How can I put/ blend in some pixels unstretched on top of my material?

[kirkr5689]

I mean I have one material 32x2048 pixels  and want to put another one 2048x2048 on top of it ?   Is there a node that allows to do it in a simple manner like in Photoshop ?       I am tired to do my own blend nodes  which somehow  always fail  at certain  conditions.    Am I missing something ready made and  simple to use?

Can you show an image of what you want to achieve i.e. the two starting images and the result - use Photoshop if you are familiar with it. Then we can show you how to achieve similar in Designer.

  Thanks Dave for your reply.   For example I am working at a dirt edge material  64x1024 pix sized and want  to put existing  regular square asphalt  texture  on top of the edge( on the right side)  as it is in my psd.

I see I have to crop  the asphalt first to 64 wide stripe  similar to  the edge texture. But it's not easy with the default crop node  and it makes the asphalt blurrier , always re -rasterizes it.    Never perfectly 64 pix.    I see  the crop node does have some integer "inputs"  but I never been able to figure out if they do anything. Never saw any difference.

So is there any out of a box  node that could do it ?  or something just same carelessly  easy as in Photoshop?

For your use case set your maps up as shown.

In the crop node set the node output size to Absolute 64 x 1024 px.

Set the input size to 1024 x 1024

In the crop node click on Edit Matrix Values and set X1 to 16  (which is 1024/64). Leave X2 at 0 Y1 at 0 and Y2 at 1

Adjust the offset to show the strip that you want overlaid on the background

Thank you Dave.  My guess I could set up the formula for the transform matrix  that way using #size .
