Overlaying Semi Transparent Texture Over A Material Materials . ), made completely from scratch, or contributed by the community. Pour une normal map, il faudra également, dans Textures / Image Sampling, cocher Normal Map. Texture files can have a transparency value, and as such we’d like to use it on occasion with 3D objects.
