Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Pulsing/ Chaser Emissive Material

Hello, I don't suppose anyone could tell me how I would go about recreating a material to pulse like how I have done in this blender animation? More soo focused on the white stripped lighting instead of the circles.

Thanks,

ooor, you can just be a liiiitle bit more patient. (No really, be more patient!)

There are multiple ways of doing this. some are harder than others. You could give each of the horizontal lines its own material instance with a variable that increases the emissive output. To give you an idea: alt text

Save this material, then rightclick on it, and make 3 material instances. Then in those instances change the "Glowtime" parameter untill you get something like this: alt text

(In this case, the first MatInstance had 0.5, the second had 0.3, and the third had 0.1) And apply the right material instance on each line-mesh to get the result you want.

If you want more control on the speed, you can put a multiply between the time and add node. this way you can slow down and speed up the pulse.

There are also others way doing it (blueprint, matinee) but I dont have enough experience with both to showcase those)

Sorry!! I get a smidge inpatient when working on something and desperate to find a solution.

Thanks you very very much Luos.

Man, I've been looking for this kind of thing for ages, A question though, is something similar timing possible with point lights though a blueprint or a matinee? I remember when I was working on the TARDIS in UE3 and I could never quite figure out how to get the lights and material timed up properly. (here is a video of said TARDIS in UE3 for those interested: https://www.youtube.com/watch?v=U4crYpUPwcM )

Hey Luos . . I have stumbled across a similar problem. . but i want it on a single mesh pulsing either from top to bottom or from left to right . .

How did you get the 'thing' called GLOW TIME?? I put a Constant there (Only way i know to make a 'number')??? But changing it doesn't really seem to make the blinking change much????

Thank you.

Way to necro a thread.

Glowtime is just a scalar variable. Hold down "s" on the keyboard and left mouseclick. (in the material editor) this will give you a variable scalar you can name yourself. e.g. glowtime.

I was just trying to solve this problem myself, and I think I might have found a great solution that is very flexible. I can also alter the speed, depth, and color of the pulse using a Vector Parameter and two scalar parameters. I can make the lights flicker or slowly pulse, and even remain black for a period of time. Hopefully this image is all self explanatory.

Good evening and thank you for the quick and easy solution. I have replicated this method this afternoon with success. However the project crashed and the material was apparently ghosted (there in the preview, but the file nowhere to be seen later). And when I have tried to replicate it again, the Time node seems to be doing some really, really weird sh*t... Such as dipping under 0. Any clue on what could have happend?
