i also tried making a 'fake wind' shader, but its useless, as the editor becomes really, really slow.
and the vertices dont get displaced correctly, it seems they get calculated from the pivot point of the mesh
shader_type spatial;
render_mode blend_mix, depth_prepass_alpha, cull_disabled, diffuse_burley, specular_schlick_ggx;
uniform float alphatreshold;
uniform float strenght : hint_range(0.0, 1.0, 0.05);
uniform float speed : hint_range(0.0, 1.0, 0.1);
uniform sampler2D colortex : source_color,filter_linear_mipmap,repeat_disable;
uniform sampler2D normaltex : hint_roughness_normal,filter_linear_mipmap,repeat_disable;
uniform sampler2D roughnesstex : hint_roughness_gray,filter_linear_mipmap,repeat_disable;
void vertex() {
VERTEX.x += sin(TIME * speed + VERTEX.x + VERTEX.z ) * strenght * COLOR.g;
VERTEX.y += sin(TIME * speed + VERTEX.y + VERTEX.x ) * strenght * COLOR.g;
VERTEX.z += sin(TIME * speed + VERTEX.z + VERTEX.y ) * strenght * COLOR.g;
}
void fragment() {
ALPHA = texture(colortex,UV).a;
ALPHA_SCISSOR_THRESHOLD = alphatreshold;
ALBEDO= texture(colortex,UV).rgb;
NORMAL_MAP = texture(normaltex,UV).rgb;
METALLIC = 0.0;
SPECULAR = 0.5;
ROUGHNESS = texture(roughnesstex,UV).r;
}
