Convert Texture To Normal Map Code From Scratch

With a normal map, it can in some ways defy the laws of physics when it comes to height which is why most accurate maps are typically a combination of height and normal.Specular map texture is like you know it in Unitys Standard Shader. Within the Texture Inspector, un-checking sRGB (Color Texture) converts the.Normal Map online can be sued to create normal, displacement, ambient occlusion and specular maps from a simple height map image. NOTE: script will close MEditor before start converting process. > Update v1.7 : - rewritten code from scratch - supports max 2017 and vray 3+ NOTE: all new parameters of VRay NormalMap will be converted to standard normal map and vice versa.

The first app that comes to mind is Substance Designer which has a node for this but as much as I love substance and basically live in it, even substance doesnвЂ™t вЂњnail itвЂќ per se. There are a few apps out there that allow you to convert maps online and some you can download. I usually find the effect to be gimmicky at best but my standards (at least the ones I hold myself at) are usually pretty high so take that opinion with a grain of salt.

The problem ofcourse is that this way the normals are totally wrong as shown in the image below.Is there a way to make blender recalculate the normals to be correct for the way they are projected on the object? Or isn't this possible at all? Or is there another way to achieve this?As I see it, there is a problem with all these solutions because they all cause the pinching together of the woodgrain as well as the taperingВ of the joining grooves.В That affects both diffuse and normal. To get the texture to follow the curve of the round corners I mapped them the way shown below.When I bake the normal map in blender it's the original normal map transformed to fit the object the same way the diffuse and specular texture does. I'm probably going the wrong way about this and I don't know if what I'm trying to achieve is even possible at all?В I'm asking for your input on this because I'm out of ideas and I can't seem to find an answer anywhere.This is the object and the UV mapping of the part in question.I bought a woodlplank texture on MP which came with normal and specular maps. I have been working on a set of modular walkways and I'm having trouble with gettingВ the normal mapsВ on the round corner pieces to work correctly. While both tools are easy to use, you can see both of them in action in the video below.blender bake normal map from texture, A quick demonstration how to bake. If you bake a 16-bit map, youll likely need to convert to 8-bit color for the.Long story short, I think for your application, you might find it easier than you think just to make the maps yourself from scratch and go from height to normal, which is totally doable with a great deal of accuracy as opposed to the other way around.

Both were completely smooth shaded. The edges of the high poly were extended to overlap the low poly to suppress some edge artefacts. Low poly orange, high poly black (they were joined just to make this picture, separate objects for baking). Lastly, the combination of texture bake and ao (multiply).Next, some details of the meshes. Below that, the results of baking selected (high-poly) to active (low poly) textures, normals and ao. Top two are diffuse and normal maps applied to the high poly mesh.

The gap between the planks got tapered as well, something you wouldn't expect to see in RL.В The woodgrain also got stretched a lot on the outer edges when mapping it the way I did.В Your solutionВ to this problemВ works perfect! I like the idea of starting with a plain wood grain texture. You're guide has a very clear and simple workflow with a lot of great tips to circumvent some problems I would definetly have run into, like extending the edges on the high poly model and the aligning of the UV islands to the woodgrain.I also noticed the pinching of the woodgrain and normal maps and it gives quite a few artifacts (besides from not looking correct in the first place. I'm going to go this route because the end result looks so much cleaner and more realistic. Should probably omit the grain normal from the grooves.Thank you so much Drongle for this wonderfull and comprehensive guide!I have been thinking of using a high to low poly bake but I have never done this before and was a bit hesitant to try. I guess because adding the normals from the woodgrain to that of the groove surfaces sometimes produced some normals pointing into the low poly mesh, which is not allowed.

It will give me a lot more control over the outcome as well.
