Beer glass scene creation
This course contains a little bit of everything with modeling, UVing, texturing and dynamics in Maya, as well as compositing multilayered EXR's in Photoshop.

Questions about this render
few questions:
Lightning: I've turned off the basic lightning and used final gather with 200 rays and the enviroment color is light blue, why is it still overlit (the tower and ground for example). Is there something like a standard config to simulate daylight?
Textures: Some textures look like they get deformed, like the bricks and roof from the small house, how can i fix this?
Dirtmaps: Is there an easy way to create dirtmaps, like with the filters in photoshop or something?
Paint effects(trees): to render in mental ray paint effects must be converted to polys and take ages to render. Is there a solution for this?

I simply download some pictures of dirty brick or concrete walls, stones, etc (Myang's free textures is an excellent resource for this). I take the photos into Photoshop and crop them, then convert them to black and white images. I've found that when applied to, say, a brick wall texture in Maya, they give an excellent natural dirty look to the wall, making it look instantly more realistic.
To fix the deforming textures on the roof you need to try planar mapping the surfaces. This is under Edit Ploygons --> Texture --> Planar mapping. Just adjust the manipulator to your liking, or until it looks correct. You could also UV map the roof/wall, then put the UV map into Photoshop and paint the texture using the map for a guide. You can get more info about UV mapping and texturing from the Maya help files or www.learning-maya.com.
I've tried using Final Gather, and it can produce amazing results. Just by playing around with the values you can get pretty varied results. To reduce rendering time when it comes to the paint effects tree which is converted to Polygons, try reducing the tree's poly count, as it is probably sky high! Alternatively, render a paint effects tree out normally, then map it onto a plane in the foreground, or comp it in afterwards. This way you don't need to have the actual geometry in the scene.
Hope some of this helps. Your doing a good job tho, keep going!

one question though, how does that mapping on a plane work?
and will the tree still cast shadows in this way?
