since i know that denis is watching this forum i`ll ask here for a feature request. Is it possible in the BlockShaderNode to get a "column vary" in addition to the existing "row vary" parameter ?

I often need bricks for decoration or above windows to be vertical oriented, with cubic mapping its not really possible. It would be a lot easier with a column variation parameter.

Rman Collect development is stopped for years,
I just continue to support/maintain these shaders,
and looking at the code of the original "Blocks" shader
I don't think that this is possible to add a "Col Vary"
parameter, I would rather apply a Bank rotation
with cubic mapping,
...but I noticed that the "Rotation" sub panel of
this node is unactive,
so I fixed it and updated the x32 version of
RmanNodeCollect, you could try also to connect
a <0,0,90> vector in Rotation input.

Thanks for the quick reply, sad to hear that development stopped. But rotating gives sometimes weird results, maybe thats why it was locked.

The problem with rotaing the cubic map is that you have to seperate the objects by side, because when you rotate it you can have only one side with the correct pattern. Column vary could have solved this easily.

I suppose that I misunderstood your request,
looking at the image you posted in a new thread,
you would have different block height by raw,
something that is directly possible by increasing
the "Jagged" parameter in the second panel
even in the Layer Texture version, push it to 0.6,
"Raw Vary" is rather for decaling blocks lateraly,
with a random effect if you enter negative
values. Please don't blame me if these parameter
names, often copied from original Renderman shaders,
are not always explicit.

sorry, there was no misunderstanding, the other thread is a different question. and has nothing to do with the column vary. And yes, the naming is sometimes odd.
