I am trying to do grass and would like  densier  distribution . Is there a way to do it in same shape splatter node ?    By having unrestricted shape multiplier  probably like with fx -map?

It is clamped within the shape splatter node.

If you save a copy of the shape splatter node and open it, you can modify the processing within it to create your own modified version, but is not as simple as just unclamping the max 'Scale' input. Doing that still results in the max value of 5 still being used within the processing, so you will need to edit the functions being used by the pixel processors within the node.

Yeah, I understand it. I just couldn't  find  what math exactly  is in control of that limit.   When  I try to unclamp the scaling  factor  the things are just getting cropped  and that's all.    So to be exact I need to know  what math function and where  is in control of  that crop ?     Any why  it's limited at all ?

You can see all the functions driving the node if you copy it and open it for editing. It is complex though and uses several pixel processors, each with its own function. The scaling value is used in one the pixel processors labelled 1322881960

Not sure but it doesn't look like anyhing in that processor  fixes the crop size .   It can upscale the images themselves but they would just be cropped  off by a sort of a frame related to the number  ot grid cells .   So more scattered things you have smaller the crop  and thus  harder to reach  desirable density.

Here is what I get if just increase the size allowance.

My guess I could just make 1ike 10 splatters in sync  with height blended  result   but not sure  it would still be speedier than fx-map node ?   For some uncertain reason  after two splatters  each next one is getting more and more  slow .

I wonder is it a limitation by  design?  Nothing we could workaround?  I ask because all similar noises scattering  elongated details are still fx-maps.

The processors work together, which is why just removing the limitation on the one value does not achieve unlimited scaling. You would need to go through the graph and amend the functions across chain to create an amended version that meets your requirements. It would be a good exercise in discovering and learning how the node works.

   I see nothing related to the scale  of such frames exactly in other nodes.   Spent quite a while for this .    It's actiually the exact question I need an answer for.  What defines those frames and how to change it?
