How do i show vertices?!

I imported a house from Sketch-up 8 pro, and got all the textures loaded, but the problem is on walls with the same texture, you can’t tell where the corners are. They run together, Can i show the vertices somehow? Ive tried the toony basic outline shader but it doesnt work.

Yea sorry, I meant to say I imported it into unity. But thank you, I’ll have a look at the sharp corners with maya
