Layer Sop

[sanostol]

the helpcard about this sop says me:

Each of the default attributes (i.e. "Cd", "uv", etc) gets renamed according to the current layer. For layer 1 they have their base names. For every other layer, the current layer number is appended.

but I think I have some problems understanding the correct use. I a grid gets uvs with a uv texture sop, than I add a layer ( number 2) and added a texture sop again ( with different scaling to see ) after this I want to apply a color to the points with this expression:

pic("/img/img1/gradient", $MAPU, $MAPV, D_CR)

but why doe houdini pick up the current layer for MAPU and V instead of the base layer, or what do I have to do to get access to multiple layer attributes including the baselayer in one sop. I thought that the new coodinates would be called $MAPU1

the clue is in the help

For every other layer, the current layer number is appended

So you have to use $MAPU2 and $MAPV2 to access layer 2.

If you open a spreedsheet you should see all the attributes with the numbers for layers appended.

The only other thing is that layer one is still $MAPU and not $MAPU1

I thought the layer order is :

base layer

layer 1

layer 2

instead it goes like this:

layer 1 ( = baselayer)

layer 2

dam, I have to use the spreadsheet a lot.
