Thanks for the detailed reply, I appreciate it!
So I created a clean example project so I can share here since my project is getting very complicated (especially for me as a noob), I do many mistakes and still can't solve many simple problems.
— the reason I prefer to use the SetColor is because I have extra control with the Alpha for opacity, but if it's not possible to use it I'll be happy to use the other option.
As you can see I didn't solve the color selection in that project maybe you can help me out here.
Also, I made a OFF-TOPIC point to show that what Ashley said:
rgba takes values in the range 0-100, not 0-255. It's also fine to pass floats to these expressions - any rounding or clamping is done internally in the expression.
Is not accurate at least on the current version and I wondered why it is not fixed on the expression tip that suggest 0-100 for every color while it is obviously 0-255 for RGB and 0-100 only for Alpha, this is how I'm used to it on animation software so it's great!
File Example, as you can see I can SetColor from 0-255 for the RGB:
File Test C3
Back to the Original Issue:
I hope you can help me out with the selection, my goal is that whenever you select or add selection to an object is to set a random color but unfortunately I'm not smart enough to solve this.
Thanks ahead for any help!
