What do you mean?
- modify the texture of the materials of the relatrive tiles to the internal wall/floor layers?
- create in the wall/floor a "strate" of tiles, to which to assign its own material (texture)?
- or what else...
I was very vague and imprecise. I hope I'm clearer.
In summary I have to create a floor whose surface consists of tiles 30 for 60 anthracite colors. .
I have difficulty setting the size of the individual tiles and creating the escapes also do not look like creating a material suitable for my needs.
with regard to the graphics, relative to the various views, from the properties of the material assigned to the "floor" you have to appease a plot (retino) that reproduces the dimensions (or fugues) of the tiles, to be set in the layer "of hair" of the floor, or in the layer "inside" of the wall.
As for rendering, you have to apply a texture to the same material that reproduces the effect you need.
if it does not exist in the list of default rendering materials, you can operate by:
- the duplication of a rendering material with contextual modification of the various parameters available to have "your floor"
or
-import a texture (e.g. from the autodesk site or other websites on the web) and assign it to the specific material.
in the roberto tutorial (complete) are visible the management commands of the specific graphics and rendering of each material.
