Material flickering (default blank mat shows up periodically)

Development Rendering

Ive got my pawn mesh with 2 different material interfaces, and ive got two materials for each one. Everything looks good in editor, but when i start playing my main (0 member) material interface pereodicly sets to default white mat. Is it a bug or i have to set something specific to solve it? The only one solution that is working now for me is placing Event tick node and set materials there, each tick… im pretty sure its not right)

Hi kmskazka -

I am watching your video and it looks like your character has no material or a translucent material in Element 0 when the character is rendered correctly and it blinks to a Black material and the characters head renders incorrectly. I want to confirm that I am reading your issue correctly. Either way, Can you show me how your setting up your character’s materials? Are you setting them in Persona or through a Blueprint?

Thank You

Thank you for reply,

I’m setting materials via persona, both of them are opaque and lit.

Hi kmskazka -

Are you seeing this flicker if you view your animations in persona or is it only when you PIE? From the picture I see you are using a morph target, how are you calling that, is it setup in an animation or is it being called in the Character’s Blueprints? And finally, can I see your character’s blueprint setup?

Thank You

Hi Eric -

Thank you for the response, after checking my blueprints i found something that cause that issue. It was mine function that makes material transparent if they are above my character, i forgot to remove my char from the trace channel so it swaps his materials too) Sorry for disturbing you)
