Floating objects after applying material during render

[samo8076]

hi guys, iv placed a grass material on a sandbox, all looks good until i render. it seems to push the sandbox down/or the rest of the objects up level with the length of the grass...any ideas why this is happening?

im not too sure exactly what your trying to do...

but i will work on this premise. You want displacement on your grass and a concrete paver amoungst the blades coming through.

Firstly its just my opinion but displacement on grass this close up dosent really work, id use PS and feather some blade of grass with a brush, but anyway on with your problem.

It looks as though your paver is the thinkness of paper, so id extrude it through the terrain by a 1m, but only have 50mm showing above the surface. Now render, and if the grass appears above the slab too much... lower the terrain or raise the slab until you have the desired effect.

Hope it helps

Kind Regards

Re: Floating objects after applying material during render

if it is a concrete step on the grass what you're tryin to achieve, why don't you just extrude the concrete down?

the grass is meant to sit level with the edge of the building and the concrete block is meant to sit on the grass...i think iv sorted it after hours of playing with the sittings, i turned off Allow 2 Sided in the displacement option and that seems to help a lot.

Re: Floating objects after applying material during render

We have an option called "Shift" on the Material's displacement option. This option allow you to move up and down the displacement geometry. If you use negative number you will shift down the displacement and if you use positive numbers you will shift up the displacement.
In your case, you have to use negative number to move the displacement down. It is very important to disable the "Use Global" option in oder to be able to use the options per materials.
