I just wanted to say thankyou for the tutorial series! I have just got back into unreal after 2 years to try and make a game inspired by rainbow 6 siege and ive forgotten almost everything, i am only up to this video so far but you are very easy to follow and explain things well compared to others i have watched in the past.

@RobertBojor 6 месяцев назад

Awesome series!!! Just a quick note for those that want to use the Thread Safe anim bp way... You don't need the interface for the player, just create a "pure" function in the character BP that has the output pin name "ReturnValue" and you can easily call it from the thread-safe anim bp functions. Also make sure the "Is Not Valid" execution pin returns as well after the log print.

Using Character variable in Animation Blueprint event graph is also casting. I suggest to use "Try Get Pawn Owner".

@astralstormgamestudios1259 6 месяцев назад

Pitäis kirjoita englannin siis olen oikeesti ruotsin kielinen mutta, how did you get the upper body blend space to react when jumping with weapon? I have the transform bone and layer blend but when I jump he doesn't do anything with the upper body.. he just plays the walk/run animation.. It would be cool to make him move with the hands when jumping/landing.

@PitchforkGames 6 месяцев назад

Amazing work on this tutorial series! This works perfectly as expected on Manny, but when I apply the exact same process to a metahuman, the left hand IK doesn't follow the weapon when it moves and rotates from hand sway and recoil. The hand rotates, but the IK doesn't move with the weapon, which is weird because it moves when I adjust the LHIK socket location. Please help!

@ugurkamilboz8778 4 месяца назад

@itsdonix 5 месяцев назад

i have a custom model, and for some reason the hand has some wierd offset any idea why?

@iGunSlingeRv2 8 месяцев назад

When you set up the WeaponSocket, you then go to the character blueprint to add the weapon and then rotate the weapon there. Is there a difference if you were to rotate and position the WeaponSocket instead? Or is there a reason for this set up? Either seems correct to me but asking in case there is something I dont know lol

@voidcompiler3799 8 месяцев назад

Its better to rotate socket only. But both works.

@bengames1565 7 месяцев назад

@vitlaska 8 месяцев назад

Hey! Thank you so much for this series of tutorials, this is kino stuff! I have a question: I keep getting an error due to the "Valid" function inside that GetLeftHandedSocket, my best guess its because it doesn't get assigned a value for "transform" to return to in the case it is "not valid", yet I don't know how to solve it, due to me being shit in blueprints. This is the message: "PIE: Error: Blueprint Runtime Error: "Accessed None trying to read property BP_WeaponBase". Node: Branch Graph: IsValid Function: IF Get Left Handed Socket Transform Blueprint: BP_ThirdPersonCharacter" edit: I'm using 5.31 if by some weird functionality mix-up that was the problem, crossing my fingers its not

@vitlaska 8 месяцев назад

I think I fixed it? But I don't know if it was the correct way of doing it... The "Input Object" node of the "IS VALID" function wasn't getting anything trying to read the Weapons Base through its child component (don't know why), so I went and plugged it to the [Is Valid] function without the (target -----> child actor) node.

@voidcompiler3799 8 месяцев назад

Good you found it! I show how to do it in 3# video I think.

@toggleGDC Месяц назад

Removing that jiggling movement while walking go to Animation Blueprint -> Animation Graph -> locomotion -> idle and walk/run states, Then find Layered Blend Bone nodes and set "Mesh Space Rotation Blend" = True.

@user-oz7bv5sq4h 5 месяцев назад

I have a question. Does LHIK only work for weapons where you hold with two hands? I'm following everthing exactly as in video (also redid everything from scratch twice) but won't work with Pistol. The Pistol is from the same pack and that's the ONLY deviation from tutorial. Any help?

@voidcompiler3799 5 месяцев назад

Should work exactly same with pistol. Do you have LHIK in pistol?

@dcad6934 6 месяцев назад

Hey. The left hand IK works really well, but I have this issue when I use a different pose for putting down the weapon the left hand is no longer on the weapon but a little further down. Do you have an idea on how to fix that?

@voidcompiler3799 6 месяцев назад

I dont completely understand. But in later tutorials I show how to drop weapon and change pose to hands only. That also disables left hand IK.
