View Full Version : Grass help
Carlos 04-15-2002, 01:38 AM Hi Guys,
I am new here and into 3D graphics. I am using Max.
I am trying to texture a plane of grass for a kind of architectural picture project. I am having problems with the circled area, the arrow ones look good to me. The ground was done with a nurbs surface (points) and I applied a uvw planar map on top it. The material is a standard blinn with a tiled map. The view is from a camera with FOV of 45.
Does anybody knows how to fix this weird look?
If any knows how to do a better grass I would appreciate it too.
Thanks for the help guys.
:thumbsup:

It seems that area is simply ugly because your map isn't holding up due to it's resolution...
How big (pixel*pixel) is your grass texture? Because when texturing large areas of ground - you need to (generally) have very high res texture maps, if only to counteract the problem you have now, pixellation when close to the camera. Tiling more will give you more pixel per pixel (if you know what I mean), but it will also emphasise the repeating pattern...
Another factor is the bump level - it always looks higher when you get closer to the camera on something like this. You can rectify this by creating a blend material with the same material in the two slots, taking the bump level down in the second slot and then using a falloff which is relevant to the camera position (Toward/Away, distance blend... play around and see which one suits the scene best).
Hope this is what you were after

Thanks AJ_23,
I don't have the resolution of this file nowsince I not in my computer now but I will find out and let you know. You are right about increasing the tiling it gives a pattern.
I will try the the blending advise. I'll let you know if I get any good result.
Thank you again for your help.

Hi again AJ_23,
I got the map resolution, it is 640*433. I think is big enough.
I tried the blending option and I got a better result. I did it with a reference object because I couldn't get to work the distance blend through the z-axis of the camera. Anyways I got a better result than the original one.
By the way I wasn't using bump map.
Thank you again for your help.
