I am trying to follow this guide A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums to create textures and run time.
The idea is to have the user draw something on a tablet and be able to save it, but I get stuck at trying to make the texture dynamic.
There is honestly not a lot of code https://github.com/Togtja/UE4Bug just 1 class with combined 100ish lines
but the issue happens at
mDynamicTexture->UpdateTextureRegions((int32)0, (uint32)1, mUpdateTextureRegion, mDataSqrtSize, (uint32)4, mDynamicColors, false);
It causes the editor to crash with error message
Assertion failed: Callable [File:D:\Build\++UE4\Sync\Engine\Source\Runtime\Core\Public\Templates/Function.h] [Line: 608] Attempting to call an unbound TFunction!
and if I comment it out, my game run, however my originally white wall looks like this:
not the BGRA (120,120,120,120) I was hoping for
Any insight would be really nice, been stuck on this for 6 hours now
