I can't put two textures together with alpha. Illustration n1.
Is it possible to fold them as in the illustration n2?

shader_type spatial;
uniform sampler2D texture1 : hint_albedo;
uniform sampler2D textureBlood : hint_albedo;
void fragment() {
vec4 texture1_ = texture(texture1, UV.xy);
vec4 textureBlood_ = texture(textureBlood, UV.xy);
float texMixAlpha = 0.00000;
vec4 texMix = mix(textureBlood_,texture1_,texMixAlpha);
vec3 emission_ = texMix.rgb;
EMISSION = emission_;
}
