I might be misreading, but, did you enable No Depth Test? If so that might be the issue. If not I made this StandardMaterial3D you can look though (Hopefully it helps, though, I haven’t used Sky3D and this shader might not work with it.) // NOTE: Shader automatically converted from Godot Engine 4.4.stable's StandardMaterial3D. shader_type spatial; render_mode blend_mix, depth_draw_opaque, cull_disabled, diffuse_lambert_wrap, specular_schlick_ggx, alpha_to_coverage; uniform vec4 albedo : source_color; uniform sampler2D texture_albedo : source_color, filter_linear_mipmap, repeat_enable; uniform float alpha_scissor_threshold : hint_range(0.0, 1.0, 0.001); uniform float alpha_antialiasing_edge : hint_range(0.0, 1.0, 0.01); uniform ivec2 albedo_texture_size; uniform float point_size : hint_range(0.1, 128.0, 0.1); uniform float roughness : hint_range(0.0, 1.0); uniform sampler2D texture_metallic : hint_default_white, filter_linear_mipmap, repeat_enable; uniform vec4 metallic_texture_channel; uniform sampler2D texture_roughness : hint_roughness_r, filter_linear_mipmap, repeat_enable; uniform float specular : hint_range(0.0, 1.0, 0.01); uniform float metallic : hint_range(0.0, 1.0, 0.01); uniform vec3 uv1_scale; uniform vec3 uv1_offset; uniform vec3 uv2_scale; uniform vec3 uv2_offset; void vertex() { UV = UV * uv1_scale.xy + uv1_offset.xy; } void fragment() { vec2 base_uv = UV; vec4 albedo_tex = texture(texture_albedo, base_uv); ALBEDO = albedo.rgb * albedo_tex.rgb; float metallic_tex = dot(texture(texture_metallic, base_uv), metallic_texture_channel); METALLIC = metallic_tex * metallic; SPECULAR = specular; vec4 roughness_texture_channel = vec4(1.0, 0.0, 0.0, 0.0); float roughness_tex = dot(texture(texture_roughness, base_uv), roughness_texture_channel); ROUGHNESS = roughness_tex * roughness; ALPHA *= albedo.a * albedo_tex.a; ALPHA_SCISSOR_THRESHOLD = alpha_scissor_threshold; ALPHA_ANTIALIASING_EDGE = alpha_antialiasing_edge; ALPHA_TEXTURE_COORDINATE = UV * vec2(albedo_texture_size); } (Also, I suggest checking if you made the leaves transparent in GeometryInstance3D, as it having transparency can also cause issue)

I have this code. Also I see what is causing it. When there is a background then the leaves are normal but when the tree is with the sky behind it then is transparant. I use sky3D and I guess it is something with that because when disable that Sky3d it is normal. // NOTE: Shader automatically converted from Godot Engine 4.3.stable.mono's StandardMaterial3D. shader_type spatial; //render_mode blend_mix, depth_draw_opaque, cull_disabled, diffuse_burley, specular_schlick_ggx, depth_prepass_alpha; render_mode blend_mix, depth_draw_opaque, cull_disabled, diffuse_lambert_wrap, specular_schlick_ggx, depth_test_disabled; uniform vec4 albedo : source_color; uniform sampler2D texture_albedo : source_color, filter_linear_mipmap, repeat_enable; uniform float point_size : hint_range(0.1, 128.0, 0.1); uniform float roughness : hint_range(0.0, 1.0); uniform sampler2D texture_metallic : hint_default_white, filter_linear_mipmap, repeat_enable; uniform vec4 metallic_texture_channel; uniform sampler2D texture_roughness : hint_roughness_r, filter_linear_mipmap, repeat_enable; uniform float specular : hint_range(0.0, 1.0, 0.01); uniform float metallic : hint_range(0.0, 1.0, 0.01); uniform sampler2D texture_emission : source_color, hint_default_black, filter_linear_mipmap, repeat_enable; uniform vec4 emission : source_color; uniform float emission_energy : hint_range(0.0, 100.0, 0.01); uniform vec3 uv1_scale; uniform vec3 uv1_offset; uniform vec3 uv2_scale; uniform vec3 uv2_offset; uniform float sway_speed = 1.0; uniform float sway_strength = 0.05; uniform float sway_phase_len = 8.0; void vertex() { UV=UV*uv1_scale.xy+uv1_offset.xy; float strength = COLOR.b * sway_strength; VERTEX.x += sin(VERTEX.x * sway_phase_len * 1.123 + TIME * sway_speed) * strength; VERTEX.y += sin(VERTEX.y * sway_phase_len + TIME * sway_speed * 1.12412) * strength; VERTEX.z += sin(VERTEX.z * sway_phase_len * 0.9123 + TIME * sway_speed * 1.3123) * strength; } void fragment() { vec2 base_uv = UV; vec4 albedo_tex = texture(texture_albedo, base_uv); ALBEDO = albedo.rgb * albedo_tex.rgb; float metallic_tex = dot(texture(texture_metallic, base_uv), metallic_texture_channel); METALLIC = metallic_tex * metallic; SPECULAR = specular; vec4 roughness_texture_channel = vec4(1.0, 0.0, 0.0, 0.0); float roughness_tex = dot(texture(texture_roughness, base_uv), roughness_texture_channel); ROUGHNESS = roughness_tex * roughness; // Emission: Enabled vec3 emission_tex = texture(texture_emission, base_uv).rgb; // Emission Operator: Add EMISSION = (emission.rgb + emission_tex) * emission_energy; ALPHA *= albedo.a * albedo_tex.a; }
