Placing Texture on another Texture or Material

irwanwr

hello everyone,
i found and read a post about texture that wont overlap the surface of other surface on top of it. i found it by skimming. then i forgot where it is. i've been looking for it for two days now. well, not really 48 hours.

the post was about putting a picture, image or texture on a surface of another component or group entity. the texture is not overlapped and stay clear without disturbance of the surface below it.

the last reply of the post was made by Gaieus if i am not mistaken. he put a picture of two person as a texture on a surface of a box with brick material or texture.

Gaieus

This happens if you place a picture on a face (or group/component) as an image entity. Import the picture as image and do not explode it. I do not know how it renders in external renderers but in SU, they somehow solved the Z-fighting with this (some time during version 7 as far as I remember).

could you explain what "the Z-fighting" is?

Gaieus

It refers to a conflict in the "depth" direction between two faces (if we speak of SU) that are on the same plane. Make two 2D shapes on the ground plane, paint them with different materials, group them separately and move onto each other to see what happens.

In 2D applications you generally have something to "bring to front" or "send to back" but since we are in 3D here, space should do it. Unless we are using tricks to make life easier.

thank you for the explanation Gaieus.
i worked for advertising & printing shops before.
used to work with only 2D applications.
i'll try to learn and understand more on that matter.

Hi folks.

Try this:

1 - Import the image.

2 - Explode it and then create immediately a component with it.

3 - Set its gluing on face property to "Any".

4 - Set it to automatically cut openings.

This will result in a component that will automatically cut an openening in any face, thus eliminating the moiré effect caused by Z-Figthing. Other benefits are that you can move the image around on the surface and the openening will follow and also, if you delete the image component, the surface will heal itself.

Just ideas.

thank you very much, Jean.
