Gradient Probability
« on: February 27, 2019, 02:37:44 PM »
I like the Gradient Probability tuturial. Is there a way  to use more than two materials ie. A range of reds changing to a range of blues along a facade for example?

Hi,

You can use the same style set-up as shown in the Graduated Colour Probabilities "Ten seconds tip" in combination with the RailClone Color maps used within the assigned material (for example, the Tint feature can be very handy for this kind of tasks).

Hope that helps.

Best regards,

Thanks Michal, I ended up with a similar set-up using Corona multimap, makes sense.

Hi there,

I am trying to use the graduated example in the Ten Second Tips in my scene, but somehow it's not working. I have a feeling it is to do with the expression. In your 10 sec tip, the expression written in blue is different from that in the screengrab below it. I have tried to use both with no luck - my tiles render black. However if I use a standard Material node without exporting any parameters the different materials show up..albeit not graduated. Please see screengrabs attached.

I'm sure it's something very simple but I can't seem to get it right.

Thanks,
Terri

Please not that expression syntax has changed a bit from V2.
Expression editor functions has been expanded. And that required some changes how they are written.

Test expression "-1*(Input/4)" in v2 should be written in v3 and v4 like this:
return -1*(Input/4);

Basically all expressions should have "return" in start of "expression" and You should end them with ";"

If You need further help with Your current style, feel free to attach a simplified max file.
