Export 3ds texture

[ecati]

I drew a model like this and applied snake texture with TruePaint.

When I export as 3ds, fbx or obj, each rectangle and triangle textures are located separately. Therefore, the file size is growing very large.

When exporting in these formats, is there any way to export as a single texture?

Export as DAE

export as OBJ

Texture was added with TruePaint, both exports from SketchUp Make 2017

export as 3DS from SU2020

Thank you for your reply but I don’t understand properly, what must I do?

On your model I get the same result, with the texture divided into many small files.
But if I redesigned your model, starting with a Circle > PushPull > Divide > Vertex Tools > TruePaint, the texture is exported in a single file.

Something like this:

OK. But the whole model is like this. It takes a lot of effort to do it with your method. Is it not possible to quickly transform the model?

• export as OBJ, but without texture

• import OBJ file in Blender and add texture by Open image, then Export as OBJ
  
  
• import that new OBJ file in SketchUp and then you could export as DAE, 3DS, etc with one file texture

Although there are some erroneous textures, it can be considered a solution. But can’t it be done without the need for other programs (like blender)?
If Sketchup is insufficient, why is it true to try to model with Sketchup?
Perhaps, experts in textures, I think that they can make similar models with Sketchup without the need for other programs. What do you think?

I want to change the question.
When applying a texture to the model in the picture and exporting 3ds, a single texture is exported.

If TruePaint is applied, multiple textures are exported.

What is the reason and is there a solution?

I learned that, Sketchup does not support perspective textures, only parallel textures.

Sketchup generates too many textures

No, SketchUp does support perspectivic texture transformation (4 texture pins freely placed) and internally keeps a single texture. But under some circumstances, namely export, it assumes the export format supports only affine texture transformation (3 texture pins freely placed, 4 texture pins always form a diamond). Then SketchUp makes textures on faces with perspectivic transformation unique. You could keep discipline and avoid perspectivic transformation altogether (use only red, green, b…
