlesMaterial::_update_shader() { code += " vec4(1.250, -1.050, -0.203, 0.0),\n"; code += " vec4(0.000, 0.000, 0.000, 0.0)) * hue_rot_s;\n"; if (color_ramp.is_valid()) { - code += " COLOR = textureLod(color_ramp,vec2(CUSTOM.y,0.0),0.0) * hue_rot_mat;\n"; + code += " COLOR = hue_rot_mat * textureLod(color_ramp,vec2(CUSTOM.y,0.0),0.0);\n"; } else { - code += " COLOR = color_value * hue_rot_mat;\n"; + code += " COLOR = hue_rot_mat * color_value;\n"; } if (emission_color_texture.is_valid() && emission_shape >= EMISSION_SHAPE_POINTS) { code += " COLOR*= texelFetch(emission_texture_color,emission_tex_ofs,0);\n"; -- cgit v1.2.3
