Scale or Stretch Texture on the Surface

[galiaf_velikiy]

Hi, guys. Could you please help me achieve the same scale effect as in SketchUp? The Unproportional Scale is also what I need. Thank you.

[Lingwisyer]

I think you can just use the COOR commands?

 I am already using COOR3.

COOR{3} can determine the origin of the surface, it direction and the method it is wrapped, but I am not 100% sure if it can stretch the surface.

Does it need to be done in GDL or can you just create a duplicate surface and increase the size of the texture?

Barry.

[galiaf_velikiy]

it should be a GDL, I need it for the multiple-use case.

[MetalFingerz]

@galiaf_velikiy ,

It's possible to scale a texture dynamically by having a DEFINE TEXTURE with scaling variables (and then doing a DEFINE MATERIAL with said texture) but I don't know if it's possible to extract the texture name from a REQUESTed material.

If you already know which texture you want, you could hardcode it directly maybe.

[runxel]

It's possible, even tho you must need to do some contortions.

file_name = ""
rrr = request{2}("Material_info", old, "gs_mat_texture", file_name, w, h, mask, alpha)

define texture "new" file_name, w*2, h*2, mask, alpha

tex_id = ind(TEXTURE, "new")

str_name_of_mat = ""
rrr = request("Name_of_Material", old, str_name_of_mat)

define material "new_mat" based_on str_name_of_mat,
	parameters gs_mat_texture_ind = tex_id

mat_id = ind(MATERIAL, "new_mat")


material old
brick 1,1,0.1

addx 1.3
material mat_id
brick 1,1,0.1

Don't get hurt.

I copied and pasted your script (created the "old" parameter) and got the error message, am I doing something wrong?
"Error in definition of materials used at line 21 in the 3D script of file Untitled-1.gsm."

[runxel]

Could be a GDL bug? I encounter this too, in AC 28.

However it still works. So I'm not really sure why it's nagging here.

[Victor Vernaglia]

Yes, it's working, but this error message is very annoying. Thanks for the reply.
