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.

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?

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

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.

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.
