Scale by RGB

Hi all, I want to ask regarding this effect

This effect is achieved using scaleScript, my question is if it's possible without script.

From what I see, it seems that standard tyflow is already almost there, or maybe even achievable already but I am not sure because I didn't do extensive testing. The scale operator already has the option to multiply by textmap, it does indeed drive the scaling according to the value, but it's applied uniformly to all axis, making some of them fatter than the other, when it should only be driving the z scale.

Is it already achievable? From my few minutes testing it seems that it's already almost there, but alas I can't just scale the Z axis. If not, maybe this post can double as feature request to be able to use texmap to drive scaling in only 1 axis, 2 axis, or all 3 axis.

Sure, that's possible. Scale by texmap is just a multiplier on whatever values you set in the main spinners...which themselves can be used as multipliers on a prior scale value.

So you can setup one scale operator to define your base scale, then a second one with scale by texmap to act as a multiplier on it. Set both to continuous if your texmap/scale is animated.

Attached is an example file. Change the scale of the first scale operator and see how the second one simply modifies it with a tex.

Thanks for the reply! I downloaded and opened the scene file, but i think the effect I'm going for is a little bit different. Your example file, the smaller cubes are actually smaller in x and y scaling as well. What I am going for is to have uniform scale value on the x and y of all the particles, but only z axis is driven by the texmap. Right now, they are quite varied in 3 axis.

Oh whoops, you're right.

I'll add X/Y/Z multipliers for the scale by texmap in the next build, so you can control the influence explicitly.

Awesome! Thanks a bunch. Can't wait for it. Also thanks for building this awesome tool.
