Add Material to an object

Hello,

In Ray Test blend file i've realized that there is a mesh->plane obj created with an image named decal as texture. The result is the yellow dot created on mouse click shown in the picture below:


I've tried to do the same thing on a new example but the result is that the plae obj i create remains as a square and not like a dot. Why is that?

Unfortunately, there are no images in your message.
Can you provide more info on how you created the plane object? Does it have textures when you "Fast Preview" this object?

I'm attaching the two photos again so you can see the difference. Picture 1 is the normal one from RayTest example. Picture 2 is my example from a new blend file.

What im doing is:
1) Add->Mesh->Plane
2)Add new Material -> Add Texture in Material Created
3) Add picture to the thexture
4)Scale the plane obj to another smaller size.

The result should be a yellow spot like the picture 1 but it returns a square like in picture 2.

Thank you

Please, attach the blend-file.
I think, there is something with material transparency options setup.

Hello Evgeny and thanks for your time. Finally the mistake was mine, i was using wrong picture for the texture. I changed it to .png and works fine!

Thank you

Glad to hear, that everything is fine. Good luck with your project.
