Transform>Rotation vs Stepped Rotation Effect
« on: February 16, 2023, 02:09:42 PM »
Hey there,

I am trying to scatter some objects along a line - pretty simple. I want said objects to have a random axis rotatition from -10° to 10°, which I can nicely achieve via Transform > Rotation. Problem is, that now - seen from the side - there is visible texture repetition, as the range of 20° between the min and max rotations isn't really big. To counter that, I also want my objects to be additionally turned in 90° steps, for which I use the Z_Rotate_Step effect. This one works great too, but cancles the transform rotation (-10° to 10°) set up previously.
Is there a way to combine the two, so that my object is randomly turned in the range from -10° to 10°, but also individually turned in 90° steps?

Sure, I can just save the object four times, rotate it 90°, reset its X-Form and add it four times as scattered geometry, but this is not really elegant, is it..

Ok, I assume that you have an exported parameter for rotation to which you added a random parameter -10 to 10. Just add another random parameter (integer) from 0 to 3, multiply that by 90, and add it all to the previous one from -10 to 10.
Or, just use the expression with Min and Max inputs (it should work fine):

Return
randomReal(Input1,Input2)+(randomInt(0,3)*90);

Thank you for the quick response, Dragan!
Let's see if I can manage to integrate this logic into FP.

I don`t know how this post ended in FP section. I assumed it was for RC because I'm getting notifications for RC posts.
Yes, the same logic could apply to FP, I gues you just need to edit some FP effects.

Thanks, nevertheless!
You became a notification, because I falsely first posted in the RC category. Seen positively, now I know how to do this with RC, which is great!
Still I would be happy to know how if it'S possible in FP, too. Maybe someone knows that.
All the best and thanks again!

You can do the same with Forest Effect.

Apply Forest Effect and just add +randomReal(-10,10); to the marked line.

Perfect! Worked like charm - thanks you so much!
