in the docs it's written that Partition attributes can only be integer or strings . but i got the same results when partition attribute is float or vector ?? in for each node .


so my point is am i crazy or does the line - “Partition attributes can only be integer or strings” do actually true in other workflow cases ?



-thankYou

1.what's the difference b/w iteration 0 and 1(in block end node) ?

{
1.(a).gather mode set to “feedback each iteration” and iteration set to “0”{in the block begin node} then how come it's showing results of the node b/w block end and block begin 1-times(single times) ? my point is how the iteration is working ?

>>>maybe i'm thinking differently(and houdini is working differently) that's why i'm confused so plz help me clear the confusion .


{i'm wondering the answer –>>it's happening so because when the method is set to “fetch feedback” the node’s input is used as the output for the first iteration ?? plz tell me whether the answer of my own is right or wrong.}

}

2.what's the point of having fetch input option under method menu inside block begin node ?










-thankYou.
( i'm indian that's why my writing is not concise plus at my school i never wrote so much like this. so apologise from me and thank you for reading my thread and clearing my doubt,i'm very new to 3d plus i don't have any physical tutor, so it's community who are everything for me.)

1. attribute is ‘marked transforming’ if it's type info or qualifier is set to one of the transforming types as mentioned (Position, Notmal, Vector, Quaternion, Transform Matrix)
you can set those using for example Attribute Create SOP, attribtypeinfo() VEX function, Add Attribute VOP, …

2. transformed means the transform matrix will get applied correspondingly to the type info, so Position attributes will be fully transformed, Vector just rotated+scaled, Quaternion just rotated, …
so yes, it modifies the values of such attributes which for Position attributes can be also thought as changing the location

3. what do you mean by attribute transform? Transform by Attribute SOP? if so then yes, it's the same as Attributes to Transform parameter in that SOP, or in Deformation Wrangle SOP, Bend SOP, Point Deform SOP, or Other Attributes in Bone Deform SOP, …

4. to have all relevant attributes correctly transformed, not just P
