bump maping

Complex UV Layout in Maya

Over the last couple of years UV layout in Maya has changed for the better. In this course we're going to be taking a look at some of those changes as we UV map an entire character

I am making a Black & white globe. I have mapped the texture to the poly globe. I would like bit of roughness on the surface. I embossed my texture in PS so all the continents do look raised above sea level but inside the continents everythin is flat. I would like some unevenness in the surface.

II- My sea is dark grey and the continents are light grey. Is there any way I can make the continents chrome without pysically modeling the continents????

Try adding a layer of b/w noise.

You can make a specular map. It's just like the bump map in how it works: white areas has spec, black doesn't.

grrr I am rendering another part of this animation and at the same time trying this bum I mean bump maping stuff :-)
So everything is slow. I will try what you said afterwards
Mr mtEverest ...(mtmckinleys knowledge is high and wide as Mt Everest hence the nickname:-)

Anyway I am very confused. I have a poly sphere. On that I have mapped earth texture. In the texture image the continents are blackish and the oceans are whiteish.
Then I placed the same earth image as a bump map.
When I render... the earth comes out awesome . All raised up nice topology etc. My only problem is that the the continents come out blackish but depressed rather than raised. How do I rectify it?
Do I need to inverse the colour of the texture and bump map image or just inverse the bump map image?
Enlighten me.

grrrr

Just inverse the bump map colors and save as a new file. Then, use that as your bump map.

yep worked ...1st time I tried I used inverse in Photoshop. The difference between dark and light was not pronounced enough. So i added more contrast and now it came perfect :-)

When this animation rendering stops I will try what Everest suggested :-)

grrrr
