Re: Noise Texture with time node
basically anything you connect to a time node that uses the raw time value into an output, (ie not taking the sine of time or some other bound limited function) will start to look like crap very quickly. Due to how the time node's value increases without bound. before you ask, udk's panner and rotator nodes have the… -
Noise Texture with time node
Hi there, This my fisrt post here so I'll introduce my self :) My name is Charles Greivelding, I'm working in the game industry for almost 3 years now. I'm posting here because I need some technical help on UDK. I'm trying to add variation to a TIME node combined with a noise Texture. But the result is really bad as you… -
Re: Noise Texture with time node
i think i see what you're trying to accomplish - you want to add some randomness into your time function so that it doesnt just go up linearly? if so then i dont think there's any way of doing that with a texture. time is just a single value and a texture is a 2d map of values. try combining other types of inputs with your… -
Re: Noise Texture with time node
No it's not about the flow map. I've got my flow map. Everything works fine except that pop up when my layer intersect each other. I want to offset the time with a noise texture like they did for portal 2 to avoid the popping. My problem is that I don't know how to use a texture as a time input. For now I'm using a time… -
Re: Noise Texture with time node
right - i've had a look through the portal2 document and i think i see what you want to do - add the noise texture to the time node then plug into a sin. then use the output of that to control the uvs of the flow map. the flow map can only distort the uvs so far before they become stretched so they have to pop back to the… -
Re: Noise Texture with time node
You could use the same basis of the transition or dissolve method to achieve what you want. http://udkc.info/index.php?title=Tutorials:Dissolve_Material_Effect The original use of this effect is for a dissolve effect, but if you mix around stuff (instead of fading to black/white, you fade it into another texture) you… -
Re: Noise Texture with time node
Thank you all of you for your help. For now I didn't really get what I wanted but I think i'm close. Here it is : [ame]www.youtube.com/watch?v=mMDSEN_PAns[/ame] -
Re: Noise Texture with time node
Yeah, what Vailias said. You'll need something like Sine, Cosine (even Frac, depending on what you're going for). Otherwise after a short while you're multiplying by 100, 200, 1000, etc, instead of the desired 0-1 (or -1 to 1). -
Re: Noise Texture with time node
In fact I want to offset the time by a noise texture. As you said time is linear that is a fact that I don't want to change but I'm sure it's possible to offset the time like this exemple : http://www.chrisalbeluhn.com/UDK_Mesh_Paint_Tutorial.html. As you can see the time is multiply by a vertex color for offsetting the… -
Re: Noise Texture with time node
you will need more than a greyscale for a flowmap since you want to offset on both x and y axis on the texture. check out this thread http://www.polycount.com/forum/showthread.php?t=91566 lots of discussion on valves flow maps and how to create the map it;s self and the shader in udk.
