Export single face to a 2D image at set resolution ?

blaar75

Hi

I am curious, is there a way / plugin to export a single face to a 2D image with the 2D image set to a certain resolution without any borders.

Here is what I want to accomplish.

I saw a tutorial showing how artists use sketchup lines exported to Photoshop to use it in different layers to create effects such as shadows, diffuse, grime etc.

Example here :
http://www.sketchupartists.org/tutorials/sketchup-and-photoshop/art-of-sketchup-texture-workflow/

So what I want to try and do, is use the above tutorials and paint on my UV maps. I was thinking that I can export the UV map as a blank texture with only the lines of the faces showing on the map. Then I create a square face in SU and import the image created by the 3D app and apply it to the face. After importing I can then trace the UV lines on the face, effectively creating faces on the face. When I am done I can then apply a sketchup line style in order to simulate what is being done in the above tutorials.

The only catch is the images exported from sketchup must be the same resolution as the UV maps, else when the map is applied it will not fit.

Initially I thought that I could just export the 2D image as I always did and then just cut and past the part I want. The problem is that it is not 100% accurate and some lines seems to be always off by a certain amount.

Which brings me to my initial question.

Is there a way to export the face to a set resolution without any borders. The exported image must be the exact same size as the imported UV map image without any borders etc.

Hope my explanation is good enough.

Thanks for any help.

Hi,

I must admit I am not 100% sure what is it that you want...even though you tried your best at explaining, but I will see if I can help.

Here is a video of Tgi3D using its Smart Texturing Tool...

This tool will allow you to set the resolution size of a single face and multiple faces as well if you want.

I think you can set the new texture created to have lines of faces turned on or off to be used as reference (This is good if UV Texture is used in more than one face). In the video the texture was opened in GIMP but Photoshop can be used as well.

I hope this was kinda what you were looking for...One thing to note is the plugin has a free version and if you like it there is a premium one with more to it.

Cheers!

Also you can try this...

Select Face
Right Click it
Make Unique Texture
Set Resolution Size
Select Pain Bucket Tool
Select Sample Paint (Color or Material Picker)
Select Edit Tab in Material Window
Click Edit Texture Material in External Editor

Note : Make sure you set Photoshop to be used for this;

Click Windows Menu
Then Preference
Then on window that opened click "Applications"
Choose Default Image Editor
Find Photoshop

Thank you for the replies.

I thought I was a bit unclear as what I want to do. Maybe my intended work flow will help to better understand.

Create 3D model in Sketchup
Unwrap / Uv map model in Wings 3D. I know, I know, There are other better ones but I find Blender very intimidating.
Export the UV. map as a image to be "painted" on.
Import the Uv map image into sketchup and a apply to a square face.
Trace the face lines (shells) of each part using SU's line tool.
Apply the desired line style.
Export the face with all the lines to a new image but this image must be the same size as the original UV map image.

To be honest I am not even sure what line style was used in SU to create the grime / dirt layer.

I will try your suggestions and post again if needed.

Thanks once again.
