Hye,
After some research, I found that “Random” is with the Kismet Math Library. But I don’t know how to add it, the answer is anywhere…
Thanks.
Random what?
Random int Random float Random vector…

Are you talking blueprint or C?
" I can’t find Random function on blueprint"
Blueprint ^^
Right mouse button on blueprint main screen. Search box will appear - type random
And visit the learn site, its great.

Yeah I know, but I can’t find it with the right click
Where are you? What kind of actor are you in? I notice it only says things about particles…
In a material
I would like to put a random noise texture with a random vector
You’re confusing me…
“Right mouse button on blueprint main screen. Search box will appear - type random

And now “Epic Developer Community”
Everything you need is there.
Right you wont find them in there… 
That’s not a blueprint, it’s a material.
What are you trying to do?

You can put random noise in, just look for the textures in the content browser. What do you want to do with the vector?
Indeed… ^^’
I would like to get a random vector to put it in a noise texture. The texture is going to be change a bit, combine with a vertexNormalWS and put into world displacement (on my world material).
The material is on a spheric mesh.
That’s because I want to create 1 unique world for each game. So I need a random noise in order to displace my sphere every games ^^
The random noise is all you need to displace your mesh. You do have vectors in materials, but they don’t work like vectors in blueprint.
I think the problem is that a bumpy mesh, is a bumpy mesh. It’s not really a different world.
If you randomly chose to show them a ball or cube or pyramid etc. That would be different…
EDIT: Sorry. Tell me if you can’t get it working and I’ll take a look.
