Mar 14, 2015 · That normal map is in tangent-space, but you are treating it as object-space. You need a bitangent and/or tangent vector per-vertex in addition to your normal in order to form the basis to perform transformation into and out of tangent-space.

Nov 25, 2024 · Normal map vs bump map Is there a particular reason why you turned your bump data into a normal map? Bump is an elevation data, normal map is an orientation data, so I wouldn't expect to get an equal result from each other. To illustrate, I did a mockup of your scene: made a brick texture, plugged into a bump node, then into a Principled BSDF, then baked that …

Aug 20, 2022 · A normal map and a bump map do the same ultimate thing: they change the angle of a sample, which affects how light reflects off of it. However, they use different ways to get there. A bump map is a black and white map of height. It can be used either in a displacement node (for material-wide bump mapping, depending on material settings) or in a bump node (potentially, …

Aug 5, 2015 · I have been trying to make normal maps work in three.js, but to no avail. Although there are already questions asking this (including Three.js Normal Mapping forcing mesh to not render and How to m...

Jan 11, 2021 · You need a Normal Map Node between the Image Texture and Principled Shader. Now beware that this Strength parameter is in units at the scene scale, so most likely by default this is going to try to make it appear such that the highest point is jutted out by an entire meter.

Mar 12, 2011 · I'm working on procedurally generating patches of dirt using randomized fractals for a video game. I've already generated a height map using the midpoint displacement algorithm and saved it to a te...

Jun 30, 2014 · I have a normal map which is 'looking in a wrong direction' and I would like to get exactly opposite effect that this map gives in my Cycles render. Is it possible?

Aug 13, 2013 · Without normal-mapping, the lighting system works fine. I'm using the normals forwarded from the vertex shader, and they work perfectly fine. I'm also reading the normals from the normal map correctly. Without including the normal map, the lighting works perfectly. I've tried adding the vertex normal and the normal map's normal, and that doesn ...

May 14, 2021 · There are some "Normal Map" textures that have a limited strength, even putting the input of the "Normal Map" node at maximum 10. I was wondering what would be the best solution, using nodes, to accentuate the strength of the Normal map, before entering the input of the "Normal Map" node, so as to better adjust the strength.

Sep 26, 2017 · I am trying to implement making making flake normal map texture like this. flake normal map texture I have found this page. In the page, there is a OSL code, and I tried to implement with GLSL. ...
