people imagine you have a parallax map texture that when you get to the corner the polygon shows the depth and the texture plus the contour and something with a triangle space many polygons like a theselation but without polygons with a transparency and keeping the shape with the relief of the texture in the Z check it out and this would be a material that shows the texture for example if you put a plane but it has a texture of a stone or a floor with stone you can remove it with the force of the normal map and it would even show a sphere from above but half of the side where I have a plane if the sphere is in the right Z it appears the tip in the center of the sphere but if you have a stone or floor model instead of seeing the corner don poligono you will see the relevo of the "paralexmap" plus the Z and the transparency on the corners showing the texture of the floor as if you focus on many polygons but being a pixel instead of polygons, do you understand? give your comments and let's go ahead that brings vemgente!
