Damn dude, i came to your tutorial from the indie game developer post you posted recently and you have no idea how much this helps me in my upcoming horror game..i will definitely mention you in the game credits thanks!!! :)

[@underscore00]

Thanks so much! That would be awesome man, glad I could help :)

[@solidgamer9569]

subscribed and will check out all of your tutorials, you're REALLY good and deserve many more followers will spread the word around if someone is looking for UE4 tuts.

[@underscore00]

That's so nice :) You absolute legend!

[@solidgamer9569]

do you have a paypal? kindly send it to me id like to share some good vibes.

[@underscore00]

Sure do! www.paypal.me/JBunderscore Much appreciated :)

Some shortcuts he is using: S + Left click = Create parameter node 1 + Left click = Create number node 3 + Left click = Create color node M + Left click = Create multiplication node D + Left click = Create divide node

[@thotchocolate9042]

Man none of them even work for me, so weird...

[@TheF4c3m4n]

I needed to find a way to do the thermal vision on a Post Process Setup I have installed and I came across this! Wow, and I am already subscribed to this channel?! I followed alongside Underscore and many of the UE4 Dev Community and produced some Amazing results. Thanks a Million! Anyone who wants some very awesome variations on the look should try using different Noise Masks as I tried out a few and was blown away by what I came up with. Thanks for a Quality Tutorial once again!

[@RPMonkey]

Awesome! Finally a thermal vision tutorial that doesn't require the ambient occlusions of each model or pre-made heat map textures and isn't over 30 minutes long!!!

[@underscore00]

Thanks! I noticed that there isn't a lot of thermal vision tutorials out there, and what is out there is just way too complicated and messy. This is all done in one simple post-process material :)

[@stepgames7698]

Really cool! It worked perfectly for my gunship camera!

[@MZONE3D]

Absolutely fantastic video thanks for sharing... I was playing a game called "The Observer" they have a cyberpunk style investigation mode that seems to hide/unhide a mesh within the environment that has emissive materials assigned. A breakdown tutorial of that would be amazing

[@SDCCwinner]

Many thumbs up!! Very helpful, thank you :)

[@NateIorg]

This is great, thanks for going so in-depth with it all! Quick question, any idea how you'd extend this functionality to particles as well? Such as, gunfire emitters, projectile trails, explosions, etc? That's the only spot I'm hung up on presently. Rest is dialed in pretty well with your tutorial's guidance.

[@veilight4444]

Awesome vid, ty

[@accesstheanimus]

This was amazing, thanks a tonne for sharing it

[@underscore00]

Youre welcome! This is one of my favorites :)

[@amigoface]

very cool ! now i am ready to make my splinter cell game :p

[@cannibalfish2429]

The audio sounds amazing

[@daveyhu]

Thank you so much!

[@koaku7774]

I love this so helpful however! Feedback if possible im not well versed in the material editor! if you could explain the nodes and what they do that would be a massive help!

[@samson2342]

Shit, its exactly what i was looking for, you sir got a another subscription! Thanks soo much! :)

[@RtxRob]

This is awesome, Thank you. I have one question though, how to detect fire and lights in thermal vision ?

[@vaanidel2117]

I know this is pretty old, but this is by far the best looking thermal tutorial for UE4. Do you think you could revisit this and use a texture gradient for the colors (from blue/purple cold on left, to red hot on the right)?

[@yorl418]

Hi ! Very good tutorial but do you know how to add the noise and the low res at the same time ?

[@escorpianoyqueee]

I was expecting a harder solution, like swap all textures from all objects XD, this is super easy, thanks god I checked around first

[@RetroPixelDigital]

Any idea how to get it to work for projectiles? I checked 'render custom depth pass' on the mesh for the projectile (from the third person example), but it doesn't show up in this mode...

[@acewarlock8524]

hello just came across your video good job with this did another way which was too complicated so used yours instead haha, I have a question how do you disable other buttons say night vision whilst using thermal vision thanks (late i know

[@Nightmist]

how do you get that background in material editor mine is black im 4.17.2 and 4.18 just crashes on my pc

[@masonclark352]

How do I get a noise mask it’s not showing up

[@furrybproductions]

How can I make this so that the characters are visible behind walls like in heat vision?

[@chikabestwaifu1539]

Very nice video! Still works for UE5! Somehow my thermals only do the Thermal params once per play. Must have done something wrong...

[@AssassinGrudge]

is it possible to use temprature ?

[@enragedgamersco]

This is really great! Is there a way to see through walls though? I'd like to be able to see players through thin walls if possible in my game.

[@enragedgamersco]

I'd also like to ask about how to get particles to use custom depth as well. They seem to not be affected by the post process

[@unrealengineruseng9583]

Wow !)

[@OliverGardens]

And how would you make a more accurate thermal camera as far as temperatures? In this example I see this as only a hot/cold thermal camera. You enable the custom depth and it sets it to hot, but no temperature reference per object. For example, what if you had a human subject wearing a jacket, the jacket on a real IR camera would measure maybe less than 30 celcius whereas the face would be 37 celcius?

[@elbozomemelive9891]

i want to create a thermal scope but i doesnt work because you are using a post process so i create a different material that almost same but making a night vision scope

[@QuickSnipe777]

Hey there, great video! I had a problem at around roughly the 6:00 mark when you select your character to have the custom depth pass to turn him into the orange/yellow colors. I get the same result however there is a constant intense flickering going on. Would you know why this is happening? Thanks!

[@underscore00]

Hi! Thanks for watching and I'm glad you're enjoying it :) the flickering is odd, sounds like could be tonemapping. In your material, find an option for Blendable Location and test some other options. If you still run into the same issue, feel free to hit me back and I'll do my best to help :)

[@QuickSnipe777]

@@underscore00 Thank you so much for the fast reply! I’ll take a look and let you know. Also, is there a way I can add volumetric clouds or something after so I can have black/white clouds visible in my scene. (For context Im trying to make an infrared scene). I tried doing the sky mask like in the video but I just got a solid color in the sky instead

[@32zim32]

Not working. After steps 3:36 it starts to show only solid green color. No matter what I try.

[@PikBo100]

on UE5.2 is not working (( i enabled the Custom Depth on my character but is still blue like other objects ((

[@paleavenger3645]

hi great video - everytime i try to apply this effect to other objects it just makes the whole scene thermal. What am i missing??

[@underscore00]

Sounds like theres a problem with your custom depth mask, which I set up at around 5:15. Double check everything there and let me know if it keeps happening!

[@paleavenger3645]

yup that was it, check the custom depth and make sure the post process does not default to enabled. Thanks!!!

[@underscore00]

You're welcome! Thanks for watching :)

[@eduardoandreotto3504]

This method can work on Android?

[@jayvergara8146]

Particle system not visible

[@thotchocolate9042]

Gotta see how to wrangle this effect on particle emitters, they're currently invisible using this +0+

[@JosiahIronclad]

"welcome back boys and girls" definitely not creepy at all.

[@gordonbeeman5387]

Imagine downloading Fortnite updates slower than Epic Games makes them...

[@RegenerationOfficial]

stop that shortcut nonsens...

[@JohnDoe-yc6nm]

yeah makes it really hard to follow
