Take a look at the shadows in the grass, why is that happening?

This is WIP so any comments and critics are really welcome.

can you guys see the pic?

I can see and i dunno, it looks ok to me. i mean, i dont see whats happening, except that it seem that there are more shadows than it should be?

What do you think there is wrong with the shadows niksoftarg, the shadows look a little hard but apart from that i cant see whats up?

[olivierfR]

hey...
now i see...

i think he mean the large dark triangles on the grass...
is your grass disp is apllied on a mesh which do not have coplanar polygons ? then maybe try meshsmooth before putting your displacement ...
otherwise no clue!

....otherwise strange architecture...

I had the same problem with Archicad en disp.
So I think that your"grass-plane" is not made in Max. Just delete it and make a new "Max-plane"

[olivierfR]

... or maybe you have a plane ( with tree mapping on it ) that is out of the view...well you don't see it.. and he don't have "affect shadow" ON ????
maybe

hey guys thanks for the replys, those shadows in the grass should not be there, I am using a extruded shape is not exactly a rectangle so that´s were the problem begins , the Meshsmooth is a great tip I hear of that somewhere I forgot thanks a lot everybody.

Are you using planar mapping? Use box mapping it gets rid of the problem.
