Painting Mesh ?
-
Does anyone have any experience in painting a texture onto a mesh created in sketchup ? Could this be done in photoshop with a tablet ? I often have problems texturing landscapes, even large maps tile and google earth images are not good enough. I'd love to be able to use textures with brushes.

Hi Simon, I suggest you take your lead from the gaming industry. produce a set of integrated textures; that is...a basic seamless grass, the same grass with scattered leaves, the same grass with denser leaves, or bare/muddy/stony patches.
Same again for stony or paved areas.
Obviously, SU can't layer these textures like some other programs or games can, however you can paint directly onto the triangulations or use Tools on Surface to mark out irregular patches which you can paint with all the variations. That gives you complete flexibility as to what goes where.
A very quick example looks like this.

It's pretty straight forward once you unwrapped the UVs.

Alan that's close but i don't want to paint triangles. Richard can you explain more ? Many thanks.

Unwrap your terrain in whatever unwrapping app you like.
Export the UV Map.
Edit in Photoshop using various seamless textures and blending styles.
Create spec, norm and disp maps from the diffuse at high and lo res
Use lo res in SU and high res for rendering
For added jazz bake an ao map to overlay the diffuse to enhance the details.

Interesting thread. Thanks!
I wish there were some monthly periodical which would run an article showing these steps with examples, specifically in relation to SU. I wonder if that could ever happen

In SketchUp, you can use the Paint Brush from Artisan.

It's good Alan but is restricted to painting on whole triangles. I am investigating 3d painting in photoshop i believe it can be done.

I realise that, Simon. yes, it certainly can be done. Just make sure you have enough construction geometry drawn onto the terrain before unwrapping it...otherwise it's going to be pretty featureless and difficult to judge what to paint where on the map.
