anyone who uses sketch up will know this problem..... dodgy looking shadows on flat surfaces. if you are like me and have no clue how to make ambient occlusion maps and things like that. i found a method to sort out them pesky shadows.

here i made a simple model with a hole in the middle to show you what i mean.
on the right model with horrible shadows on the left a lovely model with no horrible shadows.

here is the same model in sketch up before exporting. To get rid of those horrible shadows all you need to do is this....
use the offset tool and make a very small border on the face of your model around the edges and around whatever is causing the shadows, like i have done on the picture above.

the off set tool is the bottom right one.. or just use the line tool, if the offset tool wont do the job.
now when you import your model into muvizu them pesky shadows should have gone. hope this helps you out. it makes your models look a whole lot better

even using this border method on a simple cube will make shadows better.

box on left...... no small borders....
box on right...... small border method
both boxes are made from the same model

Thanks for sharing!

May I suggest adding the information to the Wiki? Big Grin

Posts: 1988 		Fazz, you are a flippin' genius - I always knew you had to add extra lines to try to 'even out' the shadows, but it never worked across the whole model... Using the offset feature like this is going to change that for good - thankyou! Toast

1. Select the edge of the cylinder

2. Use the Move tool to move it up/down but with Ctrl pressed (which forces Sketchup to copy the line)

3. Move the copy of the line (constrained to up/down) and you have your seam without changing the shape.

And just to show it works, here's a door I was just working on (that didn't work right with the lights, as usual, as you can see on the left). After it's been 'Fazzed', as we should call it, it looks great - thanks again dude!

lol. i think it would involve being smothered in cheese Big Grin

on a side note.... ziggys cylinder border method also works on arches and various curved surfaces where you can get a continuous line from edge to edge. now onto cones.......................... Big Grin
