How to create a material in grasshopper from an image

How to create a material in Grasshopper with an image, also I need to adjust mapping scaling, rotation

[martinsiegrist]

Using native components, this is not possible yet.

What you can do is create the material in Rhino and the reference it in Grasshopper.

Just write the material name into a text panel and plug it into the Material input of the Custom Preview

Thankyou for the reply,

I’m already using that way, but there is a problem that, I had to redo 'the select one material ’ process everytime I update texture mapping. I m not getting a live preview until baked, i specifically need the road texture applied to full stretch along the road following curves of road also. Is there any solution.

Hello
you will find some discussions on this forum if you search with “texture” keyword

Texture in grasshopper

I want to know , how to apply texture with mapping to an object in grasshopper , I tried Human plugin , but not working for me ? texture file.gh (7.7 KB)

Mapping textures inside Grasshopper

thank you. I’ll try it

Here a simple way of doing using some C#, could be Python. I am not sure it is the last Material but it works.
You will find some way of changing texture like here

material.gh (9.8 KB)
You can add easily others texture not just the diffuse but the bump …

private void RunScript(System.Drawing.Color Colour, double Reflection, double Smoothness, string filename, Transform transform, ref object Mat)
  {
    Reflection = Math.Min(Math.Max(Reflection, 0), 1);
    Smoothness = Math.Min(Math.Max(Smoothness, 0), 1);
    Rhino.DocObjects.Material material = new  Rhino.DocObjects.Material();
    //material.SetBitmapTexture(fileName);
    material.ReflectionColor = Colour;
    material.DiffuseColor = Colour;
    material.AmbientColor = System.Drawing.Color.Black;
    material.EmissionColor = System.Drawing.Color.Black;
    material.Reflectivity = Reflection;
    material.ReflectionGlossiness = Smoothness;

    Rhino.DocObjects.Texture text = new Rhino.DocObjects.Texture();
    text.ApplyUvwTransform = true;
    text.UvwTransform = transform;
    text.FileName = filename;
    material.SetTexture(text, Rhino.DocObjects.TextureType.Diffuse);


    var renderMaterial = Rhino.Render.RenderMaterial.CreateBasicMaterial(material);
    Mat = new GH_Material(renderMaterial);
  }

Thank you very much @laurent_delrieu for the custom component

Thank you very much @laurent_delrieu
I would appreciate anyone who can help
I know this is an old question
But I needed the subject now urgently
I don’t know Grasshopper and I need to have a bump map on a certain surface
How do I use my image to make the texture I need?
including bumps
Thank you again,
Chaya

I don’t know Grasshopper

But do you know Rhinoceros and the basics of texturing ? It is far from clear why you need Grasshopper. With so little information I am not sure someone could help you.

@laurent_delrieu

basics of texturing

@laurent_delrieu Thank you very much for the quick reply
Rhinoceros I know perfectly well
What are the basics of texturing?

Hi @a.irfan,

In Rhino 8 you can use ‘Import Material’ to create a material from an image file.

In Rhino 9 WIP you have much more control.

Thank you very much!
Could you please send the first picture in a higher quality
Some of the letters are blurry…
thanks

[martinsiegrist]

Nothing blurry here…

[alter42424]

right,
now it’s ok
The problem was probably mine

Mapping textures

Hello fellow humans, I am new to this interface. It has been suggested that I might use it to map a texture on a surface in Vray. Their wood plank is at 120cm and needs to cover many sq meters. Is this in fact possible? Also, how hard would it be to write a “live link” to the Unreal rendering engine for GH?
