From a4700549e065e86c3d42c93e73f76106f4054512 Mon Sep 17 00:00:00 2001 From: Antonio Vazquez Date: Fri, 28 May 2021 17:14:01 +0200 Subject: GPencil: Fix unreported random rotation for single point with texture When using ``Path`` alignment, if the stroke has one point the texture rotates randomly when move the viewport. This was because with one point is impossible to calculate a path. Now, if the stroke has only one point, the texture for this stroke is aligned to Object. --- source/blender/draw/engines/gpencil/shaders/gpencil_common_lib.glsl | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'source/blender/draw/engines') diff --git a/source/blender/draw/engines/gpencil/shaders/gpencil_common_lib.glsl b/source/blender/draw/engines/gpencil/shaders/gpencil_common_lib.glsl index 7412959a30b..ac48b94fea9 100644 --- a/source/blender/draw/engines/gpencil/shaders/gpencil_common_lib.glsl +++ b/source/blender/draw/engines/gpencil/shaders/gpencil_common_lib.glsl @@ -442,6 +442,10 @@ void stroke_vertex() if (is_dot) { # ifdef GP_MATERIAL_BUFFER_LEN int alignement = GP_FLAG(m) & GP_STROKE_ALIGNMENT; + /* For one point strokes use object aligment. */ + if (ma.x == -1 && ma2.x == -1 && alignement == GP_STROKE_ALIGNMENT_STROKE) { + alignement = GP_STROKE_ALIGNMENT_OBJECT; + } # endif vec2 x_axis; -- cgit v1.2.3
