This is the method i have for now, the timeline is working but the post process material param is not changing and giving me a " acessed none" error. I have created a dynamic material and talked with BOTH gemini and chatgpt and both of them have been getting to a stage where after that is absolute nonsense.
this is what they have got to till now, but unable to get past this stage. everytime i reach this stage they just absolute crash and start spitting none sense like connecting the “make weightedblendable” to the “add array” which is not possible. and connecting the result of the “add array” to the “make post process setting” which is also not possible.
does anyone have a good idea on how to do this or on how to continue it?
You need to assign the created dynamic martial instance back to the post process. Just creating it is not enough.
At least that’s the flow for meshes. To be honest I’ve not tinkered enough with post process materials but there should be a way to assign/apply it through blueprints.
yeah i know what i need to do, but i just cant find a way to do it. on UE5 i found that its very easy to do it, but on UE4 its very complicated and cant figure it out
Pff… Sorry I wrote the answer without taking into account that you are on UE4. Unfortunately I don’t have UE4 and have no idea what the situation is there.
Anyway, I’ll leave it below just in case it has something useful in it for you or for someone else.
Sorry but I don’t have time to test it at the moment but it should be something similar at least.
Also I’ve put it in the Third Person Character, which is not the best place for it. You should probably think about where it should reside - in the player controller if it is part of your game-play or in the level BP if it is something specific for this particular level.
i tried your setup and added more to it because it keeps giving me “accessed none” error when trying to change the scalar param. for some reason the “fog mist” keeps returning null.
iam sure its something wrong with my casting and “creating dynamic material” but i just cant figure it out.
Unfortunately I don’t have UE4 and have no idea what the situation is there.
