Nice ... how many cores to do that in 90s?

Thanks. This was with 12 cores, but it scales pretty much linearly. Half the cores, double the time. Double the cores, halve the time. You don't have to use all available cores, of course.

Just thought I would chuck in this render from a new engine under development. Took approx 90s. No post-processing at all, except for having to crop it down slightly to 1600x860 so it can be uploaded to this site.

Thankyou so much Gaieus - that little tip on face direction has solved my problem. All working now.

Hi,
I am 99% sure I am missing something very obvious, but I can't see what I'm doing wrong. What I want is to create a plane with a texture on it, and export that model as either 3DS or OBJ. I am using Sketchup Pro v8. When I do the export, no image is being exported, and the .mtl file when doing OBJ export is not trying to reference one either.

Here's what I did in a new drawing:

• Draw out a square
• Material paint, create a new material
• Set the image of the material to a 300x300 JPG I have on my disk.
• Paint the square. This appears correctly in SU.
• File Export 3D, chose 3DS, ensure 'Export texture maps' is checked.
  I then get a message box saying 1 face, 1 camera & 1 material have been processed, resulting in 2 triangles 1 camera & 1 material in 3DS. Note - no image.

If I look in the folder where the exported 3DS file was put, there is no image there. If I import the 3DS file into another package, no image is found on the material. If I import it back into SU, the square I drew only has the default material on it - my original one was not preserved.

Outputting to OBJ produces similar results.

If instead of my on texture, I use, say, one of the materials from Carpet & Textiles, then I get similar results. I.e. no image being written out.

If, however, I download a SKP file from the 3D warehouse that has textured surfaces in it, and export that (e.g. the Ando church model), I do get the expected texture files created that are linked to the 3DS/OBJ file correctly.

If I save my model out to SKP, and reload it, it also comes in correctly - my image appears on the plane.

So I must be missing something obvious that is preventing the material from being exported. Any clues?
